Number input with min and max values

[Anonymous]

I'm doing some custom R HTML visuals in Power BI. I can get a number input in Power BI by adding

"TestNumeric": {
  "displayName": "Number",
  "description": "test number",
  "type": {
    "numeric": true
  }
}

in capabilities.json (and adapting src/settings.ts accordingly).

I would like to constrain this number input with a minimum and a maximum value. How can I do that?

One has to modify src/visual.ts.

At the beginning, in the blocks of imports, add:

import VisualObjectInstanceEnumeration = powerbi.VisualObjectInstanceEnumeration;

Now, at the end, replace the function enumerateObjectInstances with this one:

    public enumerateObjectInstances(options: EnumerateVisualObjectInstancesOptions): VisualObjectInstanceEnumeration {

        //var settings: VisualSettings = this.settings || VisualSettings.getDefault();
        var enumeratedObjects: VisualObjectInstanceEnumerationObject =
            <VisualObjectInstanceEnumerationObject>VisualSettings.enumerateObjectInstances(
                this.settings || VisualSettings.getDefault(), options
            );

        if (options.objectName === "YOUR-OBJECT-NAME") {
            enumeratedObjects.instances[0].validValues = {
                YOUR-PROPERTY-NAME: { numberRange: { min: 8, max: 20 } }
            };
        }

        return enumeratedObjects;
    }
