In the tooltip template documentation the only input seems to be the value object which has an x and y value. However, our original data additional metadata that we'd like to show in the tooltip.
To be more specific, each data point has a date for the x value, a dollar amount for the y value and then there is an additional field that shows the username responsible for that datapoint. I'd like to be able to include that username in the tooltip for the point in the chart. Is that possible?
data = [{forecastDate:
new
Date(2018, 8, 15), forecastAmount: 3500.35, userName:
'John Doe'
}, ..... more of those .... ];
if i'm using forecastDate for the X-Axis and forecastAmount for the Y-Axis, is it possible to use the userName field in the tooltip for each point?
