View Menu
The "View" menu contains operations for changing the user's view
to the data:
Opening multiple views
to a graph,
setting the scale
of a visualization or
getting information.
Note:
menu operations can also be invoked without the mouse by using
keyboard commands.
Multi-View Management
-
Open New View
This operation opens an additional view (base window) to the graph.
Read more about
multi-view and multi-graph
in the concepts document.
All views of a graph are coupled with each other, so interactions
in one view affect the graph visualization in all the other views
of the same graph, too.
But loading a graph in one view disconnects this particular base
window from the other views, so the new graph is only displayed
in the view where the load operation was invoked.
This way, the user can load many different graphs at a time
(multi-graph). The maximal number of open base windows in
uDraw(Graph) is 64.
-
Open Survey View
This operation also opens an additional view to the graph, but with
some special properties.
Read more about
multi-view
in the concept document.
The base window, where this operation was invoked, is called
detail view.
A survey view, which appears after using this operation, shows
the graph in a reduced scale to see the whole structure at any time.
The scale of a survey view reduced automatically when the window
size is manipulated.
A survey view shows the currently visible area of the corresponding
detail view with a blue rectangle.
This rectangle is only visible in a survey view when the scale is
small enough to show the complete graph.
So, if the blue rectangle has become invisible in a survey view,
then use menu "View/Fit Scale to Window" (see below) to get the
blue rectangle back.
If the scale of the survey view is 100%, because the graph is small
enough and already completely visible in the detail view, you
will not see the rectangle as well.
You can move the blue rectangle by holding the left mouse button
in order to scroll in the corresponding detail view.
Another useful feature of the survey view is automatic scrolling.
When the user selects a node in the survey view, the same node is
brought to the center in the corresponding detail view with
animation.
Scrolling to the selected node can be switched off in dialog
Options/General Settings...
by deselecting checkbox "On selection in Survey View".
Animation can be switched off in dialog
Options/General Settings...
by selecting checkbox "No Animation".
The maximal number of open base windows in uDraw(Graph) is 64.
Scaling
-
Full Scale
Used to set the graph visualization scale to 100%.
-
Fit Scale to Window
Used to set the graph visualization scale to the maximal
rate where the graph is completely visible in the base window.
-
Scale...
Used to set the graph visualization scale to any rate between
1% and 100%. Read more about
scaling
in the concept document.
After selecting this menu entry, a
scale dialog
window will appear to set the scale.
In a reduced scale, all interactive operations are still available.
The scale of a graph can only be reduced with this operation, but
not magnified.
To magnify a graph visualization, choose a bigger font with dialog
Options/Layout Settings....
