I'd like to change the way data is displayed in the automatic tooltips for line graphs.
It seems that Microsoft have applied a rule concerning the display of data in the automatic tooltips of curve graphs, but we don't have control over it.
I've created a curve chart (x: date y:price) where I have as many curves as countries. If I select a certain year, and hover over one of the curves, I'll get a little label with the country's price. But if I select the whole period and hover over one of the curves again, I'll get a big label with the price of all the countries...
Can you explain the rule applied here? Is it possible to add options to change the way the tooltip is displayed?
