I’ve been poking around the Highcharts API reference and I can’t find a clear list of all of the ways in which you can format text, such as for a data point in a series. I have been able to remove the decimal places in my data labels on a column chart, but there are other things that I’d like to do and I can’t find a complete list of the possibilities. I also looked under sprintf on a C reference site (based on what it said in the Highcharts documentation) but that was pretty confusing for me.
Dear Jamie,
I’m afraid your question is rather something for Highcharts experts/community 
did you try their forum, too?
https://forum.highcharts.com/
You can find some information about how we handle the Highcharts API in our docs here: https://docs.skuid.com/latest/v1/en/skuid/components/original/visualizations/chart/#working-with-highcharts-merge-variables
There you will also find the link to the Highcharts API/documentation, that you probably already know: https://api.highcharts.com/highcharts/
Here are a few community posts we’ve used in the past for help with writing code for using the Highcharts API:

https://community.skuid.com/t/how-can-i-edit-the-tooltips-that-appear-on-chart-visualizations
I hope this is helpful for you.
