How do you edit the x-axis, but not change the scale of the graph/2D image on Matlab?

I have a time spatial 2D graph, and currently the axis is 1-101. However I need to change these values so it -0.0005 to 0.0005; however when I change put these values in the X limits, the graph just goes to -0.0005-0.0005 and cuts out all the data.

I would just like to change the x-axis data values independent of the graph. If this makes sense?

You would need to change the XTickLabels of the current axis. You can do this by modifying the XTickLabel as seen in the example below:

plot(1:5)
set(gca,'Xtick',1:5,'XTickLabel',{'7', '8', '9', '10', '11'})

You should change the ticklabels of the axis (that is, the strings that are shown for the ticks), not the axis values.

Alternatively, you can re-scale the image (for example, specifying x and y vectors in the imagesc() command.

edit: see here for an example: http://www.mathworks.nl/help/matlab/creating_plots/setting-axis-parameters.html#f6-27790

search in the page for: "You can adjust the axis tick-mark locations and the labels appearing at each tick mark."
