markersize what you are trying? If so, what is the problem exactly? I think you can tune the relation of the size of the markers with the plot size to get what you want:
julia> for s in [ 10, 20, 30 ]
A very ugly workaround is the following. Plot one figure with the desired size and a symbol with
markersize=100, and save it svg, for example:
plot.svg file in Inkscape, and click on the x-axis, above you will see its width (in my case, 452.106).
Click on the circle, and see its width (diameter), in my case 181.
Therefore, a scatter circle of diameter 181 has diameter 181/452.106 in x-axis units, and corresponds
markersize=100. Therefore, to plot a symbol with diameter 1.0 you need
markersize=100*(452.106/181). In other words, set
markerunit = 100*(452.106/181)
Finally, use these units to set the scatter size:
Of course this only works if you maintain the overall plot appearance (size, legends, titles, etc), constant from the measure of sizes to the final plotting.
