Area Hatching
While the standard area shading can only represent one data value per area, the Area hatching analysis offers the possibility to display several data entries per area simultaneously.
The requirement for this type of analysis and data presentation is the availability of several different data sets in the same territories. A potential area of application is the presentation of election results or the overlapping of employee sales territories.
Note: In this analysis, make sure that the number and width of hatchings are not too large, as otherwise the clarity of the presentation may suffer.
Creating the analysis and selecting the data base
You insert the analysis via the control window Data per Drag&Drop. First select the appropriate table column for the analysis and drag it to the Map. Select the icon for surface hatching and set the appropriate level and assignment. By pressing Ok you confirm your selection and receive a finished hatching, which can be adjusted individually afterwards.
Note: You can also insert your analysis via the menu bar Analyze. You get an analysis without predefined settings and value classes.
- What does the assignment result tell you?
- Would you like to place your data on the map using geographical coordinates? So the The Data Input for an Analysis.
- The Advanced button allows you to specify whether the analysis should consider an existing clip map when calculating classifications - more on the analysis reference.
Determine the properties of the area hatching
When inserting a new area hatching, all areas for which a data set exists in the selected table are first colored uniformly in the map. The Color and Hatch Width of the area hatching can now be edited in the opening Properties window. You can also access the properties if you want to edit existing analyses.
The colours of area hatching
The color of the hatches is always controlled by a data column:
- First select the data column be evaluated in colors tab of the properties of the analysis. The colors of the area hatching can be either classified, continuous (only with Number columns) or differentiated by a given color value (adjustable during data evaluation).
The width of the area hatching
The width of the area hatching can either be set independently of the data or controlled by means of a data column.
If the hatch width is not data controlled, a maximum of one bar per contained value class is drawn per area. If several values belonging to one area fall into the same color class, only one color bar is drawn for these values (qualitative display).
Example: An area has three values, two of which fall into a red class and one into a yellow value class. The territory will thereby be Hatch in red and yellow bars of equal width.
- Under hatch width, enter the desired width in pixels.
However, if the hatch width is data-controlled (this also applies if only one value class is available), one bar is generated per value (quantitative display). In this case, bars of the same color (bars whose values fall into the same color class) are placed next to each other. The width of the resulting total bar is the sum of the widths of the individual bars.
Example: If two values of an area each lead to a red bar, and the first bar is 1 cm wide and the second bar 0.5 cm wide, a 1.5 cm wide red bar is displayed. All other colored bars are displayed next to it.
- First, always select the Column in the section Hatching Color and the Hatch Width .
- The hatch width can be differentiated depending on a data value classifiedor proportional. Please enter the width via the number of pixels per strip.
- Classified: Through the creation of classes, you can define the Hatch width for a value interval.
- Proportional: This allows you to specify a continuous width curve that is calculated directly from the analyzed data values using a factor.
- As with the property characteristics you can limit the analysis area or define a color gradient outside of the analysis area.
Determine the details of the analysis
In Details you define other (non-data-dependent) properties of the analysis.For example, set the alignment of the hatching (horizontal, vertical, oblique, etc.).
Visibility | |
General |
Here you can control the visibility of objects and elements. |
Scale range |
Here you can set whether the selected object or plane should be visible at each scale. Or you can specify the scale or zoom level at which the object or layer is visible. |
In reports |
In Reports there is the possibility to change the environment only partially to zeigen. You can use this property to specify whether the layer is also visible outside the report area in this case. |
Size adjustment |
Specify here how the size of a symbol or diagram behaves when the map scale is changed. This can change e.g. after zoom within the map, after setting a clip map or within a report, because only a part of the map is displayed. More about Size adjustment at auto zoom. |
Alternating visibility group |
Set a group for mutual visibility here. If the element is to be made equally visible with other elements, you must use the same name for the visibility group. |
Simultaneous visibility group |
Set a group for simultaneous visibility here. If the element is to be made mutually visible with other elements, you must use the same name for the visibility group. |
Common | |
Type of Shading | Here you can select whether the color of the areas full area or only as edge color should appear. With this option, loosened maps are possible, which allow not only the analysis of the surface coloration but also a further evaluation, without the map appearing overloaded and not really readable. |
Width of the Colored Border |
Here you can set the width for the edge coloring in cm . |
Comment | Enter here a comment for the display of the workbook in EasyMap Xplorer. The comment is also displayed in EasyMap as a tooltip in the control window Contents. |
Hatching | |
Type | This option lets you specify the type of hatching. You can currently choose from four different gradients. |
Create tooltips for analysis
When crossing the colored areas on the map, you can display context-sensitive information about them.
Note: You can find out how to implement tooltips here.
The commands of the context menu
You can call up its context menu by right-clicking on the analysis in the control window contents. The context menu offers actions that can be performed on this analysis.
Transfer Selection to |
Transfers the current selection geographically to another object. Details... |
Visible |
Shows whether the object is visible and allows switching the visibility. |
Order |
Here you can change the selected element in the character sequence. Another option is to drag and drop the selected element within the content view. |
Input Data... |
Displays the data settings for the selected analysis. You can use this command later to change the connection between the analysis and the data. Further information can be found here. |
Show Results Table | Displays the results of the selected analysis in a table. |
Ignore filter |
Defines whether an Analysis filter should be considered or not. |
Restore defaults |
Undoes all manual changes to this layer. |
Clip Map |
Here you can define a different clip map for the analysis. |
Map XY |
Here you will find various commands for the map. |
Copy |
Copy the object (if necessary with all subobjects) to the clipboard to paste it elsewhere. The object can be inserted in other applications as a graphic, or inserted in EasyMap as a copy of this object using the Insert command. |
Paste |
Pastes the contents of the clipboard into this object as a child object. |
Delete | Deletes the selected element. (See also: delete objects) |
Rename |
Changes the content view to an edit mode to give the object a new name. (This can also be achieved by clicking on an object that has already been marked.) |
Properties... |
Opens a properties dialog in which you can edit the Properties of the selected object. If several objects are selected, many properties can also be changed simultaneously for these objects. |
