The link you have provided refers to our wpf chart. This is a newer control and the win forms chart does not have an equivalent to it for all features.
If I understood you correctly you want to set a different source to each series and this is not possible with the win forms chart. You can either use the approach I previously presented, or you can manually set the items for each series. That means that you'll have to give up any automatic bindings and will need to manually populate the Items
of each series.
