2007-02-10 Thread David Joyner
Not wanting to suggest I am the expert on this, I would conjecture that splitting the plot in two parts is the right way to do it. The reason why I think that is because it seems reasonable to me that plot cleverly concatenates lots of line plots. If true, it is the interpolation of the point (-1,

Before doing your own coding, you might look at plot/axes.py. There are no examples and I'm not sure it will help you, but it seems related to what you want. On 2/10/07, Joel B. Mohler <[EMAIL PROTECTED]> wrote: > > Now that I've more thoroughly read the reference manual and understand more > the

Now that I've more thoroughly read the reference manual and understand more the logical structure of how to do thing, I'm even more impressed with the plotting. One question lingers though: Is there any way to include gridlines with-out coding my own? I've been enraged at maple for not suppo

[sage-support] a plotting question

2007-02-10 Thread Joel B. Mohler
I spent some time trying to make a pretty plot for my calculus quiz -- a plot of y=1/x. Ideally, I wanted a plot from -4..4 with range -4..4. Unfortunately, the plot command calculates the range intelligently and I could find no way to modify that behavior. Did I miss it? I must say that I
