Crosshairs overlapping

[PaulDalek]

Hi,

Behaviour:

It seems that in line chart, in Highstock the number of yAxis affects the number of times crosshair is drawn, while in Highcharts it doesn’t matter how many yAxis there are, the crosshair is drawn only once. Beside of this, 'multiplied crosshairs' in first case overlaps each other, giving the impression that crosshair’s color is darker, please take a look at this example: http://jsfiddle.net/d_paul/bfL2nzk9/2/. Although it occurs only when crosshair’s width is set to 1. Changing this to higher value makes ‘crosshairs’ don’t overlap and crosshair’s color is displayed correctly.

Best regards.

Thank you for reporting. You are right, issue is visible only in Highstock, where extra logic is added to support multiple panes.

Internal note:
uniqueAxis here most probably should compare not only object, but also position of the axis. If axis.pos and axis.len are the same, then leave axis out of the scope. Not sure if this will not break something with plotLines/plotBands/gridLines.

@PaulDalek @pawelfus Tried to locate this issue, but was not able to do so. Does this issue still exist?

Yes, it does, compare:
