## For more information, use the -h option:
|
| 6 |
## ./overlayHists.py -h

## Define usage string for help option

usage="""usage: %prog [options] file1.root file2.root file3.root ...

function: overlays corresponding histograms from several files, dumping the
|
| 12 |
images into an identical directory structure in the local directory
|
| 13 |
and also merging all images into a single file (if output is pdf)
|
| 14 |
|
| 15 |
naming: histograms whose names contain certain key terms will be handled
|
| 16 |
specially. Use this to your advantage!
|
| 17 |
'Eff' : y-axis will be scaled from 0 to 1
|
| 18 |
'Norm': plot will be area normalized
|
| 19 |
'Logx': x-axis will be on log scale
|
| 20 |
'Logy': y-axis will be on log scale"""
