This section describes how to define the general settings for a historic trend graph. The following is an example of the General page of the Historic Trend Graph property sheet.

The following table describes each property in the General page.

		Word		Description
Property		Description
ID		The object’s identifier. It is generated when the object is created and is unchangeable. The identifier is unique within the screen where the object is located. The format of the IDs for the historic trend graph is HTDnnnn.
Note		You can type a note for the object.
Shape settings		For details about the following properties, see Section 4.3.4 Setting up the Shape of an Object. , Border Color, BG Color.
Graph BG color		Select a color for the background of the graph.
Associated Data Logger		Specifies the associated data logger.
Data Source		Select data logger or file as the source of the collected data.
File Buffer ID		Specify the File Buffer ID if the data source is a file. To specify a file buffer ID for a file, you can use Load Logged Data From File operation of the function button. Please see Section 5.4 Performing Built-in Function Using Function Buttons for details.
Number of Curves		Specifies the number of curves. Max 16 curves are supported.
Direction	From Left to Right	Check this option to place the historic trend graph in horizontal direction.
Direction	From Top to Bottom	Check this option to place the historic trend graph in vertical direction.
Point Spacing	Time Based	Check this option if you want to draw the distance between two adjacent points based on time.
Point Spacing	Fixed Distance	The space between two adjacent data points on a trend curve can be a fixed distance in pixels rather than a distance determined by the time difference of the two points. Check this option if you want to draw the distance between two adjacent points in predefined pixels. You need to specify the distance from the dropdown list with 1,2,4,8,16 or 32 pixels. You can use the fixed distance to draw two adjacent points if the data logger is sampled not by time but by triggered.
Cursor	<Check box>	Check this option so the historic trend graph will display a cursor. You can touch and drag the cursor to the data point(s) that you want to select.
	Cursor Color	Select a color for the cursor.
	Value Display Font	Select a font for displaying the values of the selected data point(s).
	Date	Check this option to display the date at the top left of the historic trend graph object. You need to select a format for displaying the date. There are 17 formats available: dd/mm/yy, mm/dd/yy, yy/mm/dd, dd.mm.yy, mm.dd.yy, yy.mm.dd, dd-mm-yy, mm-dd-yy, yy-mm-dd, MMMdd, dd/mm, mm/dd, dd.mm, mm.dd, dd-mm, mm-dd, yyyy/mm/dd Note: dd: 01-31 (day); mm: 01-12 (month); yy: 00-99 (year); yyyy: 0000-9999(year); MMM: JAN-DEC (month)
	Time	Check this option if you want the object to display the Time at the top left corner. You need to select a format for displaying the time. There are 3 formats available: hh:mm, hh:mm:ss; mm:ss Note: hh: 00-23 (hour); mm: 00-50 (minute); ss: 00-59 (second);

Display Relative Time		Check this option if you want the object to display a relative measure of time.
Support Zoom		Check this option so the zoom option will be supported at runtime. You may use the function button to zoom in or zoom out of the historic trend graph at the runtime. This field is available only when the Dynamic Range field is not checked.
Dynamic Range	Dynamic Range	When this option is selected, the following three ranges can be specified at runtime: * The minimum and the maximum for the Y values of each curve * The maximum time duration for the X axis * The minimum and maximum of the marks for the Y axis The data that specifies the above three ranges should be set and arranged correctly in a memory block called the dynamic range parameter block. You need to specify the dynamic range parameter block in the Dynamic Range Parameter Block field.

Curves Show/Hide Controllable		When this option is selected, you can show or hide a curve by setting or resetting the corresponding bit of the Curves Show/Hide Control Word.
Curves Show/Hide Control Word.		Specifies the variable that shows or hides the curve when Curves Show/Hide Controllable is selected. Click to enter an address for this field. Click to select a tag for this field. To show #n curve, please set bit n-1 of the control word to 1.
Value Axis Scale Selectable		When this option is selected, you can change the value axis scale at runtime by setting Value Axis Scale Selection Word.
Value Axis Scale Selection Word		Specifies the variable that stores the value axis scale set when Value Axis Scale Selectable is selected. Click to enter an address for this field. Click to select a tag for this field. You can define up to 5 sets of scale settings for the value axis of a historic trend graph. This can be done on the Axis page of the configuration dialog box. The following is an example of the multiple scale settings.

		2N+1		Specify the position of the N-th point in the direction of the data value axis. (Note 1)
		Note 1: A valid value is between the specified Minimum and Maximum. When the value equals to the Minimum, it positions the associated reference line or the associated point of the reference polyline at the position corresponding to the minimum of the historic data. When the value equals to the Maximum, it positions the associated line or the point at the position corresponding to the maximum of the historic data. When the value is in between, the associated line or point is at a position in the graph area corresponding to the relation of the value among the Minimum and the Maximum. The following are examples with the specified minimum, maximum and control data:
		Minimum	Maximum		Control Data			Example
		-10		10	5
		0		100	30

					5	10	Value of the 2nd point
					6	65	Time of the 3rd point

					17	65	Value of the 8th point
	Maximal Number Of Points	The maximal number of points that the reference polyline can have.
	Minimum	When the value of the control data equals to the Minimum, it positions the reference lines or the points of the reference polyline at the position corresponds to the minimum of the historic data.
