Hi, im trying to plot an area graph with interpolated shading, in which i use patch(). Everything works out perfectly but i'm graphing a set of datapoints that range from 4500-5500. So naturally when I put the plot range to that value it only shows one color. Is there a way to concentrate the interpolation between the max and min value points of my data?

I had to add zeroes in the beginning and end of my data vector so I could enclose the data between x axis and my value points

The simplest solution would be to change the mapping of data values to the colormap using caxis, e.g.:

caxis([4500 5500])

Ohh, now its interpolated again. Is there a way to concentrate the color so that patch stays blue until about 4000 or so and then starts interpolating?

Perhaps the easiest approach would be to tweak the colormap using the colormapeditor. The documentation also describes how you can save the colormap after you have edited it.
