MPAndroidChart - How to change the color of PieChart center Background?

问题

Im trying to use the MPAndroidChart library to develop a circular chart. But only Pie chart is available. So i tried giving two xvalue coordinates, with one color similar to background. So i got something similar to circular chart. But i'm not able to change the background color and font color of center text inside the pie chart?

Thanks!

回答1:

There are two possible solutions:

Retrieve the Paint object used by the chart to draw the "center-hole" and modify it the way you want

Paint p1 = mChart.getPaint(Chart.PAINT_HOLE);
p1.setColor(...);

Paint p2 = mChart.getPaint(Chart.PAINT_CENTER_TEXT);
p2.setColor(...);

Or use this, if you only display one value anyway: CircleDisplay

回答2:

To set center color:

mChart.setDrawHoleEnabled(true);
mChart.setHoleColor(...);

To set center text

mChart.setDrawCenterText(true);
mChart.setCenterText(...);
