<div class="markdown_content"><p>I've wondered for a while now what the limitations are for implementing such a feature. I've found an extraordinarily convoluted work-around online (<a href="http://www.gnuplotting.org/object-placement-using-a-data-file/" rel="nofollow">http://www.gnuplotting.org/object-placement-using-a-data-file/</a>), but I believe the utility of the feature is sufficient to ask that this be part of core gnuplot functionality. The idea is as follows: say the user has a set of coordinates that describe a polygon, and they want to use this as their point type in a plot. This could be done using the "set object &lt;index&gt; polygon..." command. Then in the script type</p> <p>plot sin(x) w polygon &lt;index&gt;</p> <p>and the polygon object would be placed at the points specified by sin(x).</p> <p>Additional parameters: the data could be read in like "with ellipses" currently are, in which the third column (major axis) and fourth column (minor axis) determine scaling in x and y, and fifth column (angle) rotates the polygon after scaling.</p></div>
