List of MUGL Incompatibilities

This page documents differences in the MUGL specification between the version of MUGL that js-multigraph expects, as compared to the MUGL used by older versions of Multigraph --- in particular, the Flash version. We do not necessarily need to code js-multigraph to be backward compatible to support these differences, but we do want to at least document them here.

• "dotsize" (Flash) renderer option name changed to "pointsize" (js-multigraph)
• "dotcolor" (Flash) renderer option name changed to "pointcolor" (js-multigraph)
• Flash version of Multigraph actually works with MUGL files having a section that reference a non-existent axis id, because it defaults to the first axis
• older versions of Flash multigraph had "missingvalue" and "missingop" as renderer options, rather than metadata tags in the section
• older Flash versions used a single number for the axis "position" attribute, and a "positionbase" attribute, instead of the newer position/base/anchor positioning attributes
• The current version of Multigraph recognizes only the 8 color names: black, red, green, blue, yellow, magenta, cyan, white. For colors other than these 8, the 6-char hex RGB color code should be used (with a '0x' or '#' prefix). Previous versions of Multigraph recognized a slightly larger, rather random, collection of color names.
