Mpandroidchart: Showing "No chart data available" although non-empty data has been set.

[dominikschubert]

The Charts semi-randomly show "No chart data available" instead of the chart data. If they are touch-enabled, they do render correctly after the first touch though.

Could you be a bit more specific? I do not fully understand the issue.

[dominikschubert]

Any touch event on the second chart now will suddenly show its linechart.
I'm setting the data for both charts in a postExecute method of an AsyncTask.

I've reproduced the issue with both a Nexus 4 and Nexus 5

My Layout

<com.github.mikephil.charting.charts.LineChart
   android:id="@+id/chart2"
   android:layout_width="match_parent"
   android:layout_height="180dp" />

My Activity

LineChart lineChart = (LineChart) findViewById(R.id.chart2);
ArrayList<Entry> lineList = new ArrayList<Entry>();
lineList.add(new Entry(5f, 0));
lineList.add(new Entry(15f, 1));
lineList.add(new Entry(3f, 2));
lineList.add(new Entry(10f, 3));
lineList.add(new Entry(4f, 4));
LineDataSet learnDataSet = new LineDataSet(lineList, "Line");
LineData lineData = new LineData(strs(5), learnDataSet);
lineChart.setData(lineData);

Are you calling invalidate() to refresh the chart?

[dominikschubert]

Calling lineChart.invalidate() after lineChart.setData(lineData) seems to work for now since without it the LineChart's onDraw somehow never gets called after the data has been set.

The strange thing is that I couldn't reproduce the bug in Genymotion for example and it renders correctly when using the Debugger.

I have same problem. Even I have some data, pie chart started to not showing and printing "No chart data available" text. And sometimes it does not print that text also just the categories with colored little rectangles on top-right.
lineChart.invalidate() does not work for me. Is there another solution? Thanks.

[crescent7272]

Sorry solved the problem. There were really no data. thanks

@crescent7272 could you tell me how you solved the problem, im in the same situation, and don't know how to fix it?

[crescent7272]

@hellbreaks actually it was not a real problem because there were really no data in my case. As I remember I had changed some place in my code but after I forgat that, so as a result my data set was empty. When my data set is not empty there is no problem.

solved the problem thanks @PhilJay and @dominikschubert
