Contour plot in python
 

Hi, I have unstructured grid data set with which I want to get pressure and velocity contours. I am using python to plot the contours. Here is the link which provided the details how to plot contours from unstructured grid data


https://scipy-cookbook.readthedocs.i...aced_data.html


I used the above mentioned method to plot pressure and velocity contours. In the velocity contour the wall region is properly visualized, whereas in the pressure contour the region is not visible, the region is filed by the color. The images are attached


Any help regarding this will be appreciatedhttp://ibb.co/F52Jqc6http://ibb.co/0tNZBm7

Can I see your code? Or is it exactly the same as at the page you linked?

If your data is unstructured you may first need to convert the scattered points to a plaid array. The scipy function griddata will do this for you. Then use matplotlib’s contourf.

However looking at your images the data looks clipped. Just adjust the contour levels.
