- 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)

Synthetic point data\&.
|
|
|
|
\fBQwtSyntheticPointData\fP provides a fixed number of points for an interval\&. The points are calculated in equidistant steps in x-direction\&.
|
|
.PP
|
|
If the interval is invalid, the points are calculated for the 'rectangle of interest', what normally is the displayed area on the plot canvas\&. In this mode you get different levels of detail, when zooming in/out\&.

Calculate the bounding rectangle\&. This implementation iterates over all points, what could often be implemented much faster using the characteristics of the series\&. When there are many points it is recommended to overload and reimplement this method using the characteristics of the series ( if possible )\&.
