Hi, Adrian.

Firstly, I would like to sincerely apologize for the delayed response as we have been experiencing an unusually high number of tickets. I am sorry that it has taken longer than usual to respond to your concern and your patience is highly appreciated.

Every chart engine has its own layout and its settings.

We use free libraries for chart engines, and they are limited as to what we can change from within the plugin's UI.

You can check out all the available chart engines and examples of wpDataCharts documentation here . 

If the options you need are not in the chart creation wizard,  you can try to find a custom solution using chart callbacks.

You can check our documentation about wpDataCharts callbacks. 

On that page you will find one example of Apex Chart,  we have changed colors and  for ApexChart pie chart, but you will have to modify that example for your goal.

• 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.
