I am using TeeChart2015X64.ocx, I see a new hover functionality in General Tab, The issue is when the number of Points on X-Axis are high then Mouseover in chart x-axis highlights wrong x-axis labels.
Can Anyone let me know how to disable this functionality from code since I don't see any function for the same.
Thanks
Akshay
Yes, try this:
TChart1.Hover.Visible = False
Edit 1:
For VC++, download the Hover headers from here and extract with the other TeeChart headers.
Edit 2:
To disable the Hover only for the bottom axis you can do this:
TChart1.Axis.Bottom.Labels.Selected.Hover.Visible = False

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 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
Does anyone know the setting in highcharts (I've looked through the API but I can't seem to find it - maybe looking in the wrong place?) where I can disable the chart's ability to resize when I click on a legend item?
http://api.highcharts.com/highcharts#legend
If there are two lines on the graph, and toggle off one of them on the legend, the graph resizes to show the one line full sized. I want to prevent this functionality.
There actually is a simple solution to this provided for by the API:
chart: {
ignoreHiddenSeries: false
}
I'm pretty sure this is the behavior you desire.
I'm developing a chart that have 2 splines and 2 scatter. I use the default tooltip formatter to exhib a tooltip based in the spline data. But when I hover a scatter despite I hide the default tooltip, before show the scatter one, it appears to have triggered again.
How can I prevent the default tooltip to be triggered?
ps: im using Highcharts 3.0.1
EDITED: I tried "chartObj.tooltip.enabled = false" but it didn't work.
If you don't want to show the tooltip for a particular serie in the chart, see if setting
enableMouseTracking: false
on you desired serie's properties does it.
Hope this help.
I solved using this code:
chartObj.tooltip.options.enabled = false;
Setting to "false" when I hover and to "true" on mouseout.
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.
