Chart attachment in Views Causes Error on parent chart: Data column(s) for axis #1 cannot be of type string

Can you send the database log that shows which line is problematic?

@lduncan - can you ensure that the chart format on your attachment is set for "This chart_extension (override)"? I'm not able to recreate your issue otherwise.

@andileco, yes the chart format is set to "This chart_extension (override). Whenever I set the Axis settings to "Use primary Y-axis" the parent chart gives the error "All series on a given axis must be of the same data type." Even though both parent and attachment are filtered show data from the same content type.

If I set the Axis setting to "Create a secondary axis" that's when I get the error "Data column(s) for axis #1 cannot be of type string." In both settings the chart attachment display is fine.

@lduncan I'm unable to recreate this. Would you be able to record a screenshare or provide more details? What charting library are you using? What version of PHP are you on?

I am seeing this as well. I cannot create more than one chart page in a single view. On Drupal 10.3.2. I can always create the initial display as a chart fine and it works great. Every single time I create a 2nd display in the view that is a chart, it works, but when I toggle back to the first display, it gives me the error below. I go up to the Chart settings on that initial display, and see that nothing is chosen for the Label (but it was before I created the 2nd display). I choose the correct value again and save that and the preview for the initial display now works again but then I have an issue with the second display. When I do get an error it shows with a red background in the Content area in the preview: Data column(s) for axis #0 cannot be of type string×

I am facing the same issue. I am using Drupal 10.3.2 with chart-type columns, and the Label field is set to "No label field."

@alokdrupl, that might just be a separate issue purely related to the "No label field"; if so, can you create a new ticket?

@dbdrupal, can you ensure that your Chart format links are italicized, like in the attached image? If they are not, it means your settings on the one display are overriding the settings on the other. To change this, click the "Chart" link and then select "This display only".

That did it @andileco, thanks! Works fine now with multiple displays.
