Hello Logbit

Thank you for your purchase.

Unfortunately, Highcharts engine is the only engine that offers export, but CSV and Excel formats are not included. The only included file types are PNG, JPEG, PDF and SVG.

To enable them, you simply need to enable exporting in the last step during chart creation:

Hi again Logbit

The free libraries chart engines provide comes without this, so it's not included in the built-in options of the plugin.

That is default behavior of charts engine, but if you need some custom solution you can check in our documentation about wpDataCharts callbacks. I suppose that's what you need.

• 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 Support help center). 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 certain level of programming skills and included support refers only to advice.
