x-axis label is not visible after using fitScreen()

I only get 2 datas here so setVisibleXRangeMaximum() function creates lots of space so avoid that I'm using fitScreen() method but that causing bellow issue . Refer bellow screen shot

Reproduce the report with only two data points, first using setVisibleXRangeMaximum() and then fitScreen(), and compare the x-axis label visibility with the attached screenshot. Trace the fitScreen() entry point and the x-axis rendering path; done means the label is visible without introducing excessive chart space.
