mouse manual option only so far

To answer one of your questions. I believe the output plot size has been a request for users for some time. There have been a few posts asking how to change the size of a plot using code (which would be very nice).

Unless someone has been clever enough to find a way to do it, I think your stuck with standard plot output sizes.

plot/options

You should take a look at ?plot/options, in particular at the third example given on that help page.

What are the exact commands you are using?

Hi RNiven,

If I do

plotsetup(eps, plotoutput="temp.eps", plotoptions="axiswidth=10,axisheight=500");      
plot(x,x=0..1);

I get a plot that is very skewed, so certainly something is affected. This is on linux, not on mac, admittedly. ImageMagick identifies the full image, including margins, as being 624x38; I ran identify temp.eps from the linux command line to obtain that info. Specifying other sizes leads to numbers that seem correct as well. What is the exact command you are running that do not seem to have an effect?

I think that dual axis plots are not supported on all plot devices; this is documented on the ?plots/dualaxisplot page. (The last line of the Description section.) I'm afraid you don't have a lot of options there, sorry.

Hope this helps,

"Not everyone wants to use a mouse!!!! - automatic generating is more useful." gets a thumbs-up.

Thanks Erik

Here's an example, which does not change the output graph at all (Maple 13.02, MacBook Pro, Mac OS X 10.4.11)

restart;
Q_pts_deg := [-180, 0], [-150, -2.158772567*10^20], [-120, -4.317529030*10^20], [-90, -6.476269881*10^20], [-60, -7.677036966*10^20], [-30, -5.102018370*10^20], [0, -3.385247329*10^14], [30, 5.102018205*10^20], [60, 7.677036722*10^20], [90, 6.476270518*10^20], [120, 4.317506276*10^20], [150, 2.158749517*10^20], [180, 0.];

truncated code

The website seems to be truncating the code lines above; contact me on r.niven@adfa.edu.au for source code.
