7.21.1 Customizing the patterns

All patterns can be customized by

... altering the colors of the band
... altering the density of the patterns using the method PlotBand::SetDensity() The density is specified as an integer in range 1 to 100 where a higher number means a higher density (smaller distance between the lines). For example setting the density of the 3D plane above to 60 gives the result

Figure 111: Increasing the desnity in a pattern [src]
... enabling or disabling a frame around the pattern by using the method PlotBand::ShowFrame() The band will be given the same color as the band.
... finally you can change whether the band should be drawn on top of the plots or beneath, (by default the bands are under the plots), using the PlotBand::SetOrder() as the following example show

Note: 3D planes actually carry another possible modification. You can specify the vanish point to change the perspective used. You can't access the method to change the horizon directly but you can access it through


  $band
->prect->SetHorizon(
$aHorizon)

assuming that the band is a 3D plane.

To finish this section we give one final, more creative, example on how to use the bands.
