    You should use something like this:

    options.dataViews[0].categorical.categories[categoryIndex].source.displayName;

// categoryIndex is an index of the category that you want to include to the tooltip

      Sorry, didn't get you.
      what should be the assignment for displayName ?

       private static getTooltipData(value: any): VisualTooltipDataItem[] {
            return [{
                displayName:,
                value: value.value.toString(),
                color: value.data.color,
                header:value.data.category
            }];
        }

      Thank You.
