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.

toScreenPoint result is off #367

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I'm adding a touch slider on a graph chart, using toRealpoint and toScreenpoint 
to convert coordinate system. It worked fine if the the Renderer.setXAxisMin 
and Renderer.setXAxisMax are set to the first and last points in the data 
collection.

But if I set min and max to other value to get some zoom in and out effects, 
the slider position will be off. I called GraphicalView.repaint(). Is this an 
achartengine bug or do I need to do something to update the internal 
properties? 

What version of the product binary library are you using?
I tried 1.2.0 and 1.1.0

Is the "slider" using other scale than 0?

No, I'm not using other scales. I saw APIs with scale argument, but I'm not 
using them.
