Question

Is there a way to add padding\offset to top? See screen. Digits are cropped if LimitLine is at top:

Answer 1

I had the same issue and after a lot of searching figured there is no direct way to get that extra space. Here is how i did it:

//dont start at zero
yaxis.setStartAtZero(false);
//look at your dataset and set the min and max values of the y-axis at runtime
//keep the range with some extra space - as you want
yaxis.setAxisMinValue(4);
yaxis.setAxisMaxValue(8);

Code not to be used as-is : 4 and 8 above are numbers that suited my purpose - change the values as per your data points
