QwtPlotHistogram represents a series of samples, where an interval is associated with a value (
).
The representation depends on the style() and an optional symbol() that is displayed for each interval.
- Note
- The term "histogram" is used in a different way in the areas of digital image processing and statistics. Wikipedia introduces the terms "image histogram" and "color histogram" to avoid confusions. While "image histograms" can be displayed by a QwtPlotCurve there is no applicable plot item for a "color histogram" yet.
