I found {{$Chart.point.name}} in this tutorial, and have found it quite handy for drilldowns… but I’m sure there’s so much more!

Agreed. This would make for better labeling.

This is something we’d like to get documented, but the usual caveat of “until we actually document it, it’s a ‘use at your own risk’ situation” definitely still applies. $Chart.point is a reference to the Highcharts Point Object for the “point” you clicked on. Not everything that comes through is documented by Highcharts though, so especially take care if you are trying to use something that Highcharts doesn’t even document. In any case, here are some of the ones that I think might be useful (links to Highcharts documentation where it exists):

• name


• color


• category


• 
  percentage
  


• 
  series - This is actually a reference to the point’s series, so…
  • 
    name (i.e. $Chart.point.series.name)
  
  
  • type
  
  


• total


• x


• y

Woot Woooot!!!
Thank you!!!

Sure thing! This does allow for some nice touches with “smartly” updating Title/Subtitles on your charts, or setting conditions on separate models. Those are the two big use cases we’ve seen thus far, but as always, we’re excited to see what you all come up with.

Can I use this for actions other than a chart drilldown?

I set a series to open a popup on click (which works great!) but the {{$Chart}} syntax used in the popup (in the title or elsewhere) isn’t returning anything.

Anyone have an answer for this?

Which version are you running? I seem to recall that we rolled that out in Rockaway. Here’s some Page XML that seems to be working for me:

Ha. Well, I haven’t actually tried it again, since there wasn’t a response…
Thanks for the fix!

Good news everyone!
We’ve added information about the $Chart merge variables in our documentation: 

http://help.skuid.com/m/components/l/293051-visualizations-charts-and-graphs#$ChartMergeVariables

As J. stated, we were hesitant about explicitly listing these variables as they are based on an external API. We’re listing them now with the disclaimer that, should Highcharts deprecate these APIs, Skuid cannot support any broken merge variables. I think it’s safe to say that would be an unlikely event, but it’s wise to keep in mind.
