When using non-grouped BarData CombinedChart clips the outer most bars.
Here is a quick example I made by changing BarChartActivity in the Example project to use CombinedChart.
If you can point me in the right direction I'd be happy to help try and fix the problem.

I was able to get around the above issue by using the following code:
XAxis xAxis = mChart.getXAxis();
xAxis.setAxisMinimum(data.getXMin() - .5f);
xAxis.setAxisMaximum(data.getXMax() + .5f);
This shouldn't be required so I am leaving the issue open so that it will hopefully be fixed.
@morriscodes Thanks, it worked for me
