Hello,
I did'nt found a solution for my issue, but i'm quite sure it's possible :)
As you can see in the attachment, i use a line chart to render my data.
There are 2 lines, representing 2 levels for an exercise, and each plot is
a score obtained during a session.
My actual datatable is :
[
[1,1,5],
[2,2,4],
[3,3,3],
[4,4,2],
[5,5,1],
[6,11,13],
[7,null,10],
[8,null,16],
[9,null,1]
]
columns are :
data.addColumn('number', 'X');
data.addColumn('number', 'Niveau 1');
data.addColumn('number', 'Niveau 2");
Actually, I don't know how to add the date information (data are grouped by
plot, actually we have 9), and there are 2 dates for a same plot (one date
for level 1, one date for level 2)
My lines and data are ok, but the goal is to display the date of the score
in the tooltip when we put the mouse over a plot.
I think i have to specify which columns to use and set them, but how ?
how can I perform this ? could you send me a basic datatable sample and/or
options ?
Thanks a lot :)
