About Findchangepts function X axis values.

Hi there, I am using the matlab function 'findchangepts' and it works correctly except a simple issue. It finds the maximum changes where the values goes into y axis and sample number is on x axis. Is there any way i can change the values the x axis other than sample number? Say I have X and Y values. the function finds the change in Y values but plots it against the size of Y, doesn't take X values.

Thanks in advance.

You may find ischange's 'SamplePoints' helpful, although it indicates that the input x-axis points must be sorted.
