Trouble Getting Axis Centered On Origo In Achartengine

I'm having trouble getting AChartEngine to center the actual visible axises on Origo instead of having them along the left- and bottom of the chart. I need to have the axises like

Solution 1:

I made some modifications to AChartEngine 1.0.0 to make it possible to display axises in the center of the plot. Use code below to set the axises to center.

XYMultipleSeriesRenderer.setXAxisAlign(Align.CENTER, 0);
XYMultipleSeriesRenderer.setYAxisAlign(Align.CENTER, 0);

XYMultipleSeriesRenderer.patchXYChart.patch

And here is an example on how it may look

Solution 2:

There isn't a better answer than the one you mentioned. Just make sure that you calculate X and Y ranges such as your data fits inside and also make sure that the range you set is centered on the 0 point:

renderer.setXAxisMin(-value);
randerer.setXAxisMax(value);

and the same for the Y axis.
