// If infinite data is present in the curve data, Qwt is not able to draw a nice curve.
// This class assumes that inf data is removed, and segments to be draw are indicated by start/stop indices into curve
// data.
//
// Single values in the curve are drawn using a CrossX symbol
//
// Here you can see the curve segments visualized. Curve segments are drawn between vector indices.
//
// 0 - 1
// 5 - 7
// 9 -10
