Hi!
I recently started using wxmaxima to make graphs.
One problem I keep having is that I can not figure out how to tell maxima to
use my numbers on the xy axis.
For example this:
wxplot2d([2*x-1], [x,-4,5],
[gnuplot_preamble, "set grid;"])$
That would give me:
X axis: -4 -3 -2 -1 0 1 2 3 4 5
Y axis: -10 -8 -6 -4 -2 0 2 4 6 8 10
This is OK for me, but when I do this:
wxplot2d([2*x-1], [x,-5,5],
[gnuplot_preamble, "set grid;"])$
gives me:
X axis: blank -4 -2 0 2 4 blank
Y axis: -15 -10 -5 0 5 10
That output makes it a lot harder to see exactly where I can get 'whole'
numbers.
So the question is: How can I choose what XY numbers should be displayed for
each axis? (Half numbers would be a nice bonus)
I can live with Y skipping a couple numbers, but I really need to be able to
control X.
Another question I have is: Is there a way to highlight where X meets Y in
the graph?
In my example -2x meets -5y, but I also know that 0x meets -1y and 1x meets
1y. If there is a way to put a circle or a dot there, I'd like to learn how.
I did this using wxmaxima 0.8.3 on windows, but I will mainly be using
wxmaxima 0.7.1 with maxima 5.13.0 on ubuntu linux.
Thanks in advance, hope I did this mailing list thing correctly :-)
