Facsimile: Overlaying Histograms Help Topic
Help Index
Histograms may be overlayed from any active data source but we recommend working with files from a List.
- Select the "Plots" menu and "Histogram Overlay". A blank histogram overlay window will appear.
- Select the "Plots" menu and "Histogram".
- Select the desired parameter for display by Right clicking the axis label.
- While holding down the Crtl key drag the histogram into the blank histogram overlay window.
- In the source histogram window, Right click and select "File","Next".
- Crtl-drag this histogram onto the histogram overlay window. Note the histograms automatically normalise based on maximum peak height.
- In the histogram overlay window, Right click and select "Hist Overlay","Contour lines".
Note that it is possible to have multiple histogram overlay windows open simultaneously.
Histogram overlays are best gated adding all the plots to the desired Histogram Overlay window then applying the gate.
