Drawing Scales

1. In the Draw menu or Draw toolbar, click Scale .
2. Move the cursor onto the screen where you want to draw a scale. A scale with default settings will display and move along with the cursor.
3. Click the desired position on the screen to place the scale. The upper-left corner of the bounding box of the scale will be at the clicked position.
4. Double-click the scale to bring up the Scale dialog box and then define the settings for the scale. The following is an example of the Scale dialog box. The corresponding scale is shown to the right of the dialog box.

The following table describes each property in the Scale dialog box.

Property		Description
Direction and Position		Select the direction and the position of the scale.
		Direction	Horizontal		Vertical
		Position	Top	Bottom	Left	Right
		Example
Dynamic Range	Dynamic Range	Check this item if you want the numbers of the scale ticks and the range of the scale marks to be dynamic, i.e. to be controlled by the specified variable.
	Parameter Block	Specifies the variable that controls the numbers of the scale ticks and the range of the scale marks. The variable is an array of four double-words (8 words). The following table describes the data members of the array.
		Word #	Data Type	Description
		0, 1	32-bit unsigned integer	The number of major ticks. The allowable range of this number is between 2 and 101.
		2, 3	32-bit unsigned integer	The number of divisions between two adjacent major ticks. The allowable range of this number is between 1 and 100.
		4, 5	32-bit signed integer	The minimum of the scale marks.
		6, 7	32-bit signed integer	The maximum of the scale marks.
		Example Assume a scale’s dynamic range control block is $U100. The following macro commands makes the scale look like this: $U100 = 3 (UD) // The number of major ticks. $U102 = 5 (UD) // The number of sub-divisions. $U104 = 0 (SD) // The minimum of the scale marks. $U106 = 100 (SD) // The maximum of the scale marks.
Color		The color of the scale. To specify the color, click the corresponding Color icon and select a color from the Color palette.
Number of Major Ticks		The number of major ticks. The minimum you can specify is two.
Number of Sub Divisions		The number of divisions between two adjacent major ticks. The minimum you can specify is one.
Minor Tick Length		The length of minor ticks.
Axis		Check this item if you want the scale to have an axis.
Marks	Marks	Check this option if you want the scale to have marks.
	Font	The font of the marks.
	Minimum	The minimum of the marks. It is a 32-bit integer.
	Maximum	The maximum of the marks. It is a 32-bit integer.
	Total Digits	The total digits to be displayed for the marks.
	Fractional Digits	The number of fractional digits for the marks. For example, when the Maximum is 5000, the Total Digits is 4, and the Fractional Digits is 2, the mark for the Maximum will be 50.00.
	Reverse Order	Check this option if you want the marks of the scale to show in reverse order. In normal order, the maximal mark is at the right end or top end of the scale. In reverse order, the maximal mark is at the left end or bottom end of the scale.
