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.

Element	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.

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.

General label settings	Hide if (absolute) value <= If this option is checked, no label will be displayed if the absolute attribute value is less than the entered value. Priority in case of a lack of space Enter a number to indicate the priority of the label of this bar. If several labels shall be displayed next to each other along a polyline object that is too short for the display of all labels, the label with the lowest priority will be faded out first. 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.
Label type	Value of scaling attribute If the option has been selected, the value of the attribute selected for the definition of the bar scaling is displayed (Scaling tab). Class name (only for classified fill) If the option has been selected, the name of the class selected for the definition of the fill style will be displayed (Fill style tab). Value of the fill attribute (only for classified fill) If the option has been selected, the value of the attribute selected for the definition of the fill style is displayed (Scaling tab).
Display format for attribute value	Show attribute value If the option has been selected, the attribute value is displayed. Note Further settings in this section depend on the format of the value that has been selected for labeling. All settings only refer to the bar labels, they do not refer to the actual values. Multiply by Factor by which the attribute values are multiplied for the display Round to the multiple of Rounding value for the displayed attribute values Notes If you entered 100, for example, the values are rounded to the nearest hundred. Just attribute values are rounded. Class limits and class values are not rounded.
