Hello, I have a sample file: chr22 100 150 125 21 0.145 + chr22 200 300 212 13 0.05 + chr22 345 365 351 12 0.09 + chr22 500 750 510 15 0.10 + chr22 500 750 642 9 0.02 + chr22 800 900 850 10 0.05 + where I need to generate a histogram from the data in column 6 (i.e. 0.145, 0.05, etc.). To make it easier to read, I would plot the data as 1-0.05=0.95 for all of the data in column 6. What I would like to know is how to generate a histogram with the data from one file? Also, would I be able to generate one histogram from multiple files as well (with the same format)? For example, I have multiple files in the same format as the sample file above, and I would like to make one histogram for all column six data in all files.
