Pie Charts

Pie charts are essentially suitable for distributions and percentages representation, but less representative for comparing absolute values.

Creating a New Analysis

The analysis circuit diagrams insert data via the control window Select one of your data columns and place it onto the map using drag and drop.

First, you decide the type of analysis and its subtype. Wing chart analysis has segments arranged at the same angle with their radius representing the value. Pie chart segments display in a circle with their angle representing the percentage. Both Wing and Pie charts have similar settings.

You can choose between a site-related and a area-related representation of the diagrams. The analysis type determines whether a diagram is generated per area (area-related) or per data set (location-related).

After selecting the analysis type, continue with the selection of Layer and Assignment.

Note: You can also insert your analysis via the menu bar Analyze. You get an analysis without predefined settings and value classes.

Set Properties of the Analysis

Properties refers to all settings for calculating and displaying the analysis. You can select certain columns of the previously defined table to control certain aspects of the display (for example, the color). You also reach this settings dialog if you want to edit existing analyses.

Chart

Under Diagram you define which data the diagram should display. You can also specify the coloring and size proportions of the diagram and other diagram options.

Determine the details of the analysis

In Details you define other (non-data-dependent) properties of the analysis.

For example, you can influence the sorting of the sectors under the entry style , or under Data Labeling you can have the individual sectors labeled with values or percentages.

Labeling

In addition to the labeling of the sectors, each chart can also have a label that applies to the entire chart (for example, the name of the area to which the chart refers). The settings for this are defined under Labeling.

  • If the analysis area-related is created, EasyMap offers the possibility to label each symbol or object with the name or number of the corresponding area (geographical data).
  • With the analysis subtype Location-related, however, only the columns of the data table used as the data basis for the analysis can be used for labeling.

Note: How to insert diagram texts and how to influence the display of the texts can be found here.

Tooltip

When driving over the diagrams on the map, you can display user-defined information about them.
