dual yaxis tooltip out of position

[nmyvision]

I have a chart with multiple Y axis. when i move one axis down to simulate 2 charts the tooltip does not take into account the top position that is set.

Where in docs you have founs options for height and top?

Edit: Just found: https://github.com/highslide-software/h ... issues/424

Your right it's not documented but its used in there demo

http://www.highcharts.com/stock/demo/ca ... and-volume

The demo is highstock, but it's not in highstock documentation either.

EDIT: I see your edit, I guess i'll see if i can figure out the solution.

So, it's rather Highstock feature, not Highcharts? And it's not working the best without shared tooltip? As reported error on github.

I fixed it, in the tooltip().Render() function line 7570 in the source.

I changed plotTop which I couldn't figure out where it was set probably is not based on the current axis.

here is the change... I'll make a comment in github

placedTooltipPoint = placeBox(
label.width,
label.height,
plotLeft,
//plotTop, comment this out and replace with below...
point.series.yAxis.top,
plotWidth,
plotHeight,
{x: x, y: y},
pick(options.distance, 12),
inverted
);

in the function refresh ( line 7515 to 7522)
for shared tooltip, the plotY are averaged.
when multiple yAxis of different heights are used (typically for volume chart height 1/4 of price chart)
the averaged value forces the tooltip to the top of chart.

Supposing that the first y axis is considered as the main axis, a possible FIX is to add
plotY = point[0].plotY; at line 7521

it may be more elegant to do it via a series config option for tooltip ????
