legend — draw graph legend
hl=legend([h,] string1,string2, ... [,pos] [,boxed]) hl=legend([h,] strings [,pos] [,boxed])
graphic handle on an Axes entity or vector of handles on
polyline entities. The default value is the handle on
current_axes.
character strings stringsi is the legend of the ith curve
Starting from Scilab 5.2, it is possible to write LaTeX or MathML expression.
n vector of strings, strings(i) is the legend of the ith curve
Starting from Scilab 5.2, it is possible to write LaTeX or MathML expression.
(optional) specify where to draw the legend; this parameter may be a integer flag (or equivalently a string flag) or a vector [x,y] which gives the coordinates of the upper left corner of the legend box. In the first case the possible values are:
the legend is drawn in the upper right-hand corner (default).
the legend is drawn in the upper left-hand corner.
the legend is drawn in the lower left-hand corner.
the legend is drawn in the lower right-hand corner.
interactive placement with the mouse .
the legend is drawn at the right of the upper right-hand corner.
the legend is drawn at the left of the upper left-hand corner.
the legend is drawn at the left of the lower left-hand corner.
the legend is drawn at the right of the lower right-hand corner.
the legend is drawn above the upper left-hand corner.
the legend is drawn below the lower left-hand corner.
a boolean (default value %t) which sets ot not the drawing of the box.
a handle, points to the Compound containing all the legend .
Puts a legend on the current plot using the specified strings as labels. legend prepends labels by a recall of the corresponding line or patch. The recall type and properties are recovered from the given handles:
when called without handle argument (or with a handle on a axes entity) the function first build the vectors of handle on polylines entities which are the children of the given axes.
In the interactive placement mode (opt=5) move the legend box with the mouse and press the left button to release it.
