Custom PlotChart layout

Question

I'm stuck trying to determine where/how to interrupt the
rendering of a PlotChart's PlotSeries in order to modify the
placement of its elements. We've customized a PlotChart to display
labels for each data point. So each PlotSeries has a custom item
renderer. The problem is that the labels overlap if their values
are too close to each other. I want to modify the placement of such
labels so that they don't overlap, but I need to know the initial
placement of all of the labels at the same time in order to move
them appropriately. Thus I can't simply override the custom
renderer's updateDisplayList() method, as it only lays out each
PlotItem individually, without knowledge of the others in the
series. I'm trying to figure out where in the rendering process I
can put my layout code where all PlotItems will have been intially
laid out already and I will have access to the entire data set at
once. It doesn't seem like I can do this in the PlotChart's
updateDisplayList() method, as the application LayoutManager is
calling each custom renderer directly, not through the chart's
updateDisplayList() method, as I would have thought. No clue what
to do.

Hi,
This depends on the IView properties, so open IView properties in property editor and play around with
Height properties like Height Type, MaxAutoHeight, MinAutoHeight.
