How can I match axis values with data?

Hi, my data is between -6 and 3. So I changed the xtick in order to match my values with the given plot. But I got something I was not waiting for. Here is the figure.

Mayhaps what you were looking for is xlim instead...
Need to see your code and the data to be sure what's going on exactly.

If you do not specify the X-values of the data, Matlab assume, that they are 1:length(data). Example:
data = rand(1, 10);
plot(data)
If your data goes from -6 to 3, use this as X-values:
x = -6:3;
plot(x, data)
