When you have multiple charts on view, it looks boring that they all have same color, it would be nice to create a property to indicate if chart must use a random starting color index

Can't seem to turn this off. My users are going to expect to be able to click into a specific data point with this feature on.

Tried to do this:

<lc:Axis MinValue="0" Labels="{Binding PrimaryAxisLabels}" Separator="{x:Null}"/>

Got a NullReferenceException.

Hello,

it would be great to add multiple y axes (primary axes) für the line series plot. So that you can say, line series 1 and 2 will use primary axis 1 and line serie 3 will have the separate primary axis 2.

Regards

Worked nicely, but there is an issue.

PieChart.Series = new ObservableCollection
{
//if you add more than one serie to pie chart, they will be overridden
new PieSerie
{
PrimaryValues = new ObservableCollection { 8 }, // Only one component
Labels = standardLabels
}
};

=> Then the chart animates and disappears.

How do I add legend in c# not in xaml into a PieChart? I trying to add it in winforms, any pointers how to do it?

The last label is truncated due to cropping.

I have been finding chart library with zoom and pan supported so I would like to know if your library could be supported for wp8 or not

Since it was based on many pieces of code, each peace works appart, we can join them all in one loop.

Is live-charts could use mvvm pattern binding data and display? If it can，how to use？Thanks！

I'd like to see the ability to rotate the axis labels so that I can display them veritically or at some arbitrary angle.

I am trying to use a line or bar chart to graph a total number of tickets. In this case it doesn't make sense to plot anything below zero but I am unable to control it.

Hello dear Rodriguez
First, I want to thank you for this contribution it's very an easy way to create charts

Then, In this new release 0.4 the Piechart does not hover (show tooltip) i tried PieChart.Hoverable=true like the older release but it doesn't work.

Thank you

Hello,

it would be great if the library will be supported in C# 4.0.

I changed lines like this one:
var labels = SecondaryAxis.Labels?.ToArray();

in that one:
var labels = SecondaryAxis.Labels != null ? SecondaryAxis.Labels.ToArray() : null;

and then it will compile and work unter C# 4.0

These are not much changes but a few.
Try to compile it with Visual C# 2010 Express for example and yu'll see it.

Regards

Hi,

It would be great to be able to add Text objects, or images, to the chart or series similar to what ZedGraph provides in ZedGraphControl.GraphPane.GraphObjList.Add(text). Thanks.

Cheers

The XAML is a lot cleaner being able to bind most things as of v0.5.6, but I would like to be able to bind the axis label formatter. Can this be updated to a Dep Prop?

When Series is null this exception is thrown, in my case series are not initialized with the the view because they require to request data to the sever, Series.Plot should ignore this if series == null or any of the series in collection is null, maybe its cause becasue labels property is null

When adding a line series to a bar chart as the first series in the collection, the mouse-over only works on the line chart. It doesn't respond to the mouse being over one of the bars.

With the mouse near the line series point on the bar the mouse is over:

With the mouse closer to a line series point for another bar, but still over the same bar:

The line chart seems to handle labels for a lot of data better than the bar chart does. I would like if they were setup similar. I attached screenshots showing what I am talking about. These are using the same exact data.

I am doing a lot of changes in this library, with the changes you made and the ones i am about to push this 0.5 version will be the best by far (now line charts can draw 1,000,000 points in less than 10 ms). I am just seeing some new methods, that I would like to know what are they for what like this one:

thanks

Zooming works well, but it always zooms according to 0,0 chart point, it would be more user friendly if we move on X and Y according to user position on chart.

I think animating on rezising does not looks good

Hello,

one more request: It'll be glad to have axes titles at the line series plot.
Like "Time [s]" (horizontally below the secondary x axis) or "Cost [€]" (vertically next to each of the primary y axes).

Regards

- This shows the problem

- This one works

Hi, I'm trying to use PieChart and I set
PrimaryValues="{Binding VM.Obj.Prop, UpdateSourceTrigger=PropertyChanged, Mode=OneWay}"

VM.Obj.Prop is a property:
public List Prop
{
get {return _prop;}
set {
_prop = value;
RaisePropertyChanged(() => Prop)
}
}

So in RaisePropertyChanged() I generate PropertyChanged event but chart doesn't change. only If I resize the window it will be redrawn.
Am I doing everything right or I miss smth?

A lot of errors on debugging attempt in "WPFExample" project with 0.5.6 library. Does it really works correctly?

Instead of "Title Value" in the IndexedToolTip, there's no option to add binding text before the Value.

For example:

"High Temp 90 degrees" could be changed to "High Temp Dry 90 degrees", or "Low Temp 30 degrees" could be "Low Temp Frosty 30 degrees".

If there is some kind of overload I can use to add a descriptor before the value, that would be fantastic but I'm not quite sure how to implement it. I'd suffice with the tooltip, but the tooltip doesn't seem to display at all.

If we enable Paralell or async drawing will buff performance when many values and series

So I have a bar chart the following:

Primary Values = Assigned, In Progress
Secondary Values = 876, 119

When I add this to the chart I see this...

But I have zoom enabled and when I zoom it changes to this...

it does the same thing when zoom is disabled but it will always look like the first screenshot.

I think it would nice to be able to merge chart types. For example, have a bar chart with a line on it.

In a piechart, if an observable collection contains only zeros, it crashes.

based on #30 (comment), please check this

I'd like to add Candlestick chart with the next values on each point: date, time, open, high, low, close, volume. What steps should I do? Make copy of Series class and swith just doubles to candle class with mentioned properties? Then create CandleSeries class inherited from this Series copy and write a logic in Plot methods?

Would like the ability to provide my own content for the tooltip or to turn on/off data shown in it.

when adding new point to bar or stacked bar chart new bars do not animate. this is beacause by default it disables animation when charts grows, and this is fine for line chart and some others but not when using bars. It should be a protected variable that handles this behavior.

Hello,

it would be great that the plot value "Double.NaN" will be supported and will create a "gap" in the Line Series Plot.
I changed your great library quickly and it works, but it not coded well.

Regards

I'm updating a line chart dynamically and my data flat-lines to a single value. Instead of displaying a flat line the chart disappears entirely.

Hello,

I hope this section here is the right one for such questions. I can't findy any other discussion possibility.

When I set the minimum and maximum of the secondary axis like the following, this axis won't be fixed:
LineChart.SecondaryAxis.MinValue = 0;
LineChart.SecondaryAxis.MaxValue = 1000;
A new added point will be drawn on the right even if I have only 100 points in the chart. I expected that the values will be shown between 0 and 100 of the secondary axis and not over the whole range from 0 to 1000.
What do I need to change to get this behaviour?

It would be great if I could name a serie so if I have multiple series it will show the value and the name

The error thrown is

Exception thrown: 'System.ArgumentException' in WindowsBase.dll

Additional information: '-0.62894699242749' is not a valid value for property 'Width'.

When there are too many labels, the initial display has all of them bunched up.

After recalculating layout, the labels adjust properly.

Currently pie animations need to redraw all the chart everytime you make a change, it would be better to start from data is now, to the next state. From #47, This issue also refers to add it to many series as possible

I set the stroke and fill for a line series in a bar chart.

<lc:BarChart.Series>
    <lc:BarSeries PrimaryValues="{Binding MetricData}" Title="{Binding MetricName}"/>
    <lc:LineSeries PrimaryValues="{Binding GoalData}" Title="{Binding MetricName}"
                   Stroke="Green" Fill="Transparent"/>
</lc:BarChart.Series>

This is the chart I get:

this library could include a static list of formaters, for example currency, short date, long date, number, upper case, lower case.

- I would love if I could have a legend on the left or right side of this pie chart if possible

Would like to receive a Click event or equivalent when clicking on a data point. Should indicate which data point was clicked.
