Qt5 built in qwt (#570)
- qt4->qt5 - in built qt5 6.1.5 because rhel7 is not upto date with qt5, removed findqwt.cmake - made a fix in qwt lib (qwt_plot_layout.h) to work with 5.15 and lower versions for qrect constr. - qt5 forms fixed, qt4 many hard coding forms switched to forms including qtabwidget, scrolls etc, fonts moved to forms - docking option enabled by default, removed option to disable docking feature from "Mode" - added qVersionResolve utility functions to handle compatibility before and after qt5.12 - qtplots (ian's code) takes in gain mode enable to set some settings within the class, with proper gain plot ticks - ensure gain plots have no zooming of z axis in 2d and y axis in 1d - removed placeholder text in qpalette in main window form as its not supportd until 5.12 (so using qt5.9 designer insted of qt5.15 to cope) - tab order Servers: - fixed some error messages that were empty for fail in funcs (mostly minor as if this error, major issues)

.PP
|
||||
\fBQwtPlotHistogram\fP represents a series of samples, where an interval is associated with a value ( $y = f([x1,x2])$ )\&.
|
||||
|
||||
The representation depends on the \fBstyle()\fP and an optional \fBsymbol()\fP that is displayed for each interval\&.
|
||||
.PP
|
||||
\fBNote\fP
|
||||
.RS 4
|
||||
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 \fBQwtPlotCurve\fP there is no applicable plot item for a 'color histogram' yet\&.
