Hi, Tobias

Thanks for reaching out to us.

- Any colour setting that you can't find on our charts wizard,

is something that would require a custom callback.

Our charts are based on free chart engines, and our built-in plugin functionality is limited by it.

That is the default behaviour of the charts engine, but when you need some custom solution you can check our documentation about wpDataCharts callbacks. 

• Every chart exposes several options that customize its look and feel. Charts usually support custom options appropriate to that visualization. wpDataChart callbacks allow adding options that are available in Google Charts API, Highcharts API, and Chart.js API. 

• All necessary resources are available in charts engines API (depends on which one you use). Every engine has a different approach to chart settings. In wpDataChart callbacks, you have to adopt those settings to the wpDataChart object (you can take a look at examples for each engine in our documentation, and also in the Support help center). A huge number of examples for any area of programming can be found on stackoverflow.com (typing your problem in google and at the end add "site: stackoverflow.com" and Google will search only that website). Also, a lot of examples of charts, chart settings, and customization can be found on jsffidle.net (typing in google for example "line chart highcharts jsffidle")
• Please note that using hooks or wpDataTable and wpDataChart callbacks requires a certain level of programming skills and included support refers only to advice.

Hi, Tobias

Our ticketing system automatically temporarily closes tickets after 7 days, but if someone sends a response, it gets re-opened immediately.

My last response was 6 days old, so it might be an error if you saw the ticket marked as closed. I can assure you I didn't close it, in any case.

Thank you, and if anything else happens that we might assist with, please don't hesitate to open a new ticket.
