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.

Flickering while panning #106

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I have the problem that my chart flickers while i am panning it. This occus 
when i set the panlimits to the minimum an maximum value of my data set.

You can reproduce it if you change one line in your demo code:

In the File AverageTemperatureChart
Change
renderer.setPanLimits(new double[] { -10, 20, -10, 40 });
to
renderer.setPanLimits(new double[] { 1, 12, -10, 40 });

Now when you pan the chart, it flickers. I want that my chart fills the 
available space and cannot be panned outside the range of my dataset.

I hope it is clear what i mean? I use the latest version from your repository.

Thanks
Harald

This used to be an issue a very long time ago. Are you sure you are testing 
with the latest version in SVN?
What device are you testing on? I cannot see any flickering.
