Queryrecord function returns a datasubset. This means you can use the .totalCount attribute of the variable to conditionally display your chart.

You did not pass in the keyword argument, 'logicalExpression|filter|search': , before you declared your type!QueryFilter. Also keep in mind that because you are adding .data to the end of your queryrecord() expression you will only be saving the data portion of the query. This means your next local variable for total will not evaluate correctly, as .totalCount will only available if you save the full datasubset in your local variable.
