The View menu contains operations for changing the user's view to the data: Opening additional views to a graph, setting the scale of a graph visualization, or getting information.
Note: Menus can also be used mouseless with
keyboard commands.
Multi-View Management
This operation opens an additional view (base window) to the graph. Read
more about multi-view and
multi-graph in the concept document. All views of a graph are coupled
with eachother, so interactions in one view affect the graph visualization
in all the other views of the same graph, too. Loading a graph in one view
disconnects this base window from the other views, so the new graph is
only displayed in the view where the load operation was triggered. This
way, the user can load many different graphs at a time (multi-graph).
The maximal number of open base windows in daVinci is 64.
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 is executed, is called detail view.
A survey view, which will appear after using this operation,
visualizes the graph in a reduced scale to see the whole structure
at all times. The scale is 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 rectangle back. If
the scale of the survey view is 100%, because the graph is already completely
visible in the detail view, you will not see the blue rectangle as well.
Another useful feature of the survey view is automatic
scrolling. When the user selects a node in the survey view, the
same node is focused in the corresponding detail view by using animation.
This behaviour can be switched off in dialog
Options/General Settings...
by deselecting checkbox On selection in Survey View.
The maximal number of open base windows in daVinci is 64.
Scaling
Used to set the graph visualization scale to 100%.
Used to set the graph visualization scale to the maximal rate
where the graph is completely visible in the base window.
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 in dialog
Options/Layout Dimensions....
Getting Informations
This operation displays the
graph info dialog
to get statistic informations about the currently visualized graph.
This operation shows a dialog window with
daVinci product informations.
