How to create readable files from Matlab to Paraview to display structural deformation?

Hello,
I'm really new to Paraview, I'd like to create a plot in Paraview showing the displacement of a rectangular mesh. I use this function "vtkwrite" to export the vtk file:
I wrote this line:
vtkwrite('cantiBeam', 'polydata','triangle', xdis, ydis, z, tri);
where cantiBeam is the file name, polydata is the datatype, triangle is the element type, xdis is the deformed x coordinate, ydis is the deformed y coordinate, z is set to 0 as this is a 2d structure. tri is the connectivity.
I successfully plot this structure in Paraview like this (I used random deformation just to demonstrate):

However, I'd like to plot the deformation with colors, e.g. dark color for large deformations, for example, like in Abaqus:

I guess when creating vtk file, there needs to be the information to tell Paraview what the deformation is, but how can I do it?
Thanks!

I am surprised......why you want to go to Paraview to plot when you have MATLAB..... :|

It can be very much plotted......Check this file exchange for more details: https://in.mathworks.com/matlabcentral/fileexchange/32719-postprocessing-in-fem. Any more questions feel free to discuss.
