Hello,

I'm currently working on a project where I read data from a xlsx file and put it directly into C# or with the aid of a dataset.

After this I need to draw a Graph/Chart wich is called a contour Chart.
The data that I will be using will be of engines, heat, rotations, electricity...

I've been searching the internet for a good example/library to use, but could not find any or is paying.


Does anyone have any experience on the matter?

Thank you very much

this is an example of how the chart would look:
