How can we control the elasticY recalculation of the Y axis range, on a scatter plot, to be bound by the brushes Y range? Thus if a scatter plot has a brush bounded on the Y axis between [6-8) and the elasticY recalculates the new Y axis range to be [3-7] we would like the new Y axis range to be [3-8], because if it used 7 the top part of the brush would be off the screen.
.elasticY(true)
A jsfiddle example.
- Brush the 1st scatter plot x=8, y=[6,9) "Around the two dots". Everything looks good.
- Brush the 2nd scatter plot y=8, z=12 (Around the single dot). The brush on scatter plot #1 is out of bounds.
We would like to restrict the Y axis on scatter plot #1 so the brush is still in bounds. Is there a straight forward way to do this or an override?
Actually our scatterPlots only use a yAxis brush.
