I have a Vaadin chart like this:
.
My goal is to get the hovered X value when clicking on the chart. Based on the previous image, I would like to get what month area is being clicked (the selected area is blue coloured in the image).
I've added a PointClickListener to that chart and inside that event I can get the needed information, but I have to click exactly hover the point. Clicking in the month area is not fired the PointClickListener:
chart.addPointClickListener(
pointClickEvent -> {
//Here I get the selected month:
int monthIndex = event.getPointIndex();
So I would like to know if there's any method to obtain the hovered month by only clicking in that area, not exactly above the point.
You could use Chart click event, and you will get the coordinates of the click, the event has info of the coordinates, for your purpose you could use the xAxisValue to know which point is in the clicked zone.

I have some annotations in my chart and I would like to get the specific day of my xAxis datetime when I click on one of those.
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.

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
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.
