Description

SetLegendWorld lets you position the legend on the image, using world coordinates, rather than letting PHPlot position it for you. (World coordinates are the coordinate space of your data points.)

Parameters

Notes

The default behavior is for PHPlot to position the legend in the upper right corner of the plot area.

See SetLegendPosition for more flexible legend positioning options. SetLegendWorld($x, $y) is equivalent to SetLegendPosition(0, 0, 'world', $x, $y). This places the top left corner of the legend at world coordinates $x, $y with no pixel offset.

See also SetLegendPixels.

This function will not work with pie charts, because they have no valid world coordinates.

History

This function did actually work with pie charts through PHPlot-5.5.0, although we are not sure what it did, since pie charts do not have valid world coordinates.

Through PHPlot-5.0rc3, it was required that the data array, axis types, and any other setting which affects the scale of the data be set up before this function is used. Starting at PHPlot-5.0.4 this is no longer required, as the coordinates you supply are not scaled until the plot is drawn.
