[sage-support] **legend

[Henri Girard]

Hi,

I have params=dict() which works well, I am trying to look the same way 
with lgd= ? like lgd=dict...something ?


I didn't find answer

This way works but I have to put a variable (q, here) but when I change 
it can change too ?


q.set_legend_options(loc=2,font_size=6,shadow=False,
 back_color="lightcyan")

show(q,**params)

If there is way ? Bienvenu :)

Regards

Henri

[HG]

Hi,
I don't see this oportunity anywhere in tuts.
That's how I used it below but now (sage-6.9/6.10beta1) it doesn't work 

legend_opts = { 'back_color': 'salmon', 'shadow': False,'fancybox': 
'True','fontsize': '6','loc': '1','borderaxespad': '1'};
O.set_legend_options(**legend_opts);

Any help
Regards
Henri

Hi,
Sorry I mistaken : Your suggestion does work but apparently some 
commands don't work.

I am trying further...
Thanks

   it would be easier to put all in a command ?

The same syntax should work:

   legend_opts = { 'back_color': 'white', 'shadow': True }

   p.set_legend_options(**legend_opts)

It doesn't work ... It seems to be a matplotlib options which I can't 
use inside texmacs directly.

Strange that **params works and not **legend.

I forget to say I can't use the show command because the plot is 
external in a texmacs session,

this one should work I try it.

Re: [sage-support] Legend label problem

[D. S. McNeil]

This seems to work on test.sagenb.org (5.0.beta1) and the 5.0.beta4 I
have around, so something (whether Sage-side or matplotlib-side) must
have changed for the better from 4.8.  Is it time-sensitive enough to
track it down and make a backpatch?

[sage-support] Legend label problem

[kcrisman]

Compare

plot(e^(-x/10),(x,0,20),legend_label='$%s$'%latex(e^(-x/10)))

AttributeError: 'Kern' object has no attribute 'height'

with

plot(e^(-x/10),(x,0,20),legend_label='$%s$'%latex(x))

(all is well).

This does not happen with e^-x.

Any ideas?  This came up while preparing a talk, unfortunately.
Presumably we haven't had enough people using legends yet for this to
come up...

Thanks,
- kcrisman

I don't think you have those methods.  I think you're using an old
version of sage (maybe <= 4.5.2?) but reading documentation from a
later version, which occasionally causes trouble.  What does version()
report?

[sage-support] Legend Options in 2D Plots? Title Options in 3D plots?

[Mel]

I have two issues:

1 - On 2D plots, I have been unable to use the legend() attribute and
the set_legend_options() attribute.

The commands
g = plot(x)
g.legend()
give me the error "AttributeError: 'Graphics' object has no attribute
'legend'"

Also, I have been unable to label the legend when creating the plot as
is shown in the sage documentation. The command
P = plot(sin, legend_label='sin')
gives me the error "RuntimeError: Error in line(): option
'legend_label' not valid."


2 - On 3D plots, is there a way to create a legend or title? Is there
a way to add labels to the axes, or change the color of the axes?

Any suggestions are welcome. Thanks!
