Workspace Manager Menu Commands
MapXtreme v7.1 420 Developer Guide
The Previous View and Next View commands can be used together to toggle back and forth
between two views of your map. These commands are also available as tools on the toolbar.
Preserve Scale/Zoom
Use the Preserve Scale and Preserve Zoom commands to keep the zoom and/or the scale the same
as you change the size and shape of the map.
Redraw
Use the Redraw command to redraw the map.
View Selection
Use the View Selection command to zoom in or out on a selected object or objects.
Theme Wizard
You can create feature themes and label themes via the Map > Theme Wizard menu command.
Feature themes include ranged, individual value, dot density, graduated symbol, and pie and bar
charts. Label themes include ranged and individual value.
If your map includes at least one set of labels, which are displayed in a label layer, you can create a
label theme. A label theme assigns different label styles (colors, font size etc.) to each label, based
on the data in your table. For example, use a label theme to show the prominence of locations over
others. A ranged label theme groups labels based on a similar data value, such as population. Cities
that fall within a certain population range are labeled using one style, while cities in other ranges are
labeled in another style, typically a less prominent style to indicate city size without having to label
using the population value.
The Theme Wizard walks you through 3 dialogs to create your theme.
To create a theme:
1. Choose Map > Theme Wizard.
The Create Theme: Step 1 of 3 dialog box appears.
2. Select either a Feature theme or a label theme, and choose the type of theme you want to
create.
3. Click Next.
The Create Theme: Step 2 of 3 dialog box appears.
4. Select the table you want to shade.
5. Choose the data you want to use. Select either a column from the table that contains the data, or
select Expression to use an expression to derive the data you want from the table.
6. Click Next.
The Create Theme: Step 3 of 3 dialog box appears. Here you can customize theme type
settings, styles, and the legend. (See
How to Apply Translucent Effects to Themes for
instructions on applying translucency effects to a thematic map.)
7. Click Apply to apply the customized settings.
