Use cross-section values |
Note If an undirected value to be displayed is averaged, it is automatically divided by two, so that half of the undirected value counts as the upper limit for the scaling. If, for example, the scaling range is 1-1000 and the bar width is 10 mm, an undirected value of 2000 is displayed with a volume of 1000 on each side and a bar width of 10 mm. |

Draw bars only on active turns |
If the option has been selected, bars are not drawn for passive turns. |
|
Draw bars also on blocked turns |
If the option has been selected, bars are also drawn for closed turns. |
|
Regard all turns |
If the option has been selected, bars are drawn on all turns that correspond to the above options. |
|
Draw bars only on selected turns |
If the option has been selected, you can hide bars of turns with specific attribute values. Use the button below the option to select the desired attribute. Click the Edit button to create the classification (Displaying classified objects based on attribute values). Via the check box in the Draw column you decide whether the turns of the particular class are to be drawn. Use layer order If the option has been selected, you can set up the order of drawing for the bars by class. The order is specified via the numbers in the Layer column. This column appears as soon as the option is checked. By default, the network objects of the various classes are drawn in the order as specified by the order of the classes in the list. |

Positioning of turn volumes at main nodes |
If the network contains main nodes, you can position the associated turn volumes as follows. At turn volume circle If the option is selected, turn volumes at main nodes are displayed only inside of turn volume circles. At the cordon nodes If the option is selected, turn volumes start directly at the cordon nodes of main nodes. They are thus independent of the radius around the point object of the main node. This way, volume bars, for example, may be drawn continuously in a network with main nodes. |
|
Circle display |
Draw circle If this option is checked, a circle is placed around each selected node. In the circles, the turns will be displayed. Simple fill If the option has been selected, all circles around the nodes are displayed with the color selected in the Color section. To edit the color and/or fill style, click in the field (Editing the properties of a closed polygon). Smooth color transition If the option has been selected, the circles around the nodes are displayed with a color gradient.
