I am trying to make a very simple heatmap. I have a double entry table, with header and row of the same size. The value of this table represents what I want to visualize. A twbx is attached with a copy of these data (and a csv too). I have tried to pivot the table as I know that tableau works with that kind of table, however, I am not able to make a text table with a gradient color that follows the values. Anyone can help?
I managed to put the numbers, however, I cannot color them, and I am not able to put the correct header on the other axis.
