Flot Chart with 3 values in tooltip

Question

I would like to create a Flot Chart with tooltip and 3 values inside. So i created data as follow:

var d1 = [[1678780801000,137.00,'test'],....

I hoped i could place the tootip with

....y=item.datapoint[1].toFixed(2),z=item.datapoint[2];

But i only get undefined. Is there a chance to siple fill tooltip only with desired 3rd value ? Thanks for help.

Answer 1

Flot seems to use only numbers in data so i decided to use data1 and data2.
