Andrew, I believe this is caused by "aliasing" - a computer graphics term that refers to error/distortion introduced by rasterization or numeric rounding. It...
... OK. I looked at SVG and EPS output, and as you say they look fine. So then this is the fault of libpng and/or libgd? It's strange that the PNG and GIF...
Andrew, ploticus uses libgd to generate both PNG and GIF. I took a quick look at the GD docs (www.boutell.com/gd) and it appears that recent versions of GD do...
... OK-- I see. In this case I'd rather "snap to grid" in order to eliminate those distortions. Anyway, thanks for clarifying this. I'll see if I can find a...
One other thing I forgot to mention: thanks a lot for making ploticus. It's very capable and is really saving my butt right now. The net is full of software...

Pete, see http://ploticus.sourceforge.net/doc/times.html time values that are to be plotted must use 24 hour notation, eg 00:50:45 also, your data must be...
Hi list, I found two bugs, or better missing features in clickmap support. A attached two patches against 2.31. I don't know if they are really the right way...

Hi, ploticus version 2.32 is now available at http://ploticus.sourceforge.net Highlights of this version include new legend rendering capabilities and Venn...
I think it would be useful to have an option for anti-aliased line drawing capability. I've never done scatterplots, but I make pie charts in png format, and ...
Hi, Later versions of GD have antialiased linedrawing capability. What's needed here is an interface added to ploticus grgd.c to use the antialias linedrawing...
Is there anyway around the 500 clickmap region limit? Is there a good reason for this or could I generate the SVG and add them in my self somehow(probably not...

Hi, if you have the source code, edit clickmap.c and change #define MAXENTRIES 500 to whatever you like. Then type: make I haven't tried this myself but see...
Hi, you need to put the grid specification in the proc xaxis block where you render your value-specific stubs. See my changes below. -Steve ... // specify...
If nobody else interested, I'd be willing to give it a whirl. That assumes I can make some time, and can figure out the gd functions and grgd.c code. I'm very...
Daniel, probably the first thing that needs to be tackled is understanding how the GD feature works. Maybe we can both take a look http://www.boutell.com/gd/ ...
Sounds good. BTW - I've used gd a fair amount before. I use it to draw maps. The anti-aliasing has not been a problem for the maps. Probably because they are...
Hi, I'm trying to use -drawdump and draw.pl to generate an image, but it's not working. I've used the bars prefab to generate a gif image, then set the output ...

Kalin, the extreme width of your result probably is due to an error on your part, perhaps you are plotting values that are way out of range. if you want, send...
