[ferret_users] multiple property-property plots in a single figure

[Keith Lindsay <klindsay@xxxxxxxx>]

Hi,

I'd like to plot multiple property-property plots in a single figure and 
would like to avoid having to manually set axis ranges. I can't figure 
out how to do this.

For example, suppose A & B are expressions that I'd like to plot against 
each other and I'd like to combine the plots from multiple datasets into 
a single figure.

plot/vs/d=1 A, B
plot/vs/d=2/over A, B
plot/vs/d=3/over A, B

A typical situation is that the different datasets are output from 
different model simulations.

However, if the range of A and/or B in d=2 or d=3 exceeds the range in 
d=1, then I miss out on some points.

One solution is to hard code axis ranges with known 'reasonable' values. 
I'd like to avoid this because I then need to generate the ranges and 
resulting script is not easily transferable when looking at other 
expressions.

Another solution is to compute, with ferret, min's and max's of A and B 
over each dataset and take the corresponding min and max over the 
datasets. This leads to rather bulky code.

I'm wondering if another ferret user has found a simple way to do this 
that I haven't been able to come up with.

Thanks, Keith
