''New to [[Analytica 5.2]]''

Use this function from the [[OnGraphDraw]] attribute to plot a solid fill between symmetry percentiles in a probability bands result view.

== Plot solid prob bands (canv, info, roles'', transparencyMask'') ==

Fills in a solid band behind a probability bands view. To be used from the OnGraphDraw attribute. Usage:

* Set "Evaluate before drawing" AND "Evaluate after axes, before data"
* Set the [[OnGraphDraw]] expression to:

:<code>roleChanges := [[Plot_solid_prob_band]]( canv, info, roles )</code>
* Select the bands view for your result.
* Make sure you have Color=.Probability for the pivot.

The function uses the lower percentile color (for example, for the 5- to 95-percentile fill, it uses the color for the 5-percentile, with the transparencyMask applied. The transparency mask in an integer between 0 and 255, where 0 (or null) is fully opaque, and 255 is full transparency (invisible). The default is a «transparencyMask» of 128.  Because transparency blends the colors with the white background and with the solid bands behind a given band, the actual colors match the colors of the key exactly only when a «transparencyMask» of 0 is used. However, without transparency, the underlying grid no longer visible.

== Library ==

To use this function ,you must add the '''''OnGraphDraw annotations.ana''''' library to your model.
