Accessing column header.

[Anonymous]

How can I get the header of a column I have used for creating a visual.I need to display the column name in the Tooltip.

Are you developing a custom visual?

If so, you can get column name using displayName propertry of the metadata.

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.

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
