[Scilab-users] Format legends of a graph as a 2D table

[Rafael Guerra]

Hello Samuel,

 

Thanks for the very useful tip about the plot margins and for the elaborated
legends_multicolumn function.

 

I think it is important  to be able to place the plot legends automatically
and to have the option but not be obliged to do it manually.

 

For instance, the example below was generated automatically using the legend
command and allowing for some extra margin at the top of the plot area: 

ax.margins(3)=0.3;   // upper margin

legend(names_legend, -5);  // upper caption

The legends were chopped off but I think that with all the insight you
provided, we can adapt your "legends_mc" function in order to create a
sister "legend_mc" function; automated using the "legend" command, the width
of the legend blocks and the plot margins property,  so that we do not need
to manually position the legends outside the plots.

 

Thanks and regards,

Rafael G.

Hello,

 

One alternative to your solution which can hide a lot of the plotted data if
the legend names are big:

(figure)

is to keep the legends as short as possible by using only numbers and
placing the full text of the curve legends on the figure's title:
(figure)

Yes, it's a nice solution.

It would be important to have in plot2d the option to post the legends
completely outside the plotting area. Could we achieve this by using
subplots for instance?

it is not really the job of plot2d() to put legends, despite its leg=..
parameter.
legends() (and legends_multicolumn() on fileexchange) allow to place
the bloc of legends anywhere on the figure, without any clipping out of the
data_bounds of the active axes.
Yes, using subplot() can be helpful, or more simply increasing by hand the 
chosen margin of the axes where to put the legends:
clf, plot2d()
ax = gca(); ax.margins(2)=0.3;
