Dear Science Working Group,
Sorry to bother you again, but your
advice on jzy3d was excellent, and we again have a question
that you might be able to help with.
Our users keep asking for publication
quality plotting (2d rather than 3d this time). Now to me
this means SVG/PDF/EPS, at the full resolution of the data.
We currently use the Nebula XYGraph, and
have an export to SVG (I think using some old Graphiti code
to bridge to the SVGGraphics2D in batik), but it is rubbish.
I think this is because XYGraph’s line trace downsamples the
data, so that it doesn’t draw to the same pixel twice, but
also because the trace directly uses the draw2D graphics
drawLine to draw directly to the screen in pixel
co-ordinates, not to the co-ordinate frame of the graph.
This gives us an SVG that looks little better than a bitmap
(see attached screenshot from inkscape, inset shows what
zoomed in data should look like).
I know many people on here use SWTChart,
does anyone know if this is likely to suffer the same issue?
Does anyone have any other suggestions of a swt-compatible
plotting library that might better support SVG export?
Kind regards,
Jake
