== Plot_solid_band(canv, info, roles, x, lowerY, upperY, color) ==

Plots a solid band between a «lower» and «upper» curve in the given «color» behind the data from an [[OnGraphDraw]] attribute expression. To use, enable both "Evaluate before drawing" and "Evaluate after axes, before data".  In your call, you should do an IF on the view mode of interest, for example:
<code>
:[[If]] info[ [[OnGraphDrawItem]]='ViewMode']='Sample' [[Then]]
::roleChanges := [[Plot_solid_band]]( canv, info, roles, x, lowerY, upperY, x, 'LightGreen' )
</code>

== Library ==

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