Hello Eddie

Thank you for your purchase.

You cannot use multiple string-type columns in wpDataCharts. Chart engines allow only one string type column.

Can you show me your table and the chart in Excel (for example), and I'll see if there's a workaround for what you're trying to achieve?

Hello again Eddie

You would need to create a table in this way:

1st column should remain the date.

2nd column should be "Restylane"; 3rd column "Merz Aesthetics" and so on.

For each date's row, you need to add "1" below a page name where it exists on these dates. So, you'll need to restructure the table in order to group the column values. 

Hi again Eddie

That's being pulled from the chart's engine, but it can be changed with 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 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.
