How can I make the top labels on the plot below vertical so they can be read and not overlap each other?

The code I used to create the plot is:

indexnames2 = {05730, Q2774, 05453, 27202, 03689, 27367, 09747, 14922,
    54785, 07884, 02659, 06749, 08731};
ticks2 = Transpose[{Range[Length[indexnames2]], indexnames2}];
MatrixPlot[outtabletoprint, ColorFunction -> "TemperatureMap", 
 FrameTicks -> {ticks2, None, None, ticks2}, 
 PlotLegends -> Automatic, RotateLabel -> True, 
 PlotLabel -> Style[seqgroupname, FontSize -> 18]]

enter image description here

  • $\begingroup$ Try ticks=Table[{i, Rotate[i,Pi/4]},{i,1,num}] $\endgroup$ – Rom38 Apr 15 '20 at 12:54
  • $\begingroup$ @Rom38 That removed all of my tick marks. I have edited my question to show how my labels are set. $\endgroup$ – Jamie Apr 15 '20 at 13:05

outtabletoprint = RandomReal[1, {13, 13}];

MatrixPlot[outtabletoprint, ColorFunction -> "TemperatureMap", 
 FrameTicks -> {ticks2, None, None, MapAt[Rotate[#, 90 Degree] &, ticks2, {All, 2}]}, 
 PlotLegends -> Automatic]
