6.1.8 Zooming & Panning in a plot
If you want to investigate details in a plot, you can zoom in on the area of
interest.
Permanent zoom Using the property editor is one way of doing this by increasing minimumvalues
and/or reducing maximum-values on the horizontal and/or the vertical
axis of the plot. Although very accurate, this approach require that you enter
four new boundary limits for the plot, and switching back to the full view
requires you to change all four limit-values once more. Consequently this
approach is only recommended, if you wish to zoom in permanently on a
specific area of your plot.
Zoom out x 2 To get a better overview of a plot, you can quickly zoom out: right-click in
the plot window and select Zoom out x 2.
Temporary zoom If you wish to temporarily zoom in on a specific area, and do not require the
limit-values to be so accurately defined, a different approach can be used:
Simply press the Ctrl- or the Shift-key on your keyboard, and hold it down
while selecting a rectangular area in your plot using the mouse. The area is
selected by pressing the left mouse button in a corner of the intended zoomarea,
and then drag the mouse to the opposite corner. When you release the
left-hand mouse button in the opposite corner, the system will zoom in on
the area selected.
Zooming out You can zoom in repeatedly going into still finer details of your plot, and
zooming out again can either return you to the full view or to the previous
level of magnification: Right-click inside the magnified plot, and select
either Zoom Out or Zoom Restore from the context menu that appears.
Alternatively you can use the corresponding keyboard shortcuts Alt-Z or
Ctrl-Alt-Z to respectively zoom out one level, or return to the full view.
Panning Whether or not you have zoomed in on a plot, you can pan up, down, left or
right, using the arrow-keys on the keyboard. Pressing the up or down-arrow
will shift the plot up or down in steps of 20% of the current plot height, and
similarly pressing the left or right-arrow keys will shift the plot left or right
in steps of 20% of the current plot width.
Restoring a plot If you loose track of your plot having used several zooms and pans, you can
always return to the settings in the property editor by running the plot object:
Select the plot and press the run-key ( ) on the toolbar, or use the shortcut
key F5. Right-clicking the plot object in the project explorer and selecting
Run from the resulting context menu has the same effect.
Reading values The Advanced Graphics Add-On can also help you reading numerical
values in a plot: Left-click the mouse while pointing somewhere within the
plot area. The coordinates of the current cursor position will then be read out
in the status bar in the lower right-hand corner of the screen.
Please be aware that within the Windows operating system, the position of
the mouse cursor is measured in screen-pixels. This limits the resolution
achievable when reading values in a plot, and to improve the accuracy of the
reading, you may wish to maximise the plot to fill the entire workspace.
