[Gnuplot-info] Shifting Plots on y-axis with units?

[Nicholas P. <nic...@gm...>]

Does anyone know if gnuplot has the ability to shift plots on the y-axis,
perhaps keeping association with the units?

For instance, if I have multiple sets of data with the same x-range that
appear to correlate in the graph, with different y-axis ranges (which would
place the individual graphs at much different vertical positions), how can
I shift each data set graph to coincide with the others on the vertical
y-axis?

One could think of an example as having different stock tick symbols and
finding a way to shift each individual's symbol graph on the y-axis so one
can compare the trends/spikes easier.

Thanks

@Nicholas

From your description it seems plausible you refer to /stacked plots/.  Have a
look on gnuplot's example gallery, section «page layout», entry «multiplot
layout»

https://gnuplot.sourceforge.net/demo_5.2/layout.html

examples four and five.  If I recall correctly, «Gnuplot in Action» by Philip
Janert (Manning Publications) equally describes the stacking curves for the
simultaneous presentation of multiple time series, in one of the later
chapters.  On occasion, it equally is a valuable technique for the visual
comparison of 2D histograms in a column in common if both plots share the same
over all interval, bin size, etc.  (Of course, you have the distributions
mean, median, kurtosis, skewness, etc. as a numeric tool.)
