Creating a scatter plot

For a scatter plot, you select a network object type and an attribute from it, whose values are plotted on the x-axis and the y-axis. You can display the values as a Data series using another dimension: By selecting time interval, simulation run, class of vehicles or pedestrians as data series, you form the groups for the visualization whose data you want to compare with each other. The points of each of these groups are displayed in the scatter plot with the same color.

Scatter plots cannot be combined with bar charts or line charts.

1. On the View menu, click > Create Scatter Plot.

The Create scatter plot window opens.

2. On the Data Assignment tab, select the desired data:

Network object type list box	Network object type from which you want to select two attributes for display in the scatter plot
X-axis, Y-axis	: attribute and/or subattribute whose values are to be displayed
Data series	Select the entry you want to use as a basis for forming the groups whose data you want to compare. This forms the basis for different colors, shapes as well as the legend.

3. If desired, further restrict the data based on the criteria on the Filter / Aggregation tab:

Network Objects	All: The values of the selected attributes are taken into account from all network objects of the selected network object type. By attribute: Restrict network objects to be considered based on attribute values. Select the attribute and enter the criterion for the restriction in the list box. If a criterion requires a value to be entered, a field with the default value 0 is displayed next to it, which you can overwrite. Synchronized with selection: consider only the network objects of the network object type selected in the network editor
Simulation runs	All: If several simulation runs have been performed, only the data of the selected simulation runs is taken into account. Selection: Select simulation runs to be considered from all simulation runs performed By aggregation: select the desired aggregation for each of the two selected attributes
Time intervals	All Selection: Select time intervals to be considered from all defined time intervals By aggregation: select the desired aggregation for each of the two selected attributes
Classes	All: Consider all classes Selection: Select classes to be considered from the defined classes of the object

A chart preview is displayed when data has been selected in the area on the right and the data selection is valid.

4. To apply a named chart layout in the chart, in the Named layout list box, click the desired entry (Using named chart layouts).

5. Confirm with OK.

The Create scatter plot window closes. The Scatter plot <title> window opens in the Vissim GUI. The scatter plot is displayed. Example:
