Scaling of x-axis in GUI

I created a GUI for plotting step response of a control system transfer function. When I press push button to plot, plot is created. However the x-axis of plot obtained in GUI is scaled to about 40 times to that obtained by writing simple script for the same transfer function. How can I re-scale my plot?

What specifically is scaled 40X?

Doesn't seem like axis limits should be any different if the model data are the same. Have you checked for certain your GUI plot is actually the same numerically as the sample script? Perhaps you're not getting the data in that you think you are.

Can't tell anything specific w/o actual hard data/code to look at.
