Custom x-axis values in a matlab plot

Question

Currently when I plot a 9 by 6 array, the x-axis of the figure is just 1, 2, 3 up to 9. The Y-axis shows the correct values.

Instead of 1 to 9 I would like the x-axi

Answer 1

You should be using xTickLabel instead of XTick.

MATLAB plots every column as a seperate curve. So, that means you have 6 curves and 9 data points for each curve. x-axis data is 1-9 because you did not provide any data for MATLAB to plot with.

Furthermore, you probably want the wrong thing. Doing this will give you equal spacing. It will just replace 1-9 with your array. Since your x-axis data is not equally spaced, it will be weird.

You may want to do it like this:

xdat = [100 200 400 1000 2000 5000 10000 20000 50000];
ydat = rand(9,6); % Your y-axis data
plot(xdat, ydat)
