From this precedent question Drawing a large binary matrix as colored grid in TikZ I have the following matrix plot:

which plots a 50 columns matrix:

enter image description here

I would like to add a number to each row of the matrix

0.0293
0.0211
0.0165
0.0163
0.0134
0.0382
0.0150
0.8501

and (aligned) add a matrix plot of one row at the bottom with white (0) to black (1) indicating these weights.

0.2833
0.0336
0.7766
0.0468
0.0228
0.0143
0.6877
0.0700
0.1287
0.6659
0.7123
0.0143
0.0143
0.6325
0.8049
0.7282
0.1624
0.6346
0.0564
0.0176
0.0143
0.0271
0.6463
0.7268
0.4798
0.1637
0.0297
0.3054
0.5039
0.0246
0.7140
0.3091
0.4256
0.3418
0.6493
0.0508
0.0143
0.2927
0.0291
0.6622
0.0143
0.0177
0.1610
0.1287
0.7471
0.0563
0.0143
0.3275
0.6773
0.5992

to get something like this:

enter image description here

(I have not completed the 1-row matrix of greys)

To distinguish better the rows and columns it would be a feature of the plot to control the white separation lines of the matrices.

Please note that the figure is a bit too wide for the given page parameters, meaning that you may want to make the page wider, the figure smaller or to rotate the figure.

  • Thank you. I would like to test both alternatives, reduce the size and make it in one page (without other floats or text) rotated 90. I noticed that the figure is not centered with the words Figure 1: caption. Do you know how to arrange it?. – user1993416 Apr 11 at 16:30
  • @user1993416 I already upvoted it. – user121799 Apr 12 at 16:15
