Hi Guys

Please I have plot the follwing graph.

The graph includes three different signals (i.e. 1, 2, and 3) .

by the way this signal represent the data of the first column of the attached file (Plot_Data.csv)

I’m wondering if we can draw each signal part in different colour!!

For example, black colour for part 1, red colour for part 2, etc.

I have attached the data

Hi,

A simple solution would be to plot the data always partially.

    plot(Data(1:N1,1),Data(1:N1,2),Data(N1+1:N2,1),Data(N1+1:N2,2),Data(N2+1:end,1),Data(N2+1:end,2))

Assuming N1 and N2 are your breakpoints and Data first column is X data, and second column is Y data, you can fill in the rest.
