setExtremes method issue for heatmap plot with boost module

[AndreiKoriagin]

There's problem with boost module when using setExtremes method.

Expected behaviour

rectangles with lower cathegory value are hidden.

Actual behaviour

rectangles with lower cathegory value are visible outside of plot area.

Live demo with steps to reproduce

Affected browser(s)

Chrome (Windows)

I reached expected behavior by changing line 2028 in boost.src.js (method createAndAttachRenderer):

target.boostClipRect.attr({
    x: chart.plotLeft,
    y: chart.plotTop,
    width: chart.plotWidth,
    height: chart.plotHeight //height: chart.chartHeight <- instead of this
});

Thank you for the reporting.

It looks like the same issue as the: #6865

I'm having this problem as well. Is there a current work around?

@cvasseng As far as I can see there's a potential room for optimizing in the createAndAttachRenderer function. This function runs 1200 times in the line-series-heavy-stock sample, one for each series. On each iteration, it runs function like boostClipRect.attr, boostResizeTarget and boostClear. When it renders to a chart-level canvas, this is repeated 600 times with the same parameters, which seems redundant.

@TorsteinHonsi yes, there's some room for improvement there. It needs to be called for every series if not boosting on chart level, but the cliprect should only be set when the chart has reflowed, and when it's first initialized.
