Hello everybody,

I would like to create a heatmap in which the X-Labels are repeated. The X-Label categories are the strings "L", "M", and "R". Tried to make the strings unique by adding spaces, but it didn't work:

figure
h = heatmap(randi(100,10,12), 'Colormap', jet);
h.YData = ["E10" "E9" "E8" "E7" "E6" "E5" "E4" "E3" "E2" "E1"];
h.XData = ["L" "M" "R"
           strcat(" ","L") strcat(" ","M") strcat(" ","R")
           strcat(" ","L"," ") strcat(" ","M"," ") strcat(" ","R"," ")
           strcat("  ","L","  ") strcat("  ","M","  ") strcat("  ","R","  ")];

The error message "Vector of x values contains duplicate values" appears. Strangely enough, Matlab sees the generated strings as unique:

str = ["L" "M" "R"
       strcat(" ","L") strcat(" ","M") strcat(" ","R")
       strcat(" ","L"," ") strcat(" ","M"," ") strcat(" ","R"," ")
       strcat("  ","L","  ") strcat("  ","M","  ") strcat("  ","R","  ")];
unique(str)
ans = 
  1×12 string array
    "  L  "    "  M  "    "  R  "    " L"    " L "    " M"    " M "    " R"    " R "    "L"    "M"    "R"

Where is the mistake? Does anyone have a solution?

Best regards

Torsten

在 MATLAB Online 中打开

Instead of XData and YData, change XDisplayLabels and YDisplayLabels.

h.YDisplayLabels = ["E10" "E9" "E8" "E7" "E6" "E5" "E4" "E3" "E2" "E1"];
h.XDisplayLabels = ["L" "M" "R"
           strcat(" ","L") strcat(" ","M") strcat(" ","R")
           strcat(" ","L"," ") strcat(" ","M"," ") strcat(" ","R"," ")
           strcat("  ","L","  ") strcat("  ","M","  ") strcat("  ","R","  ")];
