When you use Zedgraph for linegraphs and set IsSmooth to true, the lines are nicely curved instead of having hard corners/angles.
While this looks much better for most graphs -in my humble opinion- there is a small catch. The smoothing algorithm makes the line take a little 'dive' or 'bump' before going upwards or downwards.
In most cases, if the datapoint are themselves smooth, this isn't a problem, but if your datapoints go from say 0 to 15, the 'dive' makes the line go under the x-axis, which makes it seems as though there are some datapoints below zero (which is not the case).
How can I fix this (prefably easily ;)
