I developed an app for Android using achartengine for some charts. I have 68 XYseries in my chart, but I want to have only 2 Legends. All XYSeries in red = one legend. All XYSeries in green = second legend.
Also I need manual Labels for the Y Axis. Y=1 should be g for example.
There is a setShowLegendItem(boolean showLegend)
method in SimpleSeriesRenderer
, so it is inherited by XYSeriesRenderer
. You should call this method for most of your renderers excepting 2 of them.
In order to have custom Y axis labels, you need to do the following for each such lavel:
renderer.addYTextLabel(y, "text");
And you also need to disable the default labels:
renderer.setYLabels(0);
