I am using the "Custom Events" highchart plugin by Black Label, to detect right click in my chart. My goal is to use the right click in the chart as "Back" button when drilling out from my custom data. I know highchart has drilling options embedded, but this is a highly custom application, and my problem is that I need a way to detect right click on the x-axis crosshair line.Since the crosshair is following the mouse, 90% percent of the right clicks is triggered on the crosshair line itself, and I can not manage to detect that click. I need the event to be catched inside highcharts, because there is multiple charts on my page, and I need to know which chart was clicked on, and on what point.
I hope you understand my explanation and problem.

When I clicks on pieChart chartValueSelected() method called. But now my need is when I click in center in pieChartView, there will be no action perform.
I don't know what kind of chart (or Library) you used.
In this situation, the contents of function you written seem not to matter.
So I will explain the general situation.
You can place a transparent button in the middle of the pie-chart.
Then link that button to your "chartValueSelected()" function.
I am noticing something strange; I have a click event on a chart, and the chart fire up the event no problem.
Then I add a link in the tooltip, but when I click on it; the chart event fire, not the one that should open the link.
It works only if the tooltip will render on an area that is not part of the plot area (say, a value is high enough to render a tooltip on the title bar; if I click on that link, it will work).
I suspect that there is some sort of parameter that tell highcharts if the link in the tooltip is above the chart plot area? Otherwise it is impossible to have the tooltip open a link, if the highcharts click event is enabled.
You need to set useHTML flag as true.

I have a charts done in highcharts in which I show and hide series depending on a checkbox (if the user clicks on a checkbox and all series are shown, if he unchecks the checkbox, some series are hidden).
It is working great.
Now I have an issue with the legends in the chart: if the series are hidden and the users enables a legend, the segment of all series (hidden or not) are shown in the chart.
I would like to handle the click item so I only handle series that are being shown.
To do that, I created an eventhandler for the legendItemClick event.
Inside it, I am able to access the legend (using this) but I am only able to call functions in a legend level, affecting all series. Is there anyway I could get to a series level?
Thanks!
Edit: created a jsfiddle as an example: http://jsfiddle.net/JLkGm/1/
Steps to reproduce:
1- unmark the checkbox
2- click twice in john + joe
Note that the segment related to Jane + Janet will show up
I would like to prevent this segment from showing if the checkbox is not checked.
ps: sorry for the js code in the checkbox event handler, we are using coffeescript, the original code was this one
toggleCompareData: (toggle) ->
columnName = COLUMN_HIGHCHARTS_TOKEN + #secondaryPrefix
if toggle
for serie in #chart.series
serie.show() if serie.stackKey is columnName
else
for serie in #chart.series
serie.hide() if serie.stackKey is columnName
It looks like bug, reported to our developers here: https://github.com/highslide-software/highcharts.com/issues/3309
By default, the tooltip appears as soon as the cursor enters the chart. I would like to control when it first appears in one of two ways:
Wait for user to hover over (around) a data point on the chart.
This way the user can look at the entire chart without the
distraction of the tooltip.
mousedown - is there a way to disable the default mousedown function
and use it for displaying the tooltip instead? And because the
tooltip and crosshair seem to be joined, perhaps the same mousedown
event could fire the crosshair to appear?
number 2 would be best; any suggestions/solutions would be appreciated!
Number 2 is possible to achieve by:
disable default Highcharts tooltip
create point.click event handler
in above handler, create your own tooltip (it's simple div with some CSS)
make proper position for tooltip (accessed via this.point.plotX and this.point.plotY
Like stated in the title, I got the problem when I click on some slice of pie. I call function, which displays hidden div with the second pie. It appears correctly, but then I cannot click on that first pie and even tooltips are not displaying. And the second pie is all black, but that is the lesser problem, I think... Thanks for advices in advance!
Here's your fiddle with my changes: jsFiddle.
To fix hover and click events on first chart, I've deleted position: relative of second container.
To fix issue with black colors, I moved colors declaration into Highcharts.Chart({...}). Otherwise, you'll re-rewrite Highchart colors while creating the second chart.
