How to expand a waveform on x-axis?
5 views (last 30 days)
I want to expand a waveform on the x-axis. Specificlly, in the following fig, I would like to expand a waveform in such a way that the waveform from with X = 0:1 sec is expanded from x = 0:2.5. In other words, I would like to plot the waveform such that the duration from 0 to 1 sec be plotted as five big boxes, i.e., each grided box. Any suggestions would be appreciated.

MATLAB only gives control over major ticks, with it deciding minor ticks automatically. Grid lines are drawn at the minor tick positions.
So if you want grid lines at specific distance, you can set those positions as major ticks in xticks. Or you can draw the lines yourself.
Your current range is 0 to 5, so 0 to 1 is 1/5 of the space. You want 25 boxes in that space so each will take 1/25 of 1/5 = 1/125 of the width. If your axes is 750 pixels wide that would make the boxes 6 pixels apart. I don't think I see the benefit of drawing boxes that fine.
