I've been using the SciChart WPF SDK for a little while and I was just trying to change a tooltip customization. There was great documentation on the website which helped point me in the right direction, but it also pointed me to the samples, specifically the topic on Using CursorModifier Tooltips. Not only was it helpful to be able to run the sample app and change various setting to see the result without recompiling, but it was very slick that the samples provided the mechanism to export its source code for further experimentation. Very smooth and saved me quite a bit of time this afternoon!
