What do you mean by "drawing the chart 30 times"? Do you have 30 chart views?

[faizandedia]

No, just refreshing graph view with different data

[PhilJay]

Can you show some code of how you setup & refresh the chart?

I am also experiencing the same issue. On my dashboard fragment, I have two pie charts and one bar chart. User is often navigated back to dashboard and in memory profiler in Android studio I see that each time additional three MB get allocated, when I navigate to some other Fragment from it, those MB don't get garbage collected.

I even put

@Override
public void onStop()
{
    if (totalCountChart != null)
    {
        pieChartLocations.clearAllJobs();
        totalCountChart.clearAnimation();
        totalCountChart.clear();
        totalCountChart = null;
    }
    if (pieChartLocations != null)
    {
        pieChartLocations.clearAllJobs();
        pieChartLocations.clearAnimation();
        pieChartLocations.clear();
        pieChartLocations = null;
    }
    if (pieChartItems != null)
    {
        pieChartLocations.clearAllJobs();
        pieChartItems.clearAnimation();
        pieChartItems.clear();
        pieChartItems = null;
    }

    super.onStop();
    System.gc();
}

in my dashboard fragment, but it doesn't help.

Later I traced that in your DataRenderers you have bitmap fields and somewhere in between version 2.1.4 and version 2.1.6 the new method

   /**
     * Releases the drawing bitmap. This should be called when {@link   LineChart#onDetachedFromWindow()}.
   */
    public void releaseBitmap() {
        if (mDrawBitmap != null) {
             mDrawBitmap.recycle();
             mDrawBitmap = null;
        }
   }

was introduced in but I don't think it gets called anywhere, maybe I am wrong.

The problem is that I see that Bitmap.createBitmap in memory tracer takes those around three MB, and I think that the releaseBitmap should be called somewhere in chart.clear() method

P.S. why the hack so many clear methods, shouldn't one public call all of them 😄

P.S.2 it is big memory leak, so I think the instructions for clearing the chart/releasing memory should go in your main readme file.

[jaredsburrows]

@faizandedia What version?

[brcinho]

In my case 2.1.6
