Creating Entity Colour Schemes

Although Entity Types are assigned colours during the model building phase of a LEGION project, LEGION Simulator enables you to create additional Colour Schemes based on pre-existing value ranges.

Creating a Colour Scheme based on an available value range

This task enables you to set up an Entity Colour Scheme based on pre-existing value ranges, which you have used in another Analysis or Map, or industry standards such as Fruin's Levels of Service.

Tip: To use a Colour Scheme, you must activate it in the Object Directory.

To create a scheme based on an available value range:

  1. Click or select Display > Entity Colour Schemes.

    The ‘Edit Entity Colour Scheme’ dialog is displayed.

  2. Click New to add a new Colour Scheme to the left-hand list.
  3. Type a name for the new scheme in the highlighted name box and press Enter.
  4. Click on the Colours tab.
  5. From the Metrics drop-down list near the bottom of the dialog, select a desirable metric.
  6. From the adjacent Value Ranges drop-down list, select one of the available ranges.
  7. Click the Create button.

    This creates a range of named colours, which are listed in the main panel of the ‘Colours’ tab.

  8. If required, you can rename these colours by double-clicking on their current names and typing new descriptions. You may also change the colours by double-clicking their current colours and selecting from the drop-down palette.
  9. If you wish to refine the filtering for each colour, click on the Filters tab and for each colour in your range, add new filter settings. For more information, see Advanced Filtering .
  10. Click Apply or OK to save your changes.

Creating a bespoke Colour Scheme

This section describes how to create your own Colour Scheme and apply filters to each colour. The task is broken down into two procedures; the first describes how to create colours, the second how to make them meaningful by applying filters.

To create the colours for a new Colour Scheme:

  1. Follow steps 1 to 3 of the previous task ("To create a scheme based on an available value range").
  2. Click on the Colours tab.
  3. For each colour you wish to add to the scheme, click the Add button once.

    New colours with default names are added, under the headings Name and Colour.

  4. To change the default name of a colour, double-click to select it and type a new name in its place and press Enter. Repeat this step for as many names as you want to change.
  5. To change the default colour, double-click on the colour to display a drop-down palette of optional colours.
  6. Select a colour from the palette and then click outside of the coloured box to apply the new colour. Repeat this step for as many colours as you want to define.
  7. If you want to add extra colours, remove colours or move them up or down in the list, highlight the relevant colour or colours and click the Add, Remove, Up, or Down buttons.
See the next procedure.

This procedure briefly describes how to set up bespoke filtering criteria for each colour in a colour range. For an in-depth discussion of advanced filtering techniques, see Advanced Filtering .

To apply filters to colours:

  1. Click on the Filters tab.
  2. In the Available Entity colours box, highlight one of the colours you just added. Notice the four control boxes (plus Add button) beneath the Available Entity colours.

    These enable you to define a bespoke filtering criterion to apply to a highlighted colour.

  3. Set up a filter by either typing the conditions directly into the space below the control boxes or by selecting options from their drop-down menus. Reading left to right:
    • Leave blank or select Not.
    • Select an activity, metric or information type from the second menu (for example, Activity, Density, Entity ID, etc.).
    • Select equals (=), less than (<) or greater than (>).
    • Depending on your selections so far, select an item from this menu or enter a specific value if required (for example, a density level).
  4. Click Add to verify the logic of your selections and to add them to the list of filters for that colour.

    If your criterion contains a logical error, a message is displayed beneath the list in red, for example. You must correct any errors for your criterion to be saved.

  5. Repeat step 3 to add more criteria to either the same colour or a new colour from your range.
  6. Click Apply to save your changes and OK to exit.
    Note: Please note that using colour schemes when playing back simulations can slow down performance.
