Setting the display properties of a standard bar

For links and connectors, you can display the values of an attribute of the particular network object by a bar. For desire lines, the values of an OD pair attribute are displayed. With turn volumes, the values of a (main) turn attribute are displayed.

1.  Make sure that the appropriate page has been opened in the Edit graphic parameters: Network editor window:

  • Links: Links > Bars > Display
  • Connectors: Connectors > Bars > Display
  • Desire lines for zones: Desire lines zones > Display
  • Desire lines for main zones: Desire lines main zones > Display

2.  If required, add another column for a bar (Defining one or multiple bars).

3.  Click in the header of the column for the desired bar.

Note: You can directly edit some of the display properties in the column. The Edit function provides access to the display properties.

4.  Click the  Edit icon.

The Edit bar <no> window opens.

5.  Select the Draw this bar option.

6.  In the Bar type section, select the option Standard bars.

7.  Select the Scaling tab.

8.  Make the desired changes.

Description

Scaling attribute

In a separate window, you can select the attribute which is to be displayed as a bar when clicking this button.

Scaling

Maximum bar width

Maximum bar width in mm

Note

With maximum width = 0, no bar will be displayed. The label, however, can be displayed.

Use minimum width

If the option has been selected, very thin bars, which cannot be displayed adequately with their actual values, are drawn in the smallest width that can be displayed. A tooltip displays the attribute value range in which the minimum width is used.

Note

Alternatively, for line and path bars, you can define substitute bars on the Fill style tab.

Manual scaling

If this option has been checked, you can define the value range by bar: Enter the absolute values for the bar display. The lower scaling limit corresponds to the minimum bar width, the upper scaling limit to the maximum bar width.

The bar width is identical for a bar representing a negative attribute value and a bar representing the respective positive attribute value. The scaling range has to be adjusted accordingly: For attribute values in the range between -200 and +100, enter 0 - 200 as scaling range.

If the attribute value of an object is less than the lower scaling limit, the bar will not be displayed. If the attribute value of an object is greater than the upper scaling limit, the bar will be displayed in the maximum width.

Notes

For the optimum display of the bar, you should adjust the input limits to the displayed minimum and maximum values.

For a constant bar width, enter the same value in both entry fields.

Negative and positive values can be distinguished by the fill colors (Fill style tab).

Automatic scaling

If the option has been selected, the value range goes from 0 to the calculated Network maximum that has been determined from the attribute values and which is multiplied by a user-defined factor between 0.0 and 1.0.

9.  Select the Label tab.

10.  Make the desired changes.

Show title

If this option is checked, another text portion will be added to the bar label:

  • Name of the scaling attribute: Next to the value, the network object name will be displayed.
  • Text: Next to the value, the text entered in the field will be displayed.
