I have a matrix of 9 by 5. I want to colur them in a table so that the higher values got red and the lowest got yellow. The intermediates are needed to be coloured with much less intense colours. So that i can just look into the colured table and can find the extreme values.
Here is a sample matrix
A = [0.7637612466433112,1.1142257017424961,0.2706813336848490,0.6354189964764154,30.6379671624144230,11.8049168799568474,15.7338944060010970,18.0052089219629146,1.5550130243814884

@Adam I increased the row sizes.
@Image Analyst Hm, I think so.

I also agree with Image Analyst.
Here are some possible solutions
  1. just to expand the horizontal size of the figure.
  2. rotate your matrix if there are much less columns than rows.
  3. round your values so they only have 1 decimal place - that will make shorter strings.
  4. just use the color bar to estimate the value of each cell.

Sounds like a Yair Altman question.
