The visualization behavior of a layer is base on its legend scheme. The legend scheme of the layer could be edited with ¡®Legend¡¯ option in layer property dialog.

 

Double click the colored rectangle under ¡®Symbol¡¯ column to open a ¡®Symbol Set¡¯ dialog.

 

Now change ¡®Fill Color¡¯ and press ¡®Apply¡¯ button in ¡®Legend Set¡¯ dialog, the color change is viewed in map window.

There are three legend types in MeteoInfo.

²        ¡®SingleSymbol¡¯. All shapes of the layer are set in one same symbol.

²        ¡®UniqueValue¡¯. Each shape of the layer has its own symbol.

²        ¡®GraduatedColor¡¯. The shapes are grouped according their values an each group has its own symbol.

For example, after you change the legend type to ¡®Unique Value¡¯ and select the ¡®Field¡¯ to ¡®CNTRY_NAME¡¯. After press ¡®Apply¡¯ button, the map data will show as follow figure.

 

The legend setting could be saved as a legend file with .lgs extension. And the legend file could be loaded also. Under ¡®UniqueValue¡¯ and ¡®GraduatedColor¡¯ types, some tools could be used to add/remove and move the break in the legend set. The legend changes will be saved to the layer only by pressing ¡®OK¡¯ button.
