|
|
* PlotDedxScan.C
|
|
*
|
|
* Builds the comma-separated file/label lists make_pretty.C's
|
|
* multi-file overlay function expects, straight from your
|
|
* DEDX_SCALE scan -- so you can superimpose every scale's histogram
|
|
* for a given gate (a1c2fix, a1c1c2, etc.) in one call, without
|
|
* typing out each file path and label by hand.
|
|
*
|
|
* Only load THIS file -- it already #includes make_pretty.C.
|
|
*
|
|
* Usage:
|
|
*
|
|
* .L PlotDedxScan.C
|
|
** std::vector<double> scales = {0.70, 0.75, 0.80, 0.85, 0.87, 0.90, 0.92, 0.95, 1.00, 1.05, 1.10, 1.15};
|
|
* PlotDedxScan(scales,
|
|
* "_m27Alax+misc_sx3_p/m27Alax_Ex_from_p_a1c1c2_sx3");
|
|
*
|
|
* // or for the a1c2fix gate:
|
|
* PlotDedxScan(scales,
|
|
* "_m27Alax+misc_sx3_p/m27Alax_Ex_from_p_a1c2fix_sx3");

// scales : the DEDX_SCALE values from your bash scan, e.g.
|
|
// {0.70, 0.75, ..., 1.20} -- MUST match your folder
|
|
// names exactly (same decimal formatting), since each
|
|
// path is built as folderPrefix + scale + "/" + fileName
|
|
// histPath : histogram path inside each file (same for every
|
|
// scale), e.g. "_m27Alax+misc_sx3_p/m27Alax_Ex_from_p_a1c1c2_sx3"
|
|
// folderPrefix : e.g. "Output_27Al_"
|
|
// fileName : ROOT file name inside each folder, e.g. "output_27Al.root"
|
|
// xlabel,ylabel: axis titles for the overlay plot
|
|
// xMin,xMax : x-axis zoom range -- set these to the region where your
|
|
// peaks actually live (e.g. -3, 9) to cut out the flat,
|
|
// empty tails and make the overlaid curves easier to read.
|
|
// Leave at -9999 for the full auto range.
|
|
// yMin,yMax : optional y-axis range; leave at -9999 for auto
|
|
// canvasW,canvasH : output image size in pixels. Defaults here (3000x2100)
|
|
// are larger than make_pretty.C's own defaults (2100x1575)
|
|
// since a busy multi-curve overlay benefits from the extra
|
|
// resolution -- especially once zoomed in with xMin/xMax.
|
|
// maxOverlay : if scales.size() exceeds this, evenly subsample down to
|
|
// maxOverlay curves (always keeping the first and last)
|
|
// rather than plotting everything -- past ~5-6 overlapping
|
|
// histograms in the same narrow x-range, more curves stops
|
|
// helping and just makes the plot harder to read regardless
|
|
// of resolution. Set to 0 to disable subsampling entirely.
