Hi, thank you for trying to help me. In condition, I put there { "max": 1 } in my category but when drag another field, accepts another and blocks my visual.

When you are creating your custom visual, add a max condition in your Capabilities (per https://github.com/Microsoft/PowerBI-visuals/blob/master/Capabilities/DataViewMappings.md).
