Hi,
you've made the GraphView-Lib as a Git-Submodule. Would be nice to mention that in your readme cause git doesn't clone submodule automatically.

I want to add the Months name on the Xaxis of the Chart how to do it , I can see any thing to achieve this , Following is the method which makes the index on the xAxis

GraphViewSeries exampleSeries = new GraphViewSeries(new GraphViewData[] {
          new GraphViewData(1, 2.0d)
          , new GraphViewData(2, 1.5d)
          , new GraphViewData(3, 2.5d)
          , new GraphViewData(4, 1.0d)
});

So how can I set the months name on the XAxis

Hi everyone
I'm very pleased with the library, great works!

Problem is, I don't understand why it behaves inconsistently, meaning that one time it shows like this (without date X labels and incorrect Y axis rounding)

in place of the correct display

I'm following the example Dates.java
https://github.com/jjoe64/GraphView-Demos/blob/master/app/src/main/java/com/jjoe64/graphview_demos/examples/Dates.java

if (story.getId().equals(storyId)) {
    GraphView graph = (GraphView) findViewById(R.id.graph);
    DataPoint[] dataPoints = new DataPoint[story.getMetrics().size()];
    int i = 0;
    for (Story.Metric metric : story.getMetrics()) {
        dataPoints[i] = new DataPoint(metric.getDate(), (int)metric.getConversations());
        i++;
    }
    LineGraphSeries<DataPoint> series = new LineGraphSeries<DataPoint>(dataPoints);
    series.setAnimated(true);
    graph.addSeries(series);
    graph.getGridLabelRenderer().setLabelFormatter(new DateAsXAxisLabelFormatter(graph.getContext(), new SimpleDateFormat(LABEL_DATE_FORMAT)));
    graph.getGridLabelRenderer().setNumHorizontalLabels(dataPoints.length);
    // as we use dates as labels, the human rounding to nice readable numbers
    // is not nessecary
    graph.getGridLabelRenderer().setHumanRounding(false);

    // set manual x bounds to have nice steps
    graph.getViewport().setMinX(story.getMetrics().get(0).getDate().getTime());
    graph.getViewport().setMaxX(story.getMetrics().get(story.getMetrics().size() - 1).getDate().getTime());
    graph.getViewport().setXAxisBoundsManual(true);

}

I'm really puzzled..

thanks

I want to mark the intersection of multiple series in Line graph? Can some one provide a sample to achieve it?

tried samples on Nexus7, compiled with Android 4.2.2 and it seems that Realtime Graph sample doesn't correctly do scrollToEnd=true within GrahViewSeries.appendData method.

From video you can se that Y labels actually updates but linechart stays same.
I created video but only images are allowed :) - I can send it to you by email.

How to set x axis to be date and automatically change by scrolling? thanks

Hello Team,

Please give any way to break line graph when we are updating multiple series with respect of time. if we are unable to find value in any series than i want to show break then when value not available.

When I put static labels only in the y-axis, happens this:

Well, I just want the date, and what seems to happen is that it puts the two values on the same axis (x-axis). Here's my code:
`
class MainActivity : AppCompatActivity() {

private var mNumLabels: Int = 4

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)
    val graph = findViewById<GraphView>(R.id.graph)
    initGraph(graph)
}

fun initGraph(graph: GraphView) {
    // generate Dates
    val calendar = Calendar.getInstance()
    val d1 = calendar.time
    calendar.add(Calendar.DATE, 1)
    val d2 = calendar.time
    calendar.add(Calendar.DATE, 1)
    val d3 = calendar.time

    // you can directly pass Date objects to DataPoint-Constructor
    // this will convert the Date to double via Date#getTime()
    val series = LineGraphSeries(arrayOf<DataPoint>(DataPoint(d1, 2.0), DataPoint(d2, 5.0), DataPoint(d3, 3.0)))
    graph.addSeries(series)


    series.isDrawDataPoints = true
    series.isDrawBackground = true
    // set date label formatter
    graph.gridLabelRenderer.labelFormatter = DateAsXAxisLabelFormatter(graph.context)
    graph.gridLabelRenderer.numHorizontalLabels = mNumLabels


    // second series
    val series2 = LineGraphSeries(
        arrayOf(
            DataPoint(d1, 3.0),
            DataPoint(d2, 3.0),
            DataPoint(d3, 6.0)
        )
    )
    series2.title = "speed"
    series2.isDrawBackground = true
    series2.color = Color.argb(255, 255, 60, 60)
    series2.backgroundColor = Color.argb(100, 204, 119, 119)
    series2.isDrawDataPoints = true
    graph.addSeries(series2)

    // second series
    val series3 = LineGraphSeries(
        arrayOf(
            DataPoint(d1, 3.0),
            DataPoint(d3, 2.0)
        )
    )

    series2.title = "HEY"
    series2.isDrawBackground = true
    series2.color = Color.argb(255, 255, 60, 60)
    series2.backgroundColor = Color.argb(100, 204, 119, 119)
    series2.isDrawDataPoints = true
    graph.addSeries(series3)

    // legend
    graph.legendRenderer.isVisible = true
    graph.legendRenderer.align = LegendRenderer.LegendAlign.BOTTOM

    // set manual x bounds to have nice steps
    graph.viewport.setMinX(d1.time.toDouble())
    graph.viewport.setMaxX(d3.time.toDouble())
    graph.viewport.isXAxisBoundsManual = false

    graph.gridLabelRenderer.setHumanRounding(false)

    val staticLabelsFormatter = StaticLabelsFormatter(graph)
    staticLabelsFormatter.setVerticalLabels(arrayOf("low", "hey", "high", "wei", "wai"))
    graph.gridLabelRenderer.labelFormatter = staticLabelsFormatter
}

}

`

When I take this: val staticLabelsFormatter = StaticLabelsFormatter(graph) staticLabelsFormatter.setVerticalLabels(arrayOf("low", "hey", "high", "wei", "wai")) graph.gridLabelRenderer.labelFormatter = staticLabelsFormatter
Everything works fine... but then I can't use static labels. Can you help me?

i can't build gradle.
i just checkout and build it.
and the all other things is work fine.

Hello there,

After opening a new empty android studio project and typing compile 'com.jjoe64:graphview:4.2.1' into the app's build.gradle file, I get this error. It is also appearing on android studio of a colleague of mine:

Program type already present: android.support.v4.app.FragmentTransitionCompat21$1

Any idea what's going on?

Thanks a lot before hand, excited to get started with GraphView! :)

getting illegal argument exception on final GraphViewSeries exampleSeries3 = new GraphViewSeries("Leaves",Color.BLUE,new GraphViewData[] {

In examples you use that method (setLegendSpacing). It doesn't exists anywhere.

I have a personal implementation of a multicolored graph (the line and filled graph), and it would be nice to add here, but i've then switched to code similar to official android guide on graphs (navigable one),
do you want me to pull some code about it or you already have some ideas?

Hi, their support date redundance based on picture I attach and below following code that i follow

GraphViewSeries is missing from GraphView-2.5.jar

This isn't so much an issue but a question about using GraphView inside a fragment activity. I am getting an error Cannot resolve constructor LineGraphView

GraphView graphView;
graphView = new LineGraphView(this, message);
graphView.addSeries(exampleSeries); // data

I posted on stackoverflow and then realized I should ask here

Hi,

I need to create a custom graph according to my need.
Actually, i am updating the graph based on sound by recording audio. I got the result in byte array.
But i am unable to assign byte array to graph. :( As, graph object doesn't have any method to show the byte array. It just have method to addSeries. i.e. Object of DataPoints which have 2 double values.

I need to pass a byte array and need to update the graph accordingly.

For that i need to customize the java classes of the library but it's not allowing me as it is in jar.

Please help, or if you have some other solution w.r.t. this then please do reply..

Thank you in advance.

I need to create the graph like this,

"diagramms" instead of "diagrams"

i m using eclipse have made prj in eclipse and have added jar file as lib but still i m getting error GraphViewSeries in this class when trying to use this code

GraphViewSeries exampleSeries = new GraphViewSeries(new GraphViewData[] {
new GraphViewData(1, 2.0d)
, new GraphViewData(2, 1.5d)
, new GraphViewData(3, 2.5d)
, new GraphViewData(4, 1.0d)
});

• start with impressive graphs
• example group for each chart type
• realtime example with lots of data
• simple examples with all features in 4.2
• use cardviews
• fullscreen button -> change to horizontal orientation

Good morning
I am just interesting about future of GraphView
Is any chance to see the additional development of
pie chart
polar chart
radar chart?

I used the example code of RealtimeGraph at https://github.com/jjoe64/GraphView-Demos/blob/master/graphviewdemos/src/main/java/com/jjoe64/graphviewdemos/RealtimeGraph.java

Whenever the screen orientation is changed, the graph is restarted again and all the previous data is not displayed.

How do i stop restarting the graph every time the screen orientation is changed?

Hi!

These errors popped up when I tried to run the app from the get go, without modifying any code from the GraphView-Demos-master project I downloaded from here:
[https://github.com/jjoe64/GraphView-Demos]

Any clue as to what's going on? Thanks a lot before hand!

if you scale out you will see x lables that doesn't have data , even in you demo if you try to scale out you will se the bug .

Hey joe, i am trying to create real time graph . The data on graph will come from bluetooth , it's a massive amount of data and very fast rate lets say 1sec =60 samples of data

problem is when i used appendata to add the data and fixed max data points to 400 ,it crashes after some time . i debug it , it causes memory leakage

final String[] arr = str.replace("[", "").replace("]", "").split(",");

for (int i = 0; i < arr.length; i++) {
mSeries.appendData(new DataPoint(graph2LastXValue, Double.parseDouble(arr[i])),true,380);
//DataPoint v = new DataPoint(graph2LastXValue,Double.parseDouble(arr[i]));
// myArr[i]=v;
// mSeries2.appendData(myArr[i], true, 380);
graph2LastXValue++;

}

Had a bit of a look and im fairly certain this doesn't exist yet.

graphview.getGraphAsBitmap
graphview.getAllSeriesData

as examples

If you set graph.getViewport().setXAxisBoundsManual(true); for both the X and Y axes but then only supply a minimum for both (0 for each), the X axis will increase automatically with data while the Y axis is initiated at 1 on the graph and will not move. How do you get around this? In an older version of the code I'm running, this bug didn't happen.

Note: the data I have is coming in VIA bluetooth and being appended to a series in real time, so I cannot set a maximum value to begin with.

In BarGraphFragment call by error FullscreenExample.ADVANCED_LINE_GRAPH instead of FullscreenExample.ADVANCED_BAR_GRAPH

    new AdvancedBarGraph().initGraph(graph);
    rootView.findViewById(R.id.cardAdvancedBarGraph).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            openFullscreen(FullscreenExample.ADVANCED_BAR_GRAPH);
        }
    });
    rootView.findViewById(R.id.imgFullscreen2).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            openFullscreen(FullscreenExample.ADVANCED_LINE_GRAPH);
        }
    });
    rootView.findViewById(R.id.imgSource2).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            openSource(FullscreenExample.ADVANCED_LINE_GRAPH);

I have an activity that holds 2 fragments with a viewpager to scroll between them. In the first fragment i have an mapfragment and a graphview which is scalable. In the second one, i have some basic stuff like textviews and such. Now, if i want to browse in my graphview, i scroll a little bit and then the viewpager takes over and takes me to the other fragment. Is there a way on how i can fix this?

Hi everyone!

While using this library(thanks for it!) I stuck when I need to reset data on my GraphView.

I store my data as LineGraphSeries object, independent from activity lifecycle, so when activity created, or resumed I need to refresh data in another LineGraphSeries object which is associated with GraphView.

I check source code of BaseSeries class and found method resetData(E[] data), but it take as input only array of data and it is very hard to get those array, because in BaseSeries class there is only one method to getting data: getValues() and it returns Iterator<E>.

So to get array I need go through this iterator and write values to ArrayList first(because Iterator can't tell us how much elements it has), and finally I can create array and write to it values from ArrayList.

I think it's very long and not effective, so I suggest with minimum changes:

• add getter method to BaseSeries class, which will return [] E - array of data values

And to increase usability in this reseting data case:

• add overload constructors to BaseSeries, LineGraphSeries, BarGraphSeries, PointsGraphSeries which will take as argument ArrayList <E>
• add overload version of resetData() method, which will take as argument ArrayList
• add getter method to BaseSeries class, which will return ArrayList<E>

So what do think about my suggestion?

Is it true that the graphs do not display in classes that extent the SherlockFragmentActivity? If i extend to Activity it works but would like the support for SherlockFragmentActivity as well.

it dosent seem to scale according to my values.

With ADT (version 21.0.0.v201210310015-519525)
The library is correctly used for autocompletion, but is not used at run time, resulting in a java.lang.NoClassDefFoundError !

Correction:
Move jar from lib ditectory to libs one (with a "S")
