Google chart line, combine multiple tooltips into one

Question

Can someone explain me how to combine multiple tooltips into one, similar to what Google is doing in Google Search Console. I did not found any example in https://developers.google.com/chart/interactive/docs/gallery/linechart achieving this result (check below image):

I guess Google is using the Google Chart libraries.

Additionally, you can see in the example above, the vertical line when you hover over a specific date. How that is done as well?

try setting this chart option --> aggregationTarget: 'category' — WhiteHat
it does not work, but i found out that what i was looking for is: focusTarget: 'category' — tempotempo

To solve this issue you need to add the following parameter in the options:

focusTarget: 'category'

'category' - Focus on a grouping of all data points along the major axis. Correlates to a row in the data table.
