Symbol density depends on the density of points. But it depends on the algorithm used and the type of function. I'm using the marching squares algorithm that generates a set of segments on the grid cells. Each segment - two points at the ends of the segment. More cells - more points, and hence more symbols. The segments are drawn independently each other.Thanks for the explanation. I was not asking for an arc length based marker spacing, just plotting e.g. every other or every third point. This still would not be ideal (non-equidistant markers, mismatch in closed loops) but would provide control over the average density without being forced to set the base grid too coarse. One might, of course, argue if the result would be worth the effort.mkraska attached the following image(s): Martin Kraska Pre-configured portable distribution of SMath Studio: https://smath.com/wiki/SMath_with_Plugins.ashx

The only way out would be to identify segment chains. That could perhaps provide benefits (half the number of points) but would not be for free, neither in terms of coding, nor in terms of performance.

In older versions had a problem with redrawing the region when the mouse moves. Andrey wrote about it: "RegionHolder improved to avoid excess invalidation on mouse move;". If the majority of users will use the night version and newer, I will fix this problem. Russia ☭ forever Viacheslav N. Mezentsev

Remaining problems: undefined values handling, mouse interaction (I have to press a key (any, except ctrl or shift) while dragging the plot contents. I guess that this is not by design. Don't know if that is similar to kilele's problem (can't display his screen cast).Also, independent zooming of x and y would be highly welcome, similar to the built in region (and a hotkey for setting aspect ratio to 1)I use 4875 (never saw the version 4871).

This works, unless you try to enlarge the plot above a particular level.This is reproducible. If you reduce the size, then the plot re-appeares, make it a little larger, it disappears again. In the screenshot there are two regions of different size, the smaller works, the larger does not.mkraska attached the following image(s): Martin Kraska Pre-configured portable distribution of SMath Studio: https://smath.com/wiki/SMath_with_Plugins.ashx 1 user thanked mkraska for this useful post. on 15/05/2013(UTC)

Currently, even leaving the region will not trigger update of the plot.Edited by moderator 16 May 2013 01:44:28(UTC)  | Reason: Not specified Martin Kraska Pre-configured portable distribution of SMath Studio: https://smath.com/wiki/SMath_with_Plugins.ashx
