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.

Labels and values in pie chart are hidden behind the pie chart segments #445

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1.Draw a pie chart with labels and text values

What is the expected output? What do you see instead?
Labels and values should always be in front of the pie chart itself, but 
sometimes they are hidden behind it. The reason for this is because all 
segments together with their values and labels are drawn in order one after 
another so the segments drawn later are drawn "in front" of the labels and 
values of segments drawn earlier.

Please provide a source code snippet that we can use to replicate the
issue.
I've attached an example screenshot showing the problem.

What version of the product binary library are you using?
I'm using achartengine source from SVN revision 569

Please provide any additional information below.
I've attached a patch with a fix for this issue. The fix basically delays 
drawing of all the text (labels and values) after all the pie segments are 
drawn.
