Cubism - value for selected time and row

Question

I love Cubism.js

But i want to implement a feature i am missing from the demo.

And that is the need to see the value for a selected time and row. When i have a mouse-over on the graph - i would like to show the value for the row the mouse cursor is on (see picture beside the vertical line)

How could this be done?

Do i have a chance with CSS or do i need to dig into d3.js ?

edit: i have found the Stock-Demo ... but still now clue how this is done :(

Answer 1

I could achieve that easily by playing with the CSS. First, hide all values:

.horizon .value {display: none;}

Then show values on hover:

.horizon:hover .value {display: inherit;}
