@govind,
Can you kindly share a JSFiddle reproducing the issue you are facing?
From what we have observed, sometimes things get delayed mostly when we are not able to reproduce the issue – as there are 30+types of charts with elements like title, subtitles, legend, axisX, axisY, dataPoints, stripLines, labels, indexLabels, etc – it would take time for us to actually land up with your use-case or we may not be able to reproduce the issue when you are passing invalid options.
Having a JSFiddle helps us in figuring out the issue and many a times we can just edit your code on JSFiddle to fix the issue right-away.
