Geometry of significance map works, but somehow values are overprinted.
Might be due to wrong matrix generation.
Plot works, problem was iteration of columns and rows. Solved by generating iteration directly in significance Matrix.
Problem: Significance matrix is not symmetrical, cannot be used yet.
Works in general, but NaN or zero values throw division by zero error
In case of ZeroDivision, print '!' instead of asterisks.
Written very unelegantly...
Textsize larger
Removed Bug shifting the column -1: "Medium" sample had to be excluded
Removed 'n. s.' from matrix
Color-coded significances
