My Matrix 702x22, and include spectra data.
There are spectra data along the frequency at the different time.
So, the first column is frequency and the first row is time.
I want to plot gragh 2:702 row and 2:22 column.
I got the graph that I've expected except the x-axis scale.
Its x-axis scale is just numeric order, 0 to 800.
How can I change the x-axis to the frequecy value which is on the first column?
