s = Import[“Desktop/tension.xlsx”];
ListContourPlot[s, Contours → 10, PlotLegends → Automatic]
In fact, it is a contour of a circular part from (2,0) (4,0) to (0,4) (0,2).
However, I cannot get a contour on a sector of a circle.
It has redundant part
How can I delete that red part to make it a sector of a circle??
Thanks a lot!!!
Draw a white disk above the disliked area as follows
In[1]:= s = Import[FileNameJoin[{NotebookDirectory[], "..", "Abt_skrot", "tension.xlsx"}]];
In[8]:= Show[{ListContourPlot[s, Contours -> 10, PlotLegends -> Automatic, DisplayFunction -> Identity],
Graphics[{White, Disk[{0, 0}, 2, {0, \[Pi]/2}]}, DisplayFunction -> Identity]},
DisplayFunction -> $DisplayFunction, AspectRatio -> 1]
to see
Ask yourself whether this graphics is cheating because the shown inner boundary does not fulfill any boundary condition, right?
