Hello Katie

Thank you for reaching out to us.

You can't see the table because you've created a Simple Table, which is the only table type that can't be used for creating charts.

When working with this table type please note:

• These simple datatables are not saved in the database like manual tables, but instead, their data is stored in the database table wp_wpdatatables_rows. So, pulling data from the database is a bit more complex because this database table stores data in JSON format, not like manual tables (columns * rows).
• There is no front-end editing, sorting, search, filtering, or pagination in this table type.
• Creating charts from this table type is not yet possible.
• You can’t use foreign keys, placeholders, or conditional formatting, but each cell can be formatted separately.
• Setting border types and thickness is not included.
• Add-ons can’t be used with Simple data tables.

Hi again Katie

Basically, any other table type would do. You can take a look at our documentation about charts. Most important thing to note is that charts support only one string-type column (single or multi-line strings, URLs, emails, etc) while all other columns need to be numerical (integer or float).
