I used d3heatmap and scales packages in R to make heatmaps of my data. Everything looks fine except the fact that it does not show color key to indicate the scales for each color. For example; that the red is a certain values and the same for orange and yellow (as a range).....
Any idea hoe I can add the color legend to my heatmap?
I really like the d3heatmap as you get kind of interactive heatmap with some cool future, but experience with oder packages are also welcomed!
