I would like to use a custom attribute to allow me to “link” points between various charts. What is the correct way to add a custom, unique attribute value (e.g. key=‘item1@item2@item3’) to each point?
It’d be nice if I could do something like:
data=[{
x:[1,2,3],
y:[2,4,3],
customattributes: {
attributename: [‘v1’,‘v2’,‘v3’],
anotherattributename: anotherarrayofvalues
}
}];
But ‘customdata’ assigns the values to the __data__property of the DOM element. I would like to create a custom attribute for each g.point element so that I can use JQuery to create a collection of points.
Actually, I think I can use the ‘ids’ array to accomplish what I need, but a custom attribute would be easier in that I would not have to ensure uniqueness…
