FypML Version 9

Applicable to: DataNav versions 3.1.1 (26 Nov 2008) through 3.1.7 (18 Mar 2009).

• • One new element, zaxis, representing the third dimension in a graph. It is a required component of a graph node, and it must be the third element listed in the graph's element content. It controls the color-mapping properties that determine how any and all heatmaps are rendered in a graph. Formerly, the heatmap element itself had an attribute (cmap) that selected one of six possible color maps. Now it gets all color-mapping information from the parent graph's Z axis: the color map itself, the mapped data range (start and end attributes), and the mapping mode (the new cmode attribute). All heatmaps in a single graph are now rendered using the same color-mapping properties. As with the primary and secondary axes, the zaxis may be rendered; the rendering includes a gradient bar depicting the content of the color map, alongside the typical axis line with optional tick sets that depict the data range spanned in this "Z" dimension. The zaxis has all the same attributes an axis node except the units attribute; additional attributes include the cmap and cmode properties, plus gap (distance between gradient bar and nearest edge of graph window), size (gradient bar width), and edge (the graph window edge alongside which the Z axis is drawn).

  • Removed cmap attribute from the heatmap element.

  • In schema version 7, the axis element was modified so that it no longer restricted the number of tick set children it could contain. However, schemas 7 and 8 still enforced the upper limit of 4 tick sets, established in schema version 0. The restriction is relaxed in this version.
