Hi @leidig54 ,

Greetings from Syncfusion. We have analyzed your scenario from the provided exception texts and we found that you are trying to use number format in the category axis. As the category axis does not support number formats, the NoSuchMethodError exception is thrown as there is no getter provided in the category axis class for the number format. The number format can be used only in the numeric axis. For further reference on the axis types and their properties, please refer the user guide below,
https://help.syncfusion.com/flutter/cartesian-charts/axis-types
If you have further concerns, please revert us.

Regards,
Sriram Kiran.
