Hi, I encountered a question in ListContourPlot and am writing for help and
advice.
I have two sets of data, which have different ranges in x- and y-. (Say, one
set of data is from {{-4,4}, {-3,0}}, while another set is from {{-1,1}, {0,
1}}) and the z value for the first set is from, say, 0 to 100; while the z
value for the second set is from, say, 0 to 20.
When I do
ListContourPlot[data1]; ListContourPlot[data2]
both plots have the shading from black to white, but apparently the white
regions corresponding to very different z value! (in first plot, white
corresponds to (roughly) 100 while in second set it's about 20!) The problem
here is that both data sets have different x- and y- range so I cannot
combine them to get one big data set.
I was wondering if there's a way to "change/downgrade" the shading of the
2nd data set? So that the shading of the contour plot of the second data set
so the shading can be used to compare with the contour plot from the first
data set?
I'd also appreciate any suggestions on better ways to present the plots.
Thanks for your time in advance.
Sincerely,
JT
