Thanks a lot this is what I need !!
Is there a mirror method of view.getTableRowIndex which return the position
in the graph from the tablerow index ?
This could be done in this way but I am wondering if there is a more
beutiful way:
var rows = view.getViewRows();
for(var i =0 ;i< rows.length;i++)
{
if(tablerow_index == rows[i])
{
chart_position = i;
break;
}
}
Thanka again
