Schema Version 22

Post date: Oct 18, 2016 11:34:50 PM

Applicable to: DataNav version 5.0.1 (Oct 2016) through 5.0.3 (TBD 2017)

• • Introduced new schema element, contour, that replaces the now-deprecated heatmap node and offers support for contour plots. Four display modes are offered. The heatMap mode reproduces the functionality of the old heatmap node; other modes include levelLines (color-mapped contour level-curves at levels specified in the levels attribute), filledContours (bands between iso-curves are color-mapped, and level-curves are drawn in node's strokeColor); and contouredHeatMap (level-curves superimposed over heat map image).

  • (As of V5.0.2) Introduced support for translucent color (neither opaque nor fully transparent). The fillColor and strokeColor properties, as well as the color of a solid bkgFill, can now be assigned an 8-digit hex string "AARRGGBB", where the first two hex digits specify the value of the color's alpha component (FF = opaque, 00 = transparent). The fill colors for data groups in bar, pie or area charts may also take this form. The only other color attribute, cmapnan, must be opaque; if its value is an 8-digit hex string, the alpha component must be FF.

  • (As of V5.0.2) The raster node was updated to include two new display modes, pdf and cdf. In addition, optional attributes were added to explicitly define the sample range [start, end] over which a histogram is binned in the histogram, pdf, or cdf display mode. If start >= end, the actual sample range is used, which is how the raster node worked prior to this change. Since the default value is 0 for both start and end, existing figures are not impacted by the change.

  • (As of V5.0.3) A new boolean attribute, stemmed, was added to the scatter3d node. If true (the default), stem lines are drawn from each data point to the stem base plane. Otherwise, the data points are connected (in the order listed within the data set source) by a piecewise continuous trace line. Since the default value is true, existing figures are unaffected by the change.
