Hi,

I have a confusion matrix that can be generated by the code below with attached mat-file.

figure; cm = confusionchart([trueCellR{:}],[testCellR{:}],'RowSummary','row-normalized','ColumnSummary','column-normalized');

I want to remove the class of "n/a" in both confusion matrix and generated figure.

Besides, how can I change the order of the classes in the figure?

Thank you very much,

load testCells

x = removecats([trueCellR{:}],'n/a');

y = removecats([testCellR{:}],'n/a');

x = reordercats(x,[3 2 1]);

figure; cm = confusionchart(x,y,'RowSummary','row-normalized','ColumnSummary','column-normalized');
