Here are some examples showing the usage of <a class="xref" href="SetLegendPosition.html" title="SetLegendPosition"><span class="refentrytitle">SetLegendPosition</span></a>
|
|
|
4 |
to position the legend on the plot. The first two arguments ($x, $y)
|
|
|
5 |
indicate a point on the legend box, relative to the legend box size, with
|
|
|
6 |
(0,0) being the upper left corner, and (1,1) being the lower right corner.
|
|
|
7 |
The third argument $relative_to indicates the positioning mode: image, plot,
|
|
|
8 |
world, or title. The next two arguments ($x_base, $y_base), along with the
|
|
|
9 |
positioning mode, indicate where to place the legend point given in the
|
|
|
10 |
first two arguments. The last two optional arguments ($x_offset, $y_offset)
|
|
|
11 |
are an additional pixel offset.
