I am new to qwt and needs help on the following issue.
I am using QWTPlot. It works fine normally when I plot data. I see proper scale division.

However in certain conditions, when I zoom and unzoom the plot it leaves some space on both the axis before start painting.
The start of the axis is shifted (its not margin, margin is set to 0) as seen in the attached image.

Appreciate any pointers to resolve the issue. What property could I modify to get the proper plot behavior?plot_gap_issue.png

Thanks
