Updates to Dec 2nd 2001

Markers – early escape if marker array is null. Can happen if all values are ‘missing’ so there is nothing to plot. VML, SVG and PDF fixed.

Markers – circles were incorrectly placed if the chart had been scaled. This caused the ‘nodes’ in response surfaces to miss the intersections of the mesh. Resp2 is a good example and looks much better now!

svg,pdf – special-case for 360-degree pie wedges which are now drawn as simple filled circles without the vertical line to 12:00.

svg.initpage – uses left argument to allow arbitrary SVG to be bundled. This permits the use of ch.Include to pass in gradients and filters as text. See examples Gradient2 and FilterEffect for some possibilities.

svg.ToHEX – leave ‘&’ alone when followed by ‘#’ which allows embedding of web-style ‘ strings into headings. Essential for Unicode strings with things like chinese characters in them. Function Chinese tests it.

svg.stroke – should scale the built-in dash patterns relative to the line- weight. Fixed. Also we need to work out how to apply filters to lines!

svg.pT – uses SVG attribute ‘CrispEdges’ for collections of lines which are either horizontal or vertical. This crisps up axes and tickmarks, but leaves piechart spiders alone.

svg.pB – all bars get ‘CrispEdges’ now as these definitely look better if the anti-aliasing is turned off.
