Date format in Tool tips

I am trying to control the date format within tooltips - I would just like toget month (words) and year if possible
Here is the chart…

I can get to the Customize>ToolTip section but I am not sure whether it will take date formatting or if it just puts in whatever is in the table?

Hi Tim,

Can you paste a link to your chart again?

Here are instructions for adding a date to the tooltip. This works if the x axis is a date/time axis.

Does that help? If not, let me know.
