The function %HI_GraphCorrectionStart starts the
correction of the flows in graph. This correction allows a user to correct a
data curve in a graph using the mouse.
The function %HI_GraphCorrectionStop stops the correction of flows.
Declaration
%HI_GraphCorrectionStart(
INT in refId,
INT in lineNr
)
%HI_GraphCorrectionStop(
INT in refId
)
When starting the function, the user creates the
correction control points (at the most 50) that helps to define a data
correction by change of their position. These control points are represented
by marks and linked by a correction curve. When you left-click over the
control point and drag and drop it on the new position, it causes the
change. When dragging, the control point, correction curve and data flow
are redrawn.
The function %HI_GraphCorrectionStop stops the
correction. When calling this function, the event OnGraphCorrectionStop
is generated. The changes concerning the correction are saved into data of
graph. They are processed by a picture script. Data can be called by the
function %HI_GraphGetLineData.
