This is the Qt OPC UA representation for the OPC UA AxisInformation type defined in OPC-UA part 8, 5.6.6. It contains information about an axis which can be used for multiple purposes. A common use case could involve the plotting of display data. The engineering units and the title are used for the text on the plot, range, axisScaleType and axisSteps provide the scaling and the axis ranges of the plot.
Constructs axis information with engineering units engineeringUnits , range eURange , title title , scaling axisScaleType and axis steps axisSteps .
Constructs axis information from rhs .
设置值从 rhs in this axis information.
Returns the scaling of this axis, defined by QOpcUa::AxisScale .
另请参阅 setAxisScaleType ().
Returns specific values for each axis step.
This value is empty if the points are equally distributed and the step size can be calculated from the number of steps and the range. If the steps are different for each point but constant over a longer time, there is an entry for each data point.
另请参阅 setAxisSteps ().
Returns a reference to the axis steps.
Returns the lower and upper values of this axis.
另请参阅 setEURange ().
Returns the engineering units of this axis.
另请参阅 setEngineeringUnits ().
Sets the axis scale type to axisScaleType .
另请参阅 axisScaleType ().
Sets the axis steps to axisSteps .
另请参阅 axisSteps ().
Sets the lower and upper values of this axis to eURange .
另请参阅 eURange ().
Sets the engineering units to engineeringUnits .
另请参阅 engineeringUnits ().
Sets the title to title .
另请参阅 title ().
Returns the title of this axis.
另请参阅 setTitle ().
Converts this axis information to QVariant .
返回
true
if this axis information has the same value as
rhs
.
