Applicable to: DataNav versions 3.2.0 (30 Sep 2009) through 3.5.4 (08 Dec 2010).
Added two new stroke-related properties as inheritable styles: strokeCap and strokeJoin. These expose the stroke endcap and join styles which, prior to this change, were always "butt-ended" and "mitered join", respectively.
Changed the values of three of the "synonyms" for the strokePat attribute: dashed = "30 30" instead of "99 50"; dashdot = "30 30 10 30" instead of "99 50 10 50"; and dashdotdot = "30 30 10 30 10 30" instead of "99 50 10 50 10 50".
(22 Mar 2010, app v3.4.0) Added optional color attribute cmapnan to the zaxis ("color axis") element. This specifies the opaque RGB color to which any ill-defined datum (NaN or infinity) is mapped when rendering a heatmap in the parent graph. This "NaN color" replaces the entry at index 0 of the selected color map (cmap), so ill-defined data are mapped to colormap index 0, while well-defined data are mapped to the index range [1..255]. In prior versions, in the onscreen rendering of a heatmap, an ill-defined datum was mapped to a transparent pixel, but this was never implemented in the Postscript rendering. Rather than support transparency in Postscript (LL3 required), we decided to make the onscreen rendering opaque. Note that this change did not require a new schema version.
(07 May 2010, app v3.4.2) Added boolean attribute smooth to the heatmap element. Prior to v3.4.2, smooth interpolation of the heatmap image was always enabled, but some users didn't want it because it can be misleading -- suggesting a smoothness in the underlying data that does not exist. This attribute was added so that users can now turn off smoothing. Since the attribute is optional, it was not necessary to increment the schema version upon making this change. If the attribute is not explicitly specified -- as will be the case for all existing schema 10 documents prior to this change -- it defaults to true.
(09 Jun 2010, app v3.4.4) Added two additional options, jet and reversejet, to the enumerated attribute cmap of the zaxis element.
(08 Dec 2010, app v3.5.4) Added boolean attribute avg to the raster element. Prior to this change, the histogram display of a raster node reflected the total counts per bin across the raster collection (avg == false, the default). Now, if avg== true, the histogram reflects the average counts per bin (total divided by the number of individual rasters in the raster collection).
