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.

[Feature request] Highlight a bar in a BarChart #431

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
A nice way to highlight a bar would be a nice addition to this library. Right 
now, we can get the callback when clicking a bar chart like so:

stackedBarChart.setOnClickListener(new View.OnClickListener())

and get a SeriesSelection by calling stackedBarChart.getCurrentSeriesAndPoint() 
which provides us with the series and the point in the series. 

However, the only way to highlight this selection right now is to remove the 
selection from the series and add a new series with a new color on that 
position as explained by Dan on SO 
(http://stackoverflow.com/questions/18484794/change-color-of-selected-bar-in-ach
artengine).
