Hello amr

Thank you for your purchase.

I cannot see your attachment, so I don't know what the actual issue is.

wpDataCharts can accept only one string-type column. All other columns need to be numerical (integer or float).

Hi again amr

You can create a secondary Y axis with Highcharts.

An example can be seen in our FAQ section.

You're welcome amr

Unfortunately, that's not something we can change. You can only use one string-type column when creating a chart. You either need to restructure the table, or convert your string-type columns into integer or float. There's no other workaround.
