I understand that I need to have a (in this case) square matrix with all the data. But the question now is;
- can the contourplot not interpolate the missing values or alternatively - I have fit a model to the z data (z = 100 + 0.5x + 0.5y). How can I make from this model a "square" matrix z to make a contour plot?
