// 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
//
// / ^

// Curve / / \ ----- X
//
// Values 1.0|2.0|inf|inf|inf|1.0|2.0|1.0|inf|1.0|1.0|inf|1.0|inf
// Vec index 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10| 11| 12| 13
