问题 Is it possible to replace LimitLine with custom layout? So it looks something like this: I see few solutions for that: Perhaps there're methods inside library for customizations like this, are there any? Get coordinates of TextView where the value is stored and add custom layout on that place. But how can I reach this TextView ? Perhaps someone faced that problem. Please share your experience.

问题 In CombinedChart by adding chart.setFitBars(true) will make the first and last bars visible. I need to do the same for combining LineChart with BarChart. Now, first and last bars aren't visible completely. I've tried xAxis.setAxisMaximum(data.getXMax() + 1f); to extend X-Axis towards right side so that the last bar will get enough space.
