I have a stacked bar graph where I have restricted the viewport initially to show the last 10 values by setting viewportMinimum and viewportMaximum. This works as expected but when you pan the graph back to the earlier points the x axis labels are not rendering properly.
Can you kindly create and share a jsfiddle reproducing the issue you are facing, so that we can look into the options, understand your code better and help you out?
