only 1 strings/date column?

i explain it better what i want to do:

i am trying to do a simple chart that has:
on axis X a DATE (july 2022.,october 2022..etc)
on axis Y an amount (1500,2200..ecc)
then i want to have in the graph a point where the the x and y value meet, that when i hover show me a text (the items that hase generated that amount in that date)
so july 2022 – 1500 –>text1
october 2022 – 2200 __< text2

I can’t get to do it

i am not able to insert the text1, text2…
these are example data:

PERIODO,VALORE,EVENT
date,number,string
1/7/2022 1500 text1
1/10/2022 2200 text2

how can i do?
thanks

Hi @stefanocps,

Thank you for using Visualizer.

To create dots on the line chart, you can use the manual configuration field in the chart settings and add the following code there.

{ "series": { "0": {
 "pointShape": "circle",
      "pointSize": 5
}
} 
}

The tooltip can’t have custom text specified in the source file because only the series are specified there and all of them should be of the same type. Therefore, a string column for the tooltip can’t be near a series of type number.

Best regards,
