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)

\brief A 2-D plotting widget
|
||||
|
||||
QwtPlot is a widget for plotting two-dimensional graphs.
|
||||
An unlimited number of plot items can be displayed on
|
||||
its canvas. Plot items might be curves (QwtPlotCurve), markers
|
||||
(QwtPlotMarker), the grid (QwtPlotGrid), or anything else derived
|
||||
from QwtPlotItem.
|
||||
A plot can have up to four axes, with each plot item attached to an x- and
|
||||
a y axis. The scales at the axes can be explicitly set (QwtScaleDiv), or
|
||||
are calculated from the plot items, using algorithms (QwtScaleEngine) which
|
||||
can be configured separately for each axis.
|
||||
|
||||
The simpleplot example is a good starting point to see how to set up a
|
||||
plot widget.

||||

||||

|
||||
|
||||
\par Example
|
||||
The following example shows (schematically) the most simple
|
||||
way to use QwtPlot. By default, only the left and bottom axes are
|
||||
visible and their scales are computed automatically.
|
||||
\code
|
||||
#include <qwt_plot.h>
|
||||
#include <qwt_plot_curve.h>
|
||||
|
||||
QwtPlot *myPlot = new QwtPlot( "Two Curves", parent );
|
||||
|
||||
// add curves
|
||||
QwtPlotCurve *curve1 = new QwtPlotCurve( "Curve 1" );
|
||||
QwtPlotCurve *curve2 = new QwtPlotCurve( "Curve 2" );
|
||||
|
||||
// connect or copy the data to the curves
|
||||
curve1->setData( ... );
|
||||
curve2->setData( ... );
|
||||
|
||||
curve1->attach( myPlot );
|
||||
curve2->attach( myPlot );
|
||||
|
||||
// finally, refresh the plot
|
||||
myPlot->replot();
|
||||
\endcode
|
||||
\endpar
