In the code below, how to make PlotLabel automatically show the name of the data sets (i.e., aa, bb, cc)?

aa = RandomReal[1, {5, 5}];
bb = RandomReal[1, {5, 5}];
cc = RandomReal[1, {5, 5}];
Table[MatrixPlot[data, PlotLabel -> ?? ],{data,{aa,bb,cc}}]

  • $\begingroup$ Row[MapThread[ MatrixPlot[#1, PlotLabel -> #2] &, {{aa, bb, cc}, {"aa", "bb", "cc"}}]] ? $\endgroup$ – Xminer Oct 20 '19 at 20:16
  • $\begingroup$ @Xminer Thanks, but this does not extract the names automatically. $\endgroup$ – xiaohuamao Oct 20 '19 at 20:26

Table[MatrixPlot[First @ data, PlotLabel -> data],
    {data, Defer /@ Unevaluated[{aa, bb, cc}]}]

enter image description here

Table[MatrixPlot[ReleaseHold @ data, PlotLabel -> data], 
     {data, HoldForm /@ Unevaluated[{aa, bb, cc}]}]
