Current Behavior: 

When we use the chart macro on Confluence Cloud, we are not able to display the 'Jira issue count' in the chart on pages.
The chart macro doesn't recognize the Jira count as number, but a node.

Suggested Behavior:

Ability to recognize 'Jira issue count' as a number so that we are able to use this count to display in the Chart macro.

Steps to Replicate:

1. Insert the chart macro on a page.
2. Add a table in the chart macro and use 'Jira issue count' in the column values.
3. Publish the page.
