Hi,

is it possible to change the time-axis in the plot, which is created by "rpmfreqmap"? The default time-axis (yellow highlighted at the bottom of the picture) starts always from 0 second. Obviously there is no space for the input in "rpmfreqmap" to define a time-axis by users themselves. I would like to only change the scales in time-axis (e.g. starting from 5 sec and ending at 10 sec) without changing any other plottings in the picture. Is that possible? How does it work?

Thank you!

Yuantong

Hi,

You can change the "x-axis" limits of the plot obtained using "rpmfreqmap", without changing the data using the axes handle as follows:

hf = findall(0,'Type','axes'); % Gets the handle to all axes 
hf(6).XLim = [5,10];
hf(6).XTick = 5:10;
hf(6).XTickLabel = cellstr(string(hf(6).XTick));
