Show Charts Third Column Value in ToolTip

Is it possible to have a tooltip on a chart show a value from a third column in the dataset? In my case I have the Name on the X axis the value on the Y axis and I would like to show the date of the data point when hovered.

Thanks for the help.

Is this a bar chart you’re talking about?

No it is a line graph with none of the lines drawn between the data points.

attached is a picture.

Hrm… the problem is that the line chart interprets a ‘3rd column’ as another series of data. A solution for this request (somehow attaching a string with a datapoint) would also fulfull the long-standing chart annotation feature request, but we haven’t figured out a great way to do this as of yet…
