I'm trying to plot a heat map with fold change (log2 values) values ranging from almost -100 to 100 across 6 time points. There are actually very few points in the extreme ranges of fold change. I was planning on plotting just the -10 to 10 range in the scale with differing color intensity where as the points above or below that will be color coded in a single color. I tried using breaks with (-100,-10,-5,0,5,10,100) but in the legend the color code for -10 to 10 range is not visible. Can you please suggest any other solution. I've been looking for it everywhere but haven't found a solution. I would really appreciate your help. Thanks in advance!
