Display

Use the parameters on the Display tab to set display options for strings, markers along strings, and polygons (closed strings).

Note that some display properties may be viewed and edited in the Vizex Property Window:

Line Style

Line sets give you the ability to apply different line styles and line widths to the polylines in a single dataset. You can apply them in the same way that you can apply colours, hatches and symbols to your data.

Line field

Double-click (F3) to select the name of a field that will be matched to the code values in a Line set.

Line set

If you have specified a Line field, double click (F3) to select the set that will be used to control the style and the width of the polylines in the dataset.

Line type

Select a line type. A preview of each line type is shown in the drop-down list. A variety of solid, dotted, and dashed line styles are available for selection.

Note: Extended line styles such as double lines are not compatible with 2D plots (they will render as a solid line) and will only display properly in Vizex and 3D Vizex plots (and screenshots). Extended line styles are displayed in blue in the Line Type drop down.

Line width

Select a (THIN, MEDIUM, THICK, or custom) line width from the drop-down list. An extensive selection of custom widths (in millimetres) are available for selection.

Colour Coding

When strings or points are added to a new layer, a Colour field is added to the Data Properties and is auto-populated with a default colour (initially NULL) that can be quickly changed alongside other properties in the Vizex Property Pane.

Colour field

Specify the name of a field which contains the values that will be used to colour-code the display. If you are mapping Colour field values to a Colour Set, the values in the Colour field must be valid RGB, HTML Hex, Hex, or Integer colour definitions.

Format	Example
RGB	89,169,215	RGB ordered
HTML Hex	#59A9D7	BGR ordered
Hex	0x59a9d7	BGR ordered
Int	5876183	BGR ordered: RED + (GREEN*256) + (BLUE*65536)

You can choose to select colour values directly from the Colour field without selecting a Colour set. In this case, you can also select a formatted Colour field.

You can view and edit the RGB values assigned to the Colour field in the Property Window. Click on the ellipsis to open the Colour picker:

Colour set

To map values in the Colour field to the colour values in a Colour set, double click (F3) to select the set that will be used to control the display colour. Right-click (F4) to create or edit a Colour set.

Default colour

Double-click (F3) to select the colour that will be used when a Colour field or a Colour set is not defined - or when a value in the Colour field is either not valid or is not mapped in the Colour set.

Fill Polygons

Select this option if you want to apply a hatching or transparency to the closed polygons in the display.

Hatch field

Double click (F3) or click on the List icon to select the name of a field containing the data that will control the hatching. The hatch set associated with this field maps hatch patterns to text strings or numeric ranges. For each record in the file, the hatch pattern to be used is determined by the value in this field.

Hatch set

Double click (F3) to select the set that will be used to control the hatch pattern. The hatch set maps hatch patterns to text strings or numeric ranges. This determines the hatch pattern for each value in the Hatch field. Right click (F4) to create or edit a hatch set.

Hatch

Double click (F3) to select the hatch that will be used when a hatch set is not defined, or when the value in the hatch field is not mapped in the hatch set.

The default Hatch setting is Solid with a colour of pastel blue - as displayed in the image above.

Hatch Pattern Orientation

Double click (F3) or click on the List icon to select the name of a Rotation field containing rotation values (clockwise, in degrees) that will be used to rotate the hatch pattern.

Default rotation

You can also define a default rotation for the hatch. This will be used when a Rotation field is not defined, or when rotation values in the Rotation field are missing or invalid.

Transparency

Use the transparency slider to specify the intensity of the polygons. The visibility of the layers underneath the polygons will be determined by the degree of transparency you select.
