Maps are used to visualize data in an easy and intuitive way. A map is a symbolic visual illustration of areas, regions, and themes. SAP Visual Business supports analytic maps and geographic maps.

The analytic map shows regions such as continents or countries. Another term for this kind of map is a choropleth map.

In the context of a business application, the analytic map is useful for displaying quantitative or qualitative data by coloring various regions.

The analytic map is the best choice if you want to visualize region-specific values, such as for visualizing the sales revenue for different countries.

The geomap displays geographic elements like roads, cities, forests, and other details and is mostly used for navigation. In the context of a business application, a geomap is useful for displaying points of interest, area objects, or other charts over the map.

The geomap is the best choice if you have location-based data, and you want to show a road map, satellite map, or another specialist map in the background. For example, a geomap is good for visualizing the revenue of stores.

Components

A map can include any of the following elements:

• Toolbar (optional)
• Navigation tools:
  • Legend (optional)
  • Navigation control (optional) and scale (optional)
• Symbols for improved visualization of use cases:
  • Spots (optional)
  • Labels (optional)
  • Circles/geocircles (optional)
  • Areas (optional)
  • Routes (optional)
  • Container (optional) – here an arbitrary SAPUI5 control or chart can be shown on a map

Toolbar

If you need a toolbar, use the one provided by the ChartContainer SAPUI5 control.

Navigation Tools

Legend

A panel containing a legend is displayed and expanded by default. You can also collapse, expand, hide, or move the legend anywhere on the map if necessary.

Navigation Control and Scale

Symbols for Improved Visualization of Use Cases

Spots

You can use spots to visualize specific locations on the map. There are five different types of spots: the default blue spot without any semantic value and the four semantic spots with icons. Adding numbers or text to a spot will replace an existing icon on the spot.

If you want to use a number with more than one digit, or text with up to five characters, you can use the relevant predefined spots that are provided. Spots are available for numbers containing up to one, three, and five digits. For text, spots are available for up to five characters (in all five colors). Use the label for numbers or text that exceed these limits. Ensure that numbers and texts on spots are not translated; if this is necessary, use labels.

Labels

You can use a label to provide more information about a symbol. The label supports multiple lines and should be equally aligned for a group of symbols; for example, use the same alignment for all labels of spots.

For routes, the position of the label adapts to the map section. In other words, the label moves on the route so you can always see it at any zoom level. If a label is not sufficient, we recommend you use a container with the appropriate SAPUI5 control.

The label is available in five different colors: the default (neutral) white label, and the semantic labels. The label adapts to the number of digits, and the content of the labels is translated if necessary.

Circles/Geocircles

You can use circles to visualize specific, quantitative parameters, while geocircles can be used to visualize specific sizes or measures. The difference between circles and geocircles is as follows:

• Circles: Radius is given in pixels – constant screen size.
• Geocircles: Radius is given in meters – constant size in reality.

A use case for circles on a map might be to show the size of the biggest towns in a region or the revenue of a company per production location.

Areas

Routes

You can visualize routes.

Container

You can use containers to display an arbitrary SAPUI5 control on the map. The map control only provides the container. The app team can personalize the container (in terms of fill, border, and size) and add an arbitrary SAPUI5 control.

Behavior and Interaction

Zoom

There are four ways of performing a zoom:

• Navigation tool: use the navigation controls to zoom in and out.
• Mouse wheel: use the mouse wheel to zoom in and out.
• Gesture: on a touchscreen, use the ‘pinch and spread’ gestures.
• Keyboard: use the ‘+’ and ‘-‘ keys to zoom in and out, or use the ‘Z’ key to use the rectangular zoom.

Select

You can choose different selection modes: single selection to select a single item, and rectangular selection to select multiple items. You can also use the Shift key to add items to an existing selection, and the Ctrl key to select/deselect items.

Single Selection

This is the default selection mode. You can click your mouse button to select an object, while at the same time deselecting a previously selected object.

Rectangular Selection

You can switch to rectangular-selection mode by pressing the ‘R’ key. The cursor changes and you can use your left mouse button to draw a rectangle. Each object that lies within the rectangle is considered selected. Press the ‘R’ key again to leave this selection mode and return to single-selection mode.

View Tooltip

For desktops, a tooltip is enabled to provide additional information about the symbol.

Keyboard Shortcuts (desktop only)

Colors

For general rules about using colors in charts, see Chart – Color Palettes. You can define colors programmatically for each region.

Default Colors

Water and regions have default colors. The color of water cannot be changed. The color of each region can be changed individually. Keep the default color if the region has no data.

Regions Only

Colors from Qualitative Palette

Use colors from the qualitative palette to highlight particular regions. Use the first color of the qualitative palette. Also use colors from the qualitative palette to separate regions into distinct groups. Note that colors from the qualitative palette have no semantic value. For example, do not choose a color because it is blue or green as the hue associated to these colors may change in the future or may be customized by the customers. Start by using the first color and then the second color and so on, unless there is a good reason for not doing so. If there is no data for a region, keep the default color.

Colors from Sequential Palette

Use colors from the sequential palette to encode quantitative differences, that is, to visually represent the idea of level, progression, or graduation. If there is no data for an item, keep the default color. See the section on How to Use the Sequential Palette in the Chart – Color Palettes article.

Colors from Semantic Palette

Use colors from the semantic palette to show that data points are bad, neutral, or good. If there is no data for an item, keep the default color.

Map with Circles/Geocircles

If you need to display circles over a map and use sequential colors for the regions, use the sequential palette with the following colors:

See the section on How to Use the Sequential Palette in the Chart – Color Palettes article.

Guidelines

General Guidelines

• Use the sequential color palette if there are no more than six different states. If you have more than three states, we recommend that you use the tooltip or legend in addition to the colors to provide detailed information. The reason for this is that the contrast of the colors for maps is too low to differentiate all colors at first glance. The sequential palette aims to highlight the most interesting states by using the darkest and the lightest color.
• Use the qualitative color palette if you want to visualize various states that are independent of each other, such as election areas.
• Use the semantic palette if you want to express good versus bad states, such as with revenue figures.
• If you want to display two regions with specific parameters, a combination of coloring the regions and using circles would be the best choice. Avoid overlaps by providing different aggregation levels at different zoom levels. Note that there could be problems with relating a parameter to the radius of a circle because a user will compare the area and not the radius. The area has a quadratic relation to the radius. Consequently, a smaller number looks very small and cannot be visually compared with other values.

Embedding

To place the map on a page together with other charts, use the same guidelines as for the VizFrame charts, as explained on the Chart Toolbar and Chart – Embedding articles.
