java - force close with zoom and pan limits in AChartEngine -


this code,,

mrenderer.setxaxismin(0); mrenderer.setxaxismax(38); mrenderer.setyaxismin(40); mrenderer.setyaxismax(110);  mrenderer.setpanlimits(new double[] { 0, 38, 40, 110 }); mrenderer.setzoomlimits(new double[] { 0, 38, 40, 110 }); mrenderer.setaxescolor(color.gray); mrenderer.setlabelscolor(color.gray); mrenderer.setpointsize(8); mrenderer.setxlabels(12); mrenderer.setylabels(10); mrenderer.setshowgrid(true); mrenderer.setapplybackgroundcolor(true); mrenderer.setxlabelsalign(align.right); mrenderer.setylabelsalign(align.right); mrenderer.setzoombuttonsvisible(true); mrenderer.setbackgroundcolor(color.black); mrenderer.setzoomrate(1.05f); mrenderer.setlabelscolor(color.white); mrenderer.setxlabelscolor(color.white); mrenderer.setylabelscolor(0, color.blue);

app behaves normal without zooming,,app force closes when zoom , start pan

panning restricted limits without zooming when pan after zooming beyond limit causes null pointer exception,,

the logcat result,,
