A map is a complex output control that allows users to visualize geographic data and its relationships. You can choose from hundreds of available maps and add location data into your application’s web interface. Each map must be associated with a Table Named Range (TNR) from the workbook.
Inserting a Map
To create a map, drag and drop a Map module into your page in the User Interface Designer.
Once placed, click on the chart to define its properties from the properties menu. Begin by selecting the Table Named Range (TNR) that contains the target map data from the Table Named Range selection. This range should include both the data and the column headers for the map.
For example, when creating a map for the world population, both the country names and the population data should be included in the selected Table Named Range (TNR).
The properties of the map control are outlined below.
You can select from four distinctive map types:
- Standard Map: The most common map type in data visualization, a standard map shades the map area to display quantitative values.
- Cartogram: A cartogram map uses circles or squares of varying sizes to show regions in accordance with a quantitative value associated to them. This map type is best used to highlight the values of outlier regions, instead of their actual size.
- Continuous Cartogram: A continuous cartogram plots the selected measure on a map by scaling the land borders depending on the selected data field.
- Tile Map: Tile map uses circles, hexagons, or squares instead of the actual land borders to depict the regions. This view is quite useful for showing small regions that are otherwise difficult to read on a regular map.
- Density Map: Density map is a type of heat map which plots values that match the selected latitude and longitude fields. Plot points will have different colors based on the magnitude of each value shown.
- Location Map: Similar to a Density map, Location map plots data on a latitude and longitude basis. The data shown on a Location map will have circles of different sizes, which signify the each value.
- Route Map: Route map can plot a path from point A to point B (or C, and D, and so on), using a numeric or date field. This effectively sorts longitude and latitude data in the order that they appear on the order field.
Sample images of the variations are depicted below.
Maps with Region Name Input
Maps with region name inputs are maps that require you to select a region, add fields that contain the corresponding region names, and the data to be visualized. The geographic names that come from your data fields must comply with the international naming convention. Sample images of the variations are shown below.
The scope of the map (i.e. region, country, state, or city maps) can be selected from the Map Name menu.
The data column containing the corresponding area names can be selected under the Label Field property.
The target values to be displayed against the area names will be coming from the Value Field data. Each Map Type will behave differently when displaying this data, in accordance with the map types.
- Standard maps and Tile Maps will show color-coded values.
- Cartograms will show value based on circle diameter.
- Continuous cartograms will distort area shapes based on value.
Maps with Latitude/Longitude Input
Maps with latitude/longitude input are maps that require you to define where data is going to be plotted on the world map by defining the latitude and longitude of each data item. Sample images of the variations are shown below.
This field is only applicable for the Density Map, Location Map, and Route Map. The named range containing the latitude (horizontal placement) of the values to be plotted in a numeric format.
This field is only applicable for the Density Map, Location Map, and Route Map. The named range containing the longitude (vertical placement) of the values to be plotted in a numeric format.
The target values to be displayed against the area names will be coming from the Value Field data. Each Map Type will behave differently when displaying this data, in accordance with the map types
- Location Map will show value based on circle diameter.
- Route Map will show a path in the order of data items.
This field is only applicable for the Route Map. The items in the Group Field named range selection will determine how the coordinates will be grouped.
This is an optional field, and should only be selected if you want to display multiple routes. The coordinates will be grouped into multiple paths based on the corresponding Group Field items.
This field allows the visualization to be separated as groups by the data.
This is an optional field, and should only be selected if you want to display multiple visualizations.
Title, Color and Fonts
Entering text into the Chart Title box will print it on the map area. The title text properties can be changed from Title Color and Title Font Size options. Background color can be changed using Background Color option.
The height of the map. Map heights can be set manually within a range between 200 and 1000 pixels. Alternatively you can check Use auto-calculated height property.
The color set of the map. You can customize your maps’ colors as you desired by clicking to Edit Color Scheme button. If a color set is not selected then it will use default color set from the Edit Application page.
You can customize your map by pressing the blue Edit buttons on the bottom of the right hand menu.
- Edit Color Scheme determines the color set of the map.
- Edit Legend properties affect the labels and colors of the map legend.
- Edit Tooltip options determine the mouse-over text format.
- Edit Labels properties affect the labels and colors of the map.
