Graph object

A graph is a representation of a series of data points (values). The graph can have a single series of values or multiple series.

Properties

Graph property	Datatype	Description
AccessibleDescription	String	A description of the control and/or its purpose for use by accessibility tools such as readers for visually impaired users.
AccessibleName	String	A label that briefly describes the control, such as the text in a button or the name of a menu item.
AccessibleRole	AccessibleRole (enumerated)	Describes what kind of user interface element the control is.
BackColor	Long	Specifies the numeric value of the background color: -2 to 16,777,215. For more information about color, see the section called “RGB” in PowerScript Reference.
Border	Boolean	Specifies whether the control has a border.
BorderStyle	BorderStyle (enumerated)	Specifies the style of the border of the control. Values are: StyleBox! StyleLowered! StyleRaised! StyleShadowBox!
BringToTop	Boolean	Specifies whether PowerBuilder moves the control to the top of the front-to-back order of the window or DataWindow control.
Category	grAxis	Specifies the properties of the category axis of the graph.
CategorySort	grSortType	Specifies how the categories are sorted.
ClassDefinition	PowerObject	An object of type PowerObject containing information about the class definition of the object or control.
Depth	Integer	Specifies the percent the depth is of the width of the graph.
DragAuto	Boolean	Specifies whether PowerBuilder puts the graph automatically into Drag mode. Values are: TRUE -- When the control is clicked, the control is automatically in Drag mode. FALSE -- When the control is clicked, the control is not automatically in Drag mode. You have to manually put the control into Drag mode by using the Drag function.
DragIcon	String	Specifies the name of the stock icon or the file containing the icon you want to display when the user drags a control (the ICO file). The default icon is a box the size of the control. When the user drags a control, the icon displays when the control is over an area in which the control can be dropped (a valid drop area). When the control is over an area that is not a valid drop area, the No-Drop icon displays.
Elevation	Integer	Specifies the angle of front-to-back elevation.
Enabled	Boolean	Specifies whether the control is enabled (can be selected). Values are: TRUE -- Control can be selected. FALSE -- Control cannot be selected.
FocusRectangle	Boolean	Specifies whether a dotted rectangle (the focus rectangle) frames the control when it has focus. Values are: TRUE -- Control will be framed when it has focus. FALSE -- Control will not be framed when it has focus.
GraphType	grGraphType (enumerated)	Specifies the type of the graph. Values are: Area3D! AreaGraph! Bar3DGraph! Bar3DObjGraph! BarGraph! BarStack3DObjGraph! BarStackGraph! Col3DGraph! Col3DObjGraph! ColGraph! ColStack3DObjGraph! ColStackGraph! Line3D! LineGraph! Pie3D! PieGraph! ScatterGraph!
Height	Integer	Specifies the height of the control, in PowerBuilder units.
Legend	grLegendType (enumerated)	Specifies the alignment of the text in the graph legend. Values are: AtBottom! AtLeft! AtRight! AtTop! NoLegend!
LegendDispAttr	grDispAttr	Specifies the type style for the text in the graph legend, including the text style, size, color, and rotation.
OverlapPercent	Integer	Specifies the percent of the width of the data markers by which different series in a graph overlap.
Perspective	Integer	Specifies the distance the graph is from the front of the window.
PieDispAttr	grDispAttr	Specifies properties of the text in pie graph labels, including the text style, size, color, and rotation.
Pointer	String	Contains the name of the stock pointer or the file containing the pointer used for the graph.
Render3D	Boolean	Indicates whether the 3D graph is rendered in the DirectX style.
Rotation	Integer	Specifies how much to rotate the graph from left to right.
Series	grAxis	Specifies the series in the graph.
SeriesSort	grSortType	Specifies how the series are sorted.
ShadeColor	Long	Specifies the color used for the shading in the graph.
Spacing	Integer	Specifies the space between data markers in the graph as a percent.
TabOrder	Integer	Specifies the tab value of the control in the tabbing sequence (0 means the user cannot tab to the control).
Tag	String	Specifies the tag value of the control.
TextColor	Long	Specifies the color to be used for the text in the control.
Title	String	Specifies the text of the title for the graph.
TitleDispAttr	grDispAttr	Specifies the type style for the text in the graph title, including the text style, size, color, and rotation.
Values	grAxis	Specifies the values of the value axis of the graph.
Visible	Boolean	Specifies whether the control is visible. Values are: TRUE -- Control is visible. FALSE -- Control is not visible.
Width	Integer	Specifies the stroke weight of text in the control; for example, 400 for normal or 700 for bold.
X	Integer	Specifies the X position (the distance from the left edge of the parent window), in PowerBuilder units.
Y	Integer	Specifies the Y position (the distance from the top of the parent window), in PowerBuilder units.

Events

Graph event	Occurs
Clicked	When the control is clicked (selected or unselected)
Constructor	Immediately before the Open event occurs in the window
Destructor	Immediately after the Close event occurs in the window
DoubleClicked	When the control is double-clicked (selected or unselected)
DragDrop	When a dragged control is dropped on the control
DragEnter	When a dragged control enters the control
DragLeave	When dragged control leaves the control
DragWithin	When a dragged control is within the control
GetFocus	Just before the control receives focus (before it is selected and becomes active)
Help	When the user presses the F1 key or drags the context help button (question mark) from the title bar to a menu item or control
LoseFocus	When the control loses focus (becomes inactive)
Other	When a Windows message occurs that is not a PowerBuilder event
RButtonDown	When the right mouse button is pressed on the control
