Also, the default precision on the axes ticks seems to round to 1 significant digit and tick will read for example 0.10 until its closer to 0.20 and switch over, I would prefer continuous update at higher precision 0.11, 0.12, … etc… as the view is panned. And perhaps a way to manually choose how the tick numbers are formatted.
Ideally the tick location, format, and movement logic for Legend Grid Annotation would work more like vtkChartXY where the tick for 0.1 itself moves rather than staying still and changing value.
