7.5.1 SIEsGraphCustomWidget
General
Using SlEsGraphCustomWidget, you can display geometrical objects (point, line, square,
square with rounded corners, ellipse, arc, text) and curves from interpolation points (e.g.
measured values, characteristic).
The objects are organized in one or several contours. These can then be displayed, either
individually or combined; they can also be entered, selected and deleted.
Using functions, the objects are added to the currently selected contour, and these are then
drawn in this particular sequence. If you wish to draw the object in a specific color, then you
must set the appropriate pen color before adding. All objects subsequently added will be drawn
in this pen color. In addition to the pen color, you can also influence the pen width and pen
style. For closed objects such as square, square with rounded edges and ellipse, before adding
the objects you can set a fill color.
Every contour can be brought into various modes:
● Standard display of all object types.
● Points can be connected to create a polyline, and can therefore be displayed as curve/graph.
● The area between points, lines or arcs up to the X axis can be filled in with the currently
selected fill color. For instance, you can use this option to visualize residual material when
turning.
If, in this mode, points are displayed in addition as polyline, then the complete area below
the curve up to the X axis is filled. The points, lines and arcs can be located in all four
quadrants.
You can move along one or several contours using a special cursor mode. To do this, the
cursor is set to the first or last point object of a contour or, starting from the actual cursor position
is moved either forward or backward within the contour of a point object.
When required, a second Y axis (right) can be displayed with its own scaling. This is coupled
to the first Y axis (left) through an offset and a factor.
Based on a specified X coordinate, using a search function, a point previously added to the
contour can be found, and if required, the cursor can be set to this point.
You can also configure contours as ring buffer with an adjustable size.
As a result of the serialization, the actual state of the SlEsGraphCustomWidget can be saved
in a file in binary form - and also restored.
The SlEsGraphCustomWidget can be operated using the "Pan" gesture (where the view is
shifted) and the "Pinch"/"Spread" gestures (zooming in and out of the view).
Using the mouse, you can shift the view (left mouse button + Move), and you can zoom in and
out (mouse wheel).
For performance reasons, the display is not automatically refreshed. Depending on the
particular application, you can initiate the refresh by calling the appropriate function.
