What steps will reproduce the problem?
1. <mc:MicroAreaChart dataProvider="{acMC}" height="100%" width="100%" 
    color="0x66CCFF"  />    
2.
3.

What is the expected output? What do you see instead?

The color of the area chart should change to 0x66CCFF, however, it stayed 
black.

What version of the product are you using? On what operating system?

I downloaded the source on 12/05/2008, and created a swc using FB3.

Please provide any additional information below.

I also tried the following, none worked:
1. colors="{ new Array( '0x66CCFF' ) }"
2. fills="{ new Array( new SolidFill( 0x66CCFF, 0.3 ) ) }"

I think there's a bug in MicroAreaChart.as Line 106.  My proposed change:
if( colors != null || !isNaN( color ) )

For some reason, I can't debug into useColor(Number) in BasicMacroChart.  
The return value of useColor seems to be null all the time (for me).

minor issue:
GeoFrame has styleName 'stroke' to define keylines.
Choropleth has styleName 'strokeItem' to define keylines

What steps will reproduce the problem?
1. go to
http://birdeye.googlecode.com/svn/trunk/ravis/RaVisExamples/example-binaries/RaV
isExplorer.html#
2. change the label layout
3. notice the labels are misplaced.
4.  Hit draw graph and notice them move to the appropriate location

What is the expected output? What do you see instead?
Expected output is the labels will be properly placed, but instead they are
all misaligned.

Taken from SVN 5/7/2009

We added the possibility to show the percent into pie chart.

What steps will reproduce the problem?
1. sometimes two nodes have two relations, so we need two line between two 
nodes, and two edgelabel, how to do it?
2.

Please provide any additional information below.

hi all past from few day am seeing this radar chart it's really good work from 
many..i was trying to use XML as data Provider am not able to find .could any 
one help me out please 


thanks

What steps will reproduce the problem?
1. Set a colors array on MicroBarChart or MicroColumnChart

<microcharts:MicroBarChart backgroundColor="#DDDDDD" 
backgroundStroke="#888888" colors="[0x666666, 0x000000, 0x000000, 
0x000000, 0x000000]" height="40" width="200" stroke="#888888" 
showDataTips="true" spacing="3" id="costChart" />

2. No columns appear, just an empty microchart background.

Here's the current code in createColumns()/createBars():
  if (colors == null || colors.lenght == 0)
      if (negative && dataValue < 0)
      column.fill = new SolidFill(_negativeColor);
      else
      {
    if (isNaN(color))
      column.fill = black;
    else 
      column.fill = new SolidFill(color);
      }

  Notice that there isn't an else case for the first if.  Missing {} make 
this difficult to notice at first glance.


Here is fixed code for both classes:

   if (colors == null || colors.length == 0) {
    if (negative && dataValue < 0) {
        column.fill = new SolidFill(_negativeColor);
    }
    else
    {
        if (isNaN(color)) {
            column.fill = black;
        }
        else {
            column.fill = new SolidFill(color);
        }
    }
}
else {
    if (i < colors.length) {
        column.fill = new SolidFill(colors[i]);
    }   
    else {
        // Use the last color in the array if colors size is less
        // than the number of data points.  
        column.fill = new SolidFill(colors[colors.length - 1]);
    }                   
}

Cartesian chart accepts only a string type for categoryField. If object is 
set into categoryField, object string representation is keep and this cause a 
bug in stackElement if more objects are the same string representation.

We have replace Array by Dictionary class to correct this.

What steps will reproduce the problem?
1. the order inside the elements section has no
effect on their display order.

What is the expected output? What do you see instead?
Elements must show up according the elements section order.

Please use labels and text to provide additional information.

What steps will reproduce the problem?
Project in attached zip file does not render the node labels and the same 
application rendered labels correctly in previous version of ravis.

What is the expected output? What do you see instead?
Graph renders with no node labels in the graph.

What version of the product are you using? On what operating system?
Library built and/or released with svn revision 1822.

I have attached a patch that makes the labels render, but this does not seem to 
be the proper solution.  I am fairly new to flex and am not 100% sure what the 
correct solution would be.  I can think of plenty of incorrect solutions :-P

Line 329-331 of EnhancedVisualGraph is as follows

            if((_nodeLabelRendererFactory != null) && 
                (vn is IEnhancedVisualNode) && 
                (_edgeRendererFactory is IControllableEdgeRenderer)) {

To the best of my knowledge _edgeRendererFactory is of type IFactory and will 
never be a IControllableEdgeRenderer.

Removing this check makes the labels render, but I am assuming this validation 
was added for a legitimate reason.  An instance could be created from the 
factory and that could be checked against IControllableEdgeRenderer but that 
seems to not be the correct solution.

Anyway, I attached a patch with that line removed.  Applying it will make the 
labels render but removes the validation.

What steps will reproduce the problem?
1. create a visualGraph.
2. set ForceDirectedLayouter as the layout algorithm.
3. add nodes using visualGraph.createNode()

What is the expected output? What do you see instead?
the layouter should work properly instead of showing error.

What version of the product are you using? On what operating system?
source code upto revision 1822.
opearting system - Windows XP

Please provide any additional information below.
The problem is due to following code:-
803  /**
804  * @inheritDoc
805  * */
806  public function get visibleVEdges():Array {
807  return _visibleVNodesList.sortOn("id");
808  }

this should be replaced with
803  /**
804  * @inheritDoc
805  * */
806  public function get visibleVEdges():Array {
807  return _visibleVEdgesList.sortOn("id");
808  }

First, we added labelRotation parameter in BaseElement.
Second, we added the capability to show the filename over the column item.

I could not find libraries that defined events such as VGEdgeEvent.

== What steps will reproduce the problem? ==

For me, the following two lines do not work:
vgraph.unlinkNodes(selectedNode.inEdges[0].node1.vnode, selectedNode.vnode);
vgraph.linkNodes(vgraph.currentRootVNode, selectedNode.vnode);

ActionScript throws an error, which I have included at the bottom of the bug 
report.  I have reproduced this in multiple projects, and have included a 
modified demo project to reproduce this behavior.
1. Select a node other than the root node by using the keyboard
2. Click the "Change Parent" button at the bottom.  An error should occur.

== What is the expected output? What do you see instead? ==

I would expect that a new edge would be created (and rendered, given a 
vgraph.draw() call) linking the root node to the selected node.

== What version of the product are you using? On what operating system? ==

I am using revision 1828 of Ravis in Flex 3.5.

== Please provide any additional information below. ==

It appears the data for the newly created Edge is never set before the edge is 
rendered.  I have included the full stack trace below:

TypeError: Error #1009: Cannot access a property or method of a null object 
reference.

What steps will reproduce the problem?
1. Use a non-0 colors array with a MicroColumnChart

In the createColumns() method, this line will have a problem:
  if (colors == null || colors.lenght == 0)

Fix:
  if (colors == null || colors.length == 0)


What version of the product are you using? On what operating system?
  trunk (March 28, 2009), Windows

Why you didn't include the TTF fonts to svn? (please, see main.css file)

What steps will reproduce the problem?
1. Create a Flox container (HBox in a DataGrid for example), and set the 
width to be a value that will be decreased by the Box when it does its 
measurement, or just add other children so that the % width of the 
MicroChart is more than the width the chart will be allocated.

<mx:HBox xmlns:mx="http://www.adobe.com/2006/mxml"...
  <mx:Label width="30" text="{averageRequestsPerDay}" textAlign="right" />
    <microcharts:MicroLineChart width="100%" color="#666666"
          backgroundColor="#CCCCCC" height="20" 
          dataProvider="[3,7, 8, 0, 0, 4, 5]"
          negative="false" showDataTips="true"  />
</HBox>

2. When the chart is rendered, data points are lost.  
The attached image, BasicMicroChart_percentWidthIssue.gif shows that only 
the first 4 points are rendered or a 8 data point dataProvider.



3. The issue seems to be the measure() method in BasicMicroChart which is 
basically assuming that the percentage value is accurate and has not been 
reduced by the parent's measurement algorithms.
  tempWidth = Math.max(0, percentWidth/100 * (parent.width - edgeMet.left -
 edgeMet.right));

4. The issue does not appear if the width corresponding to the 
percentWidth assigned to the Chart is not reduced by the parent's 
measurement algorithm.


What is the expected output? What do you see instead?
I'd expect to see all of the data points rendered, allowing the parent's 
measurement to flow down to the children instead of having the MicroChart 
child try to do it itself.

Possible fix:
Just have the percentWidth() method work like UIComponent - if 
percentWidth is changed, then invalidate the parent size, and have it set 
the width on the child, etc.

        override public function set percentWidth(val:Number):void
        {
            _percentWidth = val;

            var p:IInvalidating = parent as IInvalidating;
            if (p) {
                p.invalidateSize();
                p.invalidateDisplayList();
            }
        }

Then in the measure() method in BasicMicroChart.as, the percentWidth 
calculations can be removed.

The BasicMicroChart_possibleFix.gif image shows the result - all of the 
data points are rendered.

Please provide any additional information below.

A BasicMicroChart.as used for the fix with the percentWidth changes and 
measure() commented  lines is attached.


percentHeight could be similarly changed.

What steps will reproduce the problem?
1. Call a constructor of any layouter without the vgraph parameter
2.
3.

What is the expected output? What do you see instead?
Nothing should happen, since the null is a standard parameter of all the
layouters. But an error happen, because all layouters call the initModel()
method inside the constructor, which access the vgraph properties...

What version of the product are you using? On what operating system?
Last one

Only the half excess geometries was clear.

private function clearExcessGeometries(nbrOfItems:Number):void
{
    while (this.geometryCollection.items.length > nbrOfItems)
    {
        this.geometryCollection.removeItemAt(nbrOfItems++);
    }
}

The items length decreases in the same time that nbrOfItems increases ;-).
It's more efficient to don't increase nbrOfItems.

null pointer check is present in onElementRollOver method but not in 
onElementRollOut.

Now I am using the ravis library to display a topology graph. My project 
required me to implements a function that allows user to drag part of the graph 
to the 
other area and creating a new graph. Is there any thing like the "dragEnable" 
attribute allows me to drag subtree and copy it to the other container to create
an new graph?

BaseScale - isGivenInterval isn't set to false if dataInterval is set to NaN.

What steps will reproduce the problem?
1. The order of the elements section does not matter
2. Line element + column element  means that the line is always "behind" the 
columns. 


What is the expected output? What do you see instead?
The ordering should fix that

What version of the product are you using? On what operating system?
Trunk

What steps will reproduce the problem?
1. When there are multiple lines of text on node  
2. Size of visual graph is small, some labels gets overlapped with other ones 
3.

What is the expected output? What do you see instead?
On click on any node (i.e. primitive circle) graph will bring it to front. 

What version of the product are you using? On what operating system?


Please provide any additional information below.

We added a small function to show labels outside the pie or names outside the 
multiaxis radar.

What steps will reproduce the problem?
1. Create a MicroPlotChart using a colors array
<microcharts:MicroPlotChart width="200" height="40" showDataTips="true" 
dataField="val" backgroundColor="#DDDDDD" backgroundStroke="#888888" 
colors="[0xFFFFFF, 0xFFFFFF, 0, 0xFF0000, 0]" dataProvider="{dp}" 
negative="false" radius="10" />

2. Note that all of the circles show up with black fills, instead of 2 
white, 1 red, 2 black.


Analysis:

In createPlots() in MicroPlotChart.as, the line for using the colors array 
is correctly being called, based on the flex debugger:

  if (colors != null) {
    plot.fill = new SolidFill(useColor(i));
  }

The Degrapha asdocs for SolidFill say that the first arg should be an 
Object specifying a color value (unit or string).

However, the useColor() method in BaseMicroChart.as is returning a 
IGraphicsFill object, not a color value:
  protected function useColor(indexIteration:Number):IGraphicsFill

The Degrapha code is just treating an unknown type of object input as 
black, so everything shows up that way.


Fix: Use the fill returned from useColor() instead of creating a SolidFill.
  if (colors != null) {
    plot.fill = useColor(i);
    //plot.fill = new SolidFill(useColor(i));
  } 

The attached image shows that the different colors now appear.

What steps will reproduce the problem?
1. Draw any graph with qavis that contains gridlines
2. Resize the browser window after the content has been rendered

What is the expected output? What do you see instead?
New gridlines and the old ones should be invalidated. Instead there is a mix of 
new and old 
gridlines leading to a "messy" grid.

What steps will reproduce the problem?
Use the attached project in the Zip file.
Adding a node renderer whose labelCoordinates method puts the label in the same 
location draws labels underneath the rendered nodes.
In My attached example project I set the itemRenderer to MyNodeRenderer.
MyNodeRenderer simple makes sure that the labelCoordinates method draws the 
label on the same xy as the node itself.

Expected: Labels on top of nodes
Actual: Labels covered by nodes

What version of the product are you using? On what operating system?
Subversion version 1828

Please provide any additional information below.
I am able to fix this by extending EnhancedVisualGraph overriding 
createVNodeComponent and reordering the children in the nodeLayer so that the 
node renderers are added first and the labels are added after.  This forces the 
labels to be drawn  on top of the nodes.
I am willing to accept that my implementation is wrong and would welcome a 
suggestion of a different way to implement it.  I considered not using a label 
renderer and just making the label part of the node.   Seems like this might 
also fix the issue.

What steps will reproduce the problem?

As radarcharts aren't available in the compiled swc ( they are in the source ), 
i tried to compile the entire library up into a new swc. 

However, while trying to do this i saw that some of the degrafa classes where 
missing. 

So after doing some research i realized that you are providing an old version 
of degrafa ( 3.1 ), there newer version ( 3.2 ) however does have these 
classes. 

One of these classes is RadarTextPlus ( geometry package ) 

Quick Fix : 

Download the 3.2 swc file from the degrafa googlecode page. Delete the degrafa 
3.1 swc and compile everything up with the new 3.2 swc :)

1. We i compile

1. Use showDataTips with a MicroBarChart with a large enough width to
   see where the tooltip location appears.

<microcharts:MicroBarChart width="200" spacing="3" showDataTips="true"
   height="40" dataProvider="[200, 80, 30, 10]"/>

2. The attached MicroBarChart_tooltip_prefix.gif image shows that the 
tooltip appears in the lower corner, instead of centered vertically like 
the other microcharts.


What is the expected output? What do you see instead?
Expecting to see a vertically centered tooltip location.

In the createBars() code, the startY value is incremented after it is used 
for positioning the column, but before the tooltip location is specified.

  startY += columnWidth + spacing;

A fix is either to move the startY change to below the 
  if (showDataTips)

block, or to change the positioning of the createToolTip to subtract the 
spacing value:

  geomGroup.createToolTip(data.getItemAt(i), _dataField, space+startX + 
posX, space - spacing + startY - columnWidth/2, 3);

The attached MicoBarChart_tooltip_postFix.gif file shows the vertically 
centered tooltip after the fix is applied.

I am using the MicroLineChart in a custom item renderer in a Datagrid. I
have around 100 rows in the Datagrid. Each MicroLineChart consists of
approx. 40 datapoints.
Now it takes around 2 sec to render this datagrid, and approx. 5 if I also
show datatips.
Is there a way to speed up the rendering or a recommended way how to use
MicroLineCharts in a custom item renderer?
Later I might have hundreds of datapoints, and this will take very long to
render.

Thank you,
Martin
