Detailed Description

We have a variable which changes at time interval.

For example, processor usage.

The Min property specifies start of the interval. The Max property specifies end of the interval. The Value property specifies the current time.

Since:

1.1.12.

Member Function Documentation

Add	(	[in] ULONG	Offset,
		[in] DOUBLE	Value
	)

Add value of the variable.

Parameters:

	Offset	Time for the value minus Min.
	Value	Value of the variable.

AddEx	(	[in] ULONG	Offset,
		[in] DOUBLE	Value,
		[in, defaultvalue("")] BSTR	Text
	)

Add value of the variable.

Parameters:

	Offset	Time for the value minus Min.
	Text	Comment.
	Value	Value of the variable.

BeginUpdate

(

)

Enables Update mode.

This method prevents updating of the control until the EndUpdate method is called.

Clear

(

)

Clear window, remove all values of the variable.

EndUpdate

(

)

Disables Update mode.

Property Documentation

VARIANT_BOOL RW AlwaysFillWindow

If Max - Min < Page then Page = Max - Min.

Default: TRUE.

VARIANT_BOOL RW Approximation

Enables calculation of values of the varable based on specified values.

Default: TRUE.

VARIANT_BOOL RW AutoRemove

If TRUE then values of the variable, which time is not in [Min,Max] interval will be removed automatically.

Default: TRUE.

IDispatch* RW BackgroundBrush

Brush object for the control's background.

DOUBLE RW MaxYValue

Maximum value for the variable.

DOUBLE RW MinYValue

Minimum value for the variable.

ULONG RW Page

Time interval size that window shows.

In milliseconds. If this less then Max - Min, then the user can use scroll bar to view different time.

ULONG RW PageControlWidth

Specifies what control width in pixels is equal to Page.

Default value if 0 that means Page is equal to the control width. If value > 0 then Page equals to the value and graph does not changes when the control width is changed.

LONG RW SelectedIndex

Selected index of the variable.

ULONG RW SelectedValue

Selected time minus Min.

In milliseconds.

DOUBLE R SelectedYValue

Selected value of the variable.
