How to plot a figure from a data where a parameter is within a range (not with the full range of data)

I want to plot the diagram where α (=x(324,:)) from the range (0.4, 0.9). I want to restrict α within that range. I do not want to plot is within full range of the data. How to do that?

Please suggest.
