A Summary of the Graphic Indicators
A blue dashed-line rectangle, with or without handles, indicates a selected element or data frame.
Multiple elements or data frames can be selected by clicking while holding down the Ctrl key, or by
dragging a box.
❏
A line of black dashes around a data frame indicates that it is the active data frame.
❏
Just for completeness: A hash-mark border around the active data frame indicates that the frame is
“in focus,” which means you can edit what is in the data frame in the Layout View. (Normally you can
only edit within a data frame when you are in Data View. This is a subject for later.) If you double-click
a data frame, you put it in focus.

Tinkering with the Map—Scale Bars
17.
Make sure POINTS is the active data frame. Using the Layout toolbar, zoom in on the scale bar.
What number appears at its left end? ___________. Right end? ___________. Flip to the Data
View.
18.
Now select the other Zoom In tool—the one on the Tools toolbar. Drag a box around the points
that make the “P.” Go back into Layout View and look at the scale bar. Now what are the
numbers at the ends of the scale bar? ___________ ___________. Now select Zoom Whole
Page. Notice that you have made the “P” in the POINTS data frame much larger, and that the
change was reflected in the legend of the scale bar.
19.
Flip back to the Data View and zoom to the some_points layer. As you return to the Layout View
you can see that the scale bar has changed back to about the original number.

20.
Click on Zoom Whole Page. In the Layout View, select the POINTS data frame. Drag the box
larger. The box becomes larger but the contents stay the same size. Move the borders of the
box back. Now use the Zoom In tool on the Tools toolbar—making the ”A” larger. Note that the
scale on the Standard toolbar changes. Also the scale on the map legend changes.
There are three ideas to be understood here:
The scale bar dynamically keeps up with the true map scale. It may not appear so on the screen, but
it will be pretty close to right when the map is printed out or when you select the Zoom To 100% (1:1)
button.

The
scale
of the geographical elements shown on the map is controlled by the Tools toolbar buttons
and by the size of the data frame on the layout, while the
portion
of the map shown on the screen is
controlled by the Layout toolbar buttons.

If at any time the geographic elements disappear from a data frame, click on the Refresh View button (next to the
Layout View button). If that doesn't restore the image, drag the dividing line between the T/C and the map viewing
area well to the right over all the data frames, let it go, and then drag it back to its original position. Another trick to
get around this problem is to fetch the properties of the data frame and click on a tab or two. This problem appears to
have been fixed in version 10.1
