AChartEngine is a charting library for Android applications. It currently supports the following chart types: line chart area chart scatter chart time chart bar chart pie chart bubble chart doughnut chart range (high-low) bar chart dial chart / gauge combined (any combination of line, cubic line, scatter, bar, range bar, bubble) chart cubic line chart All the above supported chart types can contain multiple series, can be displayed with the X axis horizontally (default) or vertically and support many other custom features. The charts can be built as a view that can be added to a view group or as an intent, such as it can be used to start an activity. The model and the graphing code is well optimized such as it can handle and display huge number of values. AChartEngine is currently at the 1.0.0 release. New chart types will be added in the following releases. Please keep sending your feedback such as we can continually improve this library.

TimeSeries disappear when hardware acceleration is turned on #371
Dear AChartEngine Team,
first, let me thank you for an awesome library! Thank you!
Please keep up the good work.
Issue:
TimeSeries disappear on certain zoom & pan levels when the hardware
acceleration is turned on. You can see the issue in the 3 attached screenshots.
It reminded me of the following error:
http://code.google.com/p/achartengine/issues/detail?id=57 that should have been
fixed, afaik.
LogCat reports the following in debug mode when a TimeSeries disappeard and you
kepp on zooming/panning the chart on a Nexus 7 (2013) running Jelly Bean 4.3:
...
11-20 20:47:47.953: W/OpenGLRenderer(1804): Path too large to be rendered into
a texture
11-20 20:47:47.963: W/OpenGLRenderer(1804): Path too large to be rendered into
a texture
11-20 20:47:47.983: W/OpenGLRenderer(1804): Path too large to be rendered into
a texture
...
Switching off the hardware acceleration resolves this issue on the nexus 7 (see
the attached code).
Devices running API level < 11 (Honeycomb) seem not to be affected (tested with
a 2.2 device).
What steps will reproduce the problem?
Please use the attached Activity (TestActivity.java) to reproduce this issue.
Code was stripped from anything unnecessary.
What is the expected output?
TimeSeries should be visible at every zoom & pan level (if they are in the
current viewing window of course) with hardware acceleration turned on.
What version of the product binary library are you using?
achartengine-1.1.0.jar
Please provide any additional information below.
- compiled against api level 19 (kitkat)
Manifest:
- android:hardwareAccelerated="true"
- android:targetSdkVersion="19"
- android:minSdkVersion="7"
Cheers,
Chris
