Loading multiple datafiles into MATLAB and plotting a colourmap

2 views (last 30 days)
Hi,
I have x data and y data for each value of z data. That is for each z-value I create a xy plot. I want to import all the xy plots for each z value to the matlab, remove the outliers in the xy plot for each z-value, and plot a colourmap with x-axis being the x-values and y-axis being the z-values and y being the colour intensity.
Can someone please help me in this ?
Thanks in advance.

In Matlab, the command "colormap" corresponds to the color/colours that are assigned to the intensity of a figure. You display 2D data with intensity values coded as colour with "imagesc" as well as other commands, for example:
[x,y]=meshgrid(1:10,1:10);
imagesc(x)
colormap(hot)
and
imagesc(y)
colormap(bone)
Different to imagesc and colours you can also display meshes, surfaces or many other options, and still can use colours:
mesh(x);colormap jet
surf(y)
Hope this helps you solve your problem
