    Can I change the behaviour of the spline curve at all and how it figures out the curve?

    For example in the attached picture my yaxis values of the purple line are 14, 0, 0, 0, 14, 0

    Can i alter the curve to not drop below the 0 line? Is the spline type the right thing for what I am doing here?

    The behavior you describe is expected, because the spline curve is actually an approximation. Basically, the curve runs through the provided control points - the actual DataPoints. When the path between any two of these points is calculated, it takes into account their adjacent "outer" points. If this does not meet your requirements you can use the line type instead. Have a look at the following online resources for an overview of the Line Charts:

    I hope this helps.
