Scale Properties

The properties on this tab .- specify the look and position of the scale(s) on the selected gauge. Note that you can have more than one scale on a gauge - useful if you wish to present several information sets using separate pointers for each.

If you have more than one gauge in the container, then use the Gauge List to select the gauge you wish to work with (in the figure, Gauge1 is selected). If the gauge you wish to work with has more than one scale, select the scale you wish to set up/change using the Scale List (in the figure, Scale1 is selected).

Click the tabs and properties in the figure for further details.

Figure 1 - The Scales > Scale properties

The properties on this tab are as follows:

• Scale List - a gauge can have several scales. As you create scales they are added to this list. Click the down-arrow beside the field and select the scale you wish to work with. Any changes you make to any of the scale properties will be applied only to the selected scale.
• Add - click to add another scale to the gauge style. The scales are numbered sequentially, and are listed in the Scale List field.
• Delete - select a scale in the Scale list field and click Delete to delete the selected scale.

Scale:

• Minimum - specifies the minimum value of the scale.
• Maximum - specifies the maximum value of the scale.
• Reversed - the scale will run as default in the clock-wise direction. check this box to have the scale run anti-clockwise.
• Logarithmic - check this box to use a logarithmic scale.

Position:

• Pivot Point X - specifies the X (horizontal) position of the center of rotation of the pointer. The value is specified as a percent of the gauge's width, from the left edge.
• Pivot Point Y - specifies the Y (vertical) position of the center of rotation of the pointer. The value is specified as a percent of the gauge's height, from the upper edge.
• Start Angle - the angle, in degrees, in the clock-wise direction from the lowest point of the gauge, at which the scale is to start.
• Sweep Angle - the total angle, in degrees, around which the scale is to extend.
• Radius - the radius of the scale from the pivot point (of the needle) to the center-line of the scale. The value is specified as a percentage of the diameter of the gauge measured to the outside edge of the gauge frame. If the gauge frame is rectangular, then the value is specified as a percentage of the shortest (width or height) dimension.

Label and Major Ticks Interval:

• Automatic - select to create the labels and the major tick marks automatically at every tenth position.
• Custom - select to activate the manual input for the labels and the major tick marks positions. Type a value N into the field to place the labels and major tick marks at every Nth position.

Appearance:

• Width - the total thickness, including the borders, of the scale bar.
• Fill color - the color of the "internal" area of the scale bar.
• Shadow - adds a shadow effect to the scale, of the specified width. The shadow is created below and to the right of the scale.
• Border Color - the color of the scale's border line.

Labels

The properties on this tab specify the position, look and feel of the scale labels (the numbers indicating the data values) .

If you have more than one gauge in the container, then use the Gauge List to select the gauge you wish to work with. If the gauge you wish to work with has more than one scale, select the scale you wish to set up/change using the Scale List.

Click on the tabs and properties in the figure for further details.

Figure 2 - The Scales > Labels properties

The Properties are as follows:

Labels Position:

• Inside - select this option if you want the labels to be displayed inside the scale.
• Outside - select this option if you want the labels to be displayed outside the scale.
• Cross- select this option if you want the labels to be displayed within the area of the scale line.
• Labels Offset - once you have selected the label placement, you can apply an offset to fine-tune the position. Specify a value in pixels.

Labels Text Format:

• Format - specifies the number format to be used for the labels.
• Decimals - specify the number of decimal places you wish to have after the label integer.

Label Fonts and Color:

• Font - this is the font type to be used for the applicable text item, for example Arial, Courier, Times etc. Type the desired font type into the field and apply/save the changes.
• Font Size - this property defines the size of the characters to be used.
• Angle - if you want the labels to be presented at a specific angle, type the angle in here.
• Color - the Color property specifies the color to be used for the text.

• Show End Labels - if you do not wish to display the first and last labels on the scale, uncheck this box.
• Rotate Circular Scale Labels - check this box if you wish the labels to rotate to follow the curvature of the scale.
• Allow Upside Down Labels - check this box if you wish to allow the labels to be displayed inverted if "required" to follow the curvature of the scale.

Major/Minor Ticks

The properties on these tabs enable you to specify the look and feel of the major and minor tick marks. Note that the properties for the two tick mark types are identical, so they are described only once.

If you have more than one gauge in the container, then use the Gauge List to select the gauge you wish to work with. If the gauge you wish to work with has more than one scale, select the scale you wish to set up/change using the Scale List.

Figure 3 - The Scales > Tick Marks properties

The properties are as follows:

• Tick Marks Visible - this box is checked by default. Uncheck the box if you do not wish to see the tick marks.

Tick Marks:

• Shape - select the shape of the tick marks.
• Placement - select where relative to the scale the tick marks are to be positioned.
• Length - specifies the length of the tick marks, in pixels.
• Width - specifies the width of the tick marks, in pixels.
• Scale Offset - if you wish to offset the tick marks in the scale (move them around the scale by a specified amount) type the distance in here.

Tick Marks Appearance:

• Fill Color - specifies the color used to present the tick marks.
• Use Gradient Fill - check this box if you wish to use a gradient fill for the tick marks.
• Border Color - specifies the color used to present the tick mark's border line.
• Border Width - if this is set to a value greater than 1 then the border line will be displayed, using the color specified in Border Color.
