AchartEngine has two ways to scale a chart. First is the "button", and the second is the "fingers". Is there a way to disable one of them? I do not want to increase the fingers. Is it possible?
you can use XYMultipleSeriesRenderer methods to enable or disable scaling
mRenderer.setPanEnabled(false, false); mRenderer.setZoomEnabled(false, false); renderer.setZoomEnabled(false, false);
