Map Renderers

You use a map renderer to determine how BW data is displayed in a map layer.

There 11 different map renderers in the BEx Web Application Designer. These renderers are divided into three different classes:

Class 1: Renderers that relate to polygonal areas (static geo characteristics). They display the following:

• Color shading (COLORSHADING or CS)
• Bar charts (BAR)
• Pie charts (PIE)
• Pie charts (split) (SPLITPIE)
• Pixel density (DOTDENSITY or D_DENSITY)

  For these renderers, the static geo characteristic must appear in the related data provider in the rows and the values to be displayed in the renderer must be in the columns. You can use hierarchies in both cases. No other characteristics other than the geo characteristics must appear in the rows. No key figures must appear in the rows. You can use several characteristics or key figures in the columns.

Class 2: Renderers that relate to locations (dynamic geo characteristics). They display the following:

• Symbol (SYMBOL)
• Symbol (size-dependent) (SIZEGRADUATEDSYMBOL or SG_SYMBOL)
• Symbol (color-dependent) (COLORGRADUATEDSYMBOL or CG_SYMBOL)
• Bar charts (BAR)
• Pie charts (PIE)
• Pie charts (split) (SPLITPIE)

  For these renderers, the dynamic geo characteristic must appear in the related data provider in the rows. You must have also selected the Longitude and Latitude display attributes to be displayed. No other characteristics or key figures must appear in the rows. Only the first column is considered by the symbol renderers. The renderers bar chart, pie chart, and pie chart (split) consider all columns.

Class 3: Renderers that display relationships between two locations (dynamic geo characteristics):

• Line (LINE)
• Line (size-dependent) (SIZEGRADUATEDLINE or SG_LINE)
• Line (color-dependent) (COLORGRADUATEDLINE or CG_LINE)

  It is important to have at least three map layers for these renderers. You define start points in one map layer and end points in another map layer. The prerequisites described in class 2 are also valid for both of these map layers. The third map layer contains the relationship between the dynamic geo characteristics of the start points and the dynamic geo characteristic of the end points, that is, both characteristics must be in the rows. The same prerequisites described for class 2 apply to the columns here.

To display the BW business data on individual map layers, you have to assign a map renderer to each map layer in the BEx Web Application Designer and determine the properties for this renderer.

To select a map renderer, use the parameter MAPLAYER_LIST of the Map Web item, underRenderer.
