I would like to add a legend dynamically after chart creation.
This legend doesnt have any relation with a series/point, so I dont want to put it into my chart data.
I want to have this legend to implement its click myself.
I know how to handle legend click events.
My question is how to add a new legend to legendsTable?
Thanks in advance.

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 project where the data in the main chart is represented as a bar chart and the data in a drilldown should be line/area/column chart.
Is this possible?
You can manipulate your logic.
Use the click events on the chart and then open a new window with the new charts you want.
Example of chart click event:
https://demo.vaadin.com/charts/#DateAxisAndClickEvent
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
I'm looking for a way of controlling legend items through my custom button.
The button will be placed out of the canvas area.
How can I get a list of legend items, and toggle them through checkboxes?
By doing that, I can give users more spaces to see graphs.
Thanks,

You can look at the legend item names using
chart.series[0].name
chart.series[1].name
To toggle axes on and off, use
chart.series[0].show()
chart.series[0].hide()
e.g. http://jsfiddle.net/BasRN/ shows hiding and showing the first series with buttons, including setting the button text to the series name.
How do I create a simple chart with a single horizontal bar. Xaxis is time and yaxis is one category named execution. I want to show a chart that shows a bar during the times when I have state executing and for states in between I want to display a blank in the same horizontal bar.
What you are looking for, I think, is a Gantt chart. Check out this example: http://jsfiddle.net/highcharts/KNGba/. It is a basic chart with just one element. Now check out this one: http://jsfiddle.net/highcharts/r6emu/. This shows you events during a time line.
