Symbols

Symbol-analyses visualize data with pixel graphics. Depending on the analysis subtype, one symbol is created per area or per data set. The analysis type determines the freedom in symbol display.

The subtype decides whether a symbol is created per area (Area based) or per data set (Location based).

Selection of the analysis type and the data basis

The Analysis type decides whether a symbol is generated per area (area-related) or per data set (location-related).

You can find out how to link data with the map here.

  • Via the Advanced button you can specify whether the analysis should consider an existing clip maps in the calculation of classifications - more about Analysis reference.

After the selection of the analysis type and the data basis the symbols are inserted directly into the map after clicking on Ok.

Properties of location symbol

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.

First of all, the symbols in the map have a uniform symbol shape, color and size - they are therefore not influenced by no data column. Color, symbol and size can be changed in the respective subsections.

Control symbol shape, color and size from different data columns

First select symbol, color or size a column in the different sections.

  • With a area-related analysis you can additionally determine aggregation of the data of the selected column. This specifies the rule how data are combined if several data are available for an area.
  • The Format option is only available for area-specific analyses. Normally, the formatting of the selected data column is also used for the analysis result; this is always the case for site-specific analyses. For certain aggregation procedures (for example, number of values), however, this formatting cannot be used meaningfully. You can define a new formatting here, which is used in legends for this analysis, for example.

  • Under Statistics you can display statistical information (e.g. number of data records, min., max.) for the selected column - click on the button in the field next to Statistics.

Settings for changing:

Let only one column control the properties of the symbols

If you want the properties of the symbols in form, color and size to be controlled only by one and the same column, you must first link the analysis. You can find the Link Color, Size and Symbol function either in the Properties of the analysis (at the bottom of the Properties window) or in the context menu for analysis in the control window Contents. Then the structure of the Properties window changes.

Select column

In the Display area you can now select a Data column which controls the characteristics Symbol, Color and Size simultaneously. These are combined in a value class list.

Number of classes and classification method

In the middle area, enter Classes, the Count for classes, and the method of automatic Classification or set here to User defined to edit your own classes. In addition to Analysis range, you can also specify an interval within which the values are to be taken into account. Values outside the interval always fall into the residual class "unclassified".

Editing Classes

In the lower area you can define the display styles for certain value intervals (classification) of the analysis. Here you can use various commands to edit Classes and various design features (color, symbol, size).

  • The design features and class boundaries can be edited by double-clicking in the relevant cell. For example, you can select a symbol from the program directory by double-clicking on the symbol for the relevant class.
  • for further information on editing value classes, symbols, colors and sizes, see here.

Determine the details of the analysis

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

Labeling

The symbols can be labeled on the map (e.g. with the name of the district to which the symbol refers). Open the properties of the Symbol analysis in the content window > section 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. For instance, the location symbol for each individual customer can be given a name and customer number. This makes it easier to identify customers on the map.

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

Create tooltips for analysis

As an alternative to labeling symbols, you can display tooltips when you move over the symbols on the map. Displaying tooltips instead of labels is a better approach, especially for a large number of locations.

Note: You can find out how to implement tooltips here.
