API_TILT

Tilt a pie chart

API_TILT_ON

Tilt On/Off

This attribute enables/disables autofitting of the group label in the box defined by API_INSET_LBLPIE. If autofitting is disabled, the font size currently defined for group labels is used to draw the label.

Type:

BOOLEAN16

Valid Range:

TRUE/FALSE

TRUE=

Group label text is autofitted in the box

FALSE=

No autofitting

Default:

TRUE

Example:

/* Disable group label autofit */
BOOLEAN bPieAutofitGroup = FALSE;
SetGraphAttr (pGraph, GRAPH_LAYER,
     NULL_OBJECTID,NULL_SERIESID,NULL_GROUPID,
     API_AUTOFIT_LBLPIE ,
      (void FAR *) &bPieAutofitGroup);

Notes:

If API_AUTOFIT_LBLPIE is disabled, A_FONTSIZE_VC could be used to modify the size of the group label font. It is recommended that your application not modify the font size in this manner because the detection box for the label would not be the same size as the label itself. It is recommended that you use API_INSET_LBLPIE to change the size of the group label box to indirectly change the size of the font.

Pie

This attribute controls the apparent depth of the pie, that is, thickness of the crust. A value of zero is used to create a pie with no crust, 2-D. A value of 300 creates a crust thickness equal to the height of the frame.

Type:

INT16

Valid Range:

0...300

Default:

15

Example:

INT16 nPieDepth = 75;
SetGraphAttr (pGraph, GRAPH_LAYER,
     NULL_OBJECTID,NULL_SERIESID,NULL_GROUPID,
     API_DEPTH,(void FAR *)&nPieDepth);

Notes:

1.

Aesthetically good values range from 10 to 50. Greater than 50 and the pie begins to look disproportionate.

2.

The value is the number of virtual coordinates divided by 10. For example, a setting of 30 is equivalent to 300 virtual pixels.

TRUE=

Slices are drawn clockwise (CW) from the starting angle. The example assumes starting angle of 90 degrees

FALSE=

Slices are drawn counter clockwise (CCW) from the starting angle. The example assumes a starting angle of 90 degrees.

Default:

TRUE

Example:

/* Set to Counter Clockwise */
BOOLEAN bPieDrawDirection = FALSE;
SetGraphAttr (pGraph, GRAPH_LAYER,
     NULL_OBJECTID,NULL_SERIESID,NULL_GROUPID,
     API_DRAW_CLOCKWISE ,

Pie

This attribute defines the margins around the area for the group title. The BoxInstRec defines the margins on the four sides around the group title label. The margins are defined as a percentage of the width/height of the frame. For example, to create a group label whose width is 20% of the frame width, centered horizontally, set 40% left and right margin.

Type:

typedef struct {
     INT xULC;
     INT yULC;
     INT xLRC;
     INT yLRC;
} BoxInstRec;

Valid Range:

xULC: Left margin. % of frame width from left of frame to start of group label.

yULC: Top margin. % of frame height from top of frame to top of group label.

xLRC: Right margin. % of frame width from right of frame to right side of group label.

yLRC: Bottom margin. % of frame height from bottom of frame to bottom of group label.

Default:

xULC = 35, xLRC = 35, yULC = 80, yLRC = 10

Example:

BoxInstRec bxGroup;
bxGroup.xULC = 40; /* 40% left margin */
bxGroup.xLRC = 40; /* 40% right margin */
bxGroup.yULC = 90; /* 90% top margin */
/* 0% puts group label at bottom of frame */

Pie

This attribute defines the margins around a pie. The margins are defined as a percentage of the width/height of the frame. For example, to create a pie whose width is 80% of the frame width, centered horizontally would be 10% left margin and 10% right margin.

Type:

typedef struct {
     INT xULC;
     INT yULC;
     INT xLRC;
     INT yLRC;
} BoxInstRec;

Valid Range:

xULC: Left margin.% of frame width from left of frame to start of pie.

yULC: Top margin.% of frame height from top of frame to top of pie.

xLRC: Right margin.% of frame width from right of frame to right side of pie.

yLRC: Bottom margin.% of frame height from bottom of frame to bottom of pie.

Default:

xULC = 20, xLRC = 20, yULC = 20, yLRC = 20

Notes:

1.

For a single pie chart, the amount of space available is the entire frame. For a multiple pie chart the amount of space available is the portion of the frame allocated for each pie.

2.

The margins set by API_INSET_PIE are applied to each pie in a multiple pie chart.

     NULL_OBJECTID,NULL_SERIESID,NULL_GROUPID,
     API_PIESPERROW,(void FAR *) &nPiesPerRow);

Pie

This attribute is used to rotate a pie. A pie with zero degrees rotation begins drawing slices at the 3 o'clock position. The rotation angle causes the pie to rotate counter clockwise (CCW). Applying a 90 degree rotation causes the slices to begin drawing at the 12 o'clock position.

Type:

INT16

Valid Range:

0...359.

0=

No rotation. First slice begins at 3 o'clock position

90 =

The pie rotates counter clockwise 90 degrees. The starting angle to draw the first slice of the pie is at 12 o'clock position.

359 =

The pie rotates counter clockwise 359 degrees.

Default:

Zero

Example:

INT16 nPieRotation = 90;
SetGraphAttr (pGraph, GRAPH_LAYER,
     NULL_OBJECTID,NULL_SERIESID,NULL_GROUPID,
     API_ROTATE,(void FAR *) &nPieRotation);

This attributes deletes or restores a pie slice. A deleted slice is not drawn on the chart, the space the slice would have occupied is empty.

Type:

     BOOLEAN bValue;
} TDG_SerDepBOOLEAN16, FAR * TDG_SerDepBOOLEAN16Ptr;

Valid Range:

nSeriesID: seriesID number of slice to apply attribute

bValue: TRUE / FALSE

TRUE=

Delete a slice. (The slice is not drawn)

FALSE=

Undelete a slice. If a slice is not deleted this has no impact.

Default:

FALSE

Example:

TDG_SerDepBOOLEAN16 noslice;
/* Delete first slice */
noslice.nSeriesID = 0;
noslice.bValue = TRUE;
SetGraphAttr (pGraph, GRAPH_LAYER,
     NULL_OBJECTID,NULL_SERIESID,NULL_GROUPID,

/* to restore a slice */
noslice.bValue = FALSE;
/* to restore all slices */
noslice.nSeriesID = SERCON_DOALL;
noslice.bValue = FALSE;

Notes:

1.

A detnode is not created for a deleted slice.

2.

API_SLICE_RESTORE can be used to restore all deleted slices. However, it also reattaches any previously detached slices, API_SLICE_DELETE does not move a slice when it is undeleted.

3.

Use SERCON_DOALL to delete/restore all of the slices. Use SERCON_USESELLIST to delete all the slices in a selection list.

Pie

This attribute can be used to detach a pie slice from the pie. The amount of detachment is a percentage of the distance from the center of the pie to the edge of the pie. 100% would cause the center point of the slice to image at the edge of the pie.

Type:

typedef struct _TDG_SerDepINT16 {
     INT16 nSeriesID;
     INT16 nValue;
} TDG_SerDepINT16, FAR * TDG_SerDepINT16Ptr;

Valid Range:

nSeriesID: seriesID number of slice to move

nValue: 0...100

Default:

Zero

Example:

TDG_SerDepINT16 serveslice;
/* Detach first slice */
serveslice.nSeriesID = 0;
/* 10% detachment */
serveslice.nValue = 10;
SetGraphAttr(pGraph, GRAPH_LAYER,
     NULL_OBJECTID,NULL_SERIESID,NULL_GROUPID,
     API_SLICE_MOVE,
      (void FAR *)&serveslice);
/* to detach all the slices the same amount */
serveslice.nSeriesID = SERCON_DOALL;

Notes:

1.

Detaching the slice too much may cause the slice to image outside the chart frame.

2.

Use SERCON_DOALL to detach all of the slices the same amount. Use SERCON_USESELLIST to detach all the slices in a selection list.

Pie

This attribute defines the amount of tilt applied to the pie. A pie with zero degrees tilt is drawn as a regular 2-D pie. As tilt is applied, the pie is rotated backward on the x-axis. The tilting creates a 3-D effect, especially when used in conjunction with API_DEPTH. Tilting must be enabled using the API_TILT_ON attribute.

Type:

INT16

Valid Range:

0...89. 0 = No tilt. Pie is drawn as a 2-D pie.

Default:

40

Notes:

1.

The attribute API_TILT_ON must be enabled to display the tilt.

2.

When a pie is tilted, it's apparent height is reduced to create the tilt effect. By increasing the crust thickness, the size of the pie can be increased to better fill the space between the pie and the frame. The crust thickness is controlled by the attribute API_DEPTH.

Pie

Enables pie tilting to create a 3-D effect. The amount of pie tilt is defined by API_TILT.

Type:

BOOLEAN16

Valid Range:

TRUE / FALSE

TRUE=

Tilt is enabled

FALSE=

No tilt. Pie is drawn as a 2-D pie

Default:

TRUE

Example:

/* DISABLE PIE TILT */
BOOLEAN bPieTilt = FALSE;
SetGraphAttr (pGraph, GRAPH_LAYER,
     NULL_OBJECTID,NULL_SERIESID,NULL_GROUPID,
     API_TILT_ON, (void FAR *)&bPieTilt);

Notes:

Setting API_TILT to 0 has the same effect as disabling pie tilt with this attribute
