It is important to choose an appropriate map type for the type of data that you are presenting. This will determine how well the data can be interpreted when put in map form.
Each map type has unique characteristics to help you visualize your dataset. You can use any map type to display your data, but your data will be easier to read when you use a map type that is suitable to your data, based on what you are trying to show in your report.
The supported map types are:
Similar to the Graph's Scatter Chart, it is used to display a correlations between two sets of values. The main difference is that the first values set is defined using a geographical coordinates, which will position every data point onto the map. The second values set is used as a measure and displays a bubble with variable size depending on the measured value, i.e. the differences between the data points are based on the size of the point. The larger the point is, the larger is the difference between the two data points.
Such a chart is used to display grouped data as a Graph's Pie Chart on every data point. As with the Point map type, the data point coordinates are defined by the GeoLocation group. The analytical data, needed to create the pie chart, is obtained using the child groups of the GeoLocation group. You may learn how to setup such a map in the article How to Setup a Map Using the Map Wizard.
Identical to the Pie chart type, with the only difference that the analytical data is presented using the Graph's Column Chart. A more advanced example that shows how to create such a map and add some additional extras, can be found in the article How to Create a Map with BarChart series using CSV data source.
A thematic map that uses graded color differences to display a measure over predefined regions or areas. It is one of the most popular ways to visualize how a measure varies across a geographic area. An example how to create a Choropleth map can be found in the article How to Setup a Choropleth Using the Map Wizard.
The Choropleth item is basically a Map item with a special kind of series and groups. To create a choropleth map, there is no need to configure a Location provider or use a GeoLocationMapGroup to obtain the coordinates of the data points. Instead, it uses a ShapeMapSeries instance, whose major distinction from the other Map series is that they define the source which will be used to provide the spatial data. This source can be either a string, formatted in compliance with the Well-known text/Well-known binary standards, or an ESRI Shapefile.
To achieve better appearance, the Map item can define a Tile Provider which will draw an image of the requested map extent as a background layer onto the plot area.
