PlotCorrelations

Plot a correlation matrix. The value of the correlation will be color-coded and additionally printed onto each cell of the 2D plot.

Usage:

# correlation plots with 5% cutoff
+PlotCorrelations.asimov.medium {
  +HWWRun2GGF {
    <outputFile="workspaces/run2-ggf-$(fitLabel)/correlations-asimov-medium.pdf">
  }
}
+PlotCorrelations.observed.medium {
  +HWWRun2GGF {
    <outputFile="workspaces/run2-ggf-$(fitLabel)/correlations-observed-medium.pdf">
  }
}
@PlotCorrelations.*.medium/? {
  <blacklist={"mu"}>
  <whitelist={"gamma_*"}>
  <cutoff=0.05>
  <style.showNumeric=true>
  <style.numeric.textSize=0.25>
  <style.textSize=0.01>
}

The name of the output file can be determined with the outputFile tag. The source of the correlation matrix is identified with the fitresult tag. Some additional options exist to control the styling:

• orientation="up"/"down" choose whether the diagonal should be pointing up or down
• blacklist: List expressions matching parameters that should not be included
• whitelist: List expressions matching parameters that should be included, even if also matching the blacklist
• cutoff: Numeric value of the minimum correlation to be plotted. All rows and columns not including any entry above this value will be dropped.
• writeCorrelations.outputFile="filename.txt", writeCorrelations.threshold=0.6: Write all entries of the correlation matrix exceeding a given threshold to a log file for further studies.
• style.showNumeric Set to false to suppress numbers printed on cells. The text size of the numbers can be controlled with style.numeric.textSize.
• style.textSize : Set the text size of everything on the canvas.
• outputFile.csv, outputFile.plain: Give filenames to also print the correlation matrix to a CSV or plain text file.
• style.canvasScale: Control the scale of the canvas.
• style.color.divisions: number of steps for the Z (color) axis
• style.color.textSize: font size for the labels ofthe Z (color) axis
• style.marginScale,style.marginScale.top,style.marginScale.bottom,style.marginScale.left,style.marginScale.right: Control the scale of the margins.
