ATTRIBUTE

Description

ASM_HLWIDTH

High/Low bar Width of riser in a stock chart

ASM_ITEM_DTXT

Item Data Text for data text items in a stock market chart

ASM_METRIC1/2/3

Define metric lines in a stock chart

ASM_OCHEIGHT

Open/Close Height of ticks in a stock chart

ASM_OCWIDTH

Open/Close Width of ticks in a stock chart

ASM_SHOW_CLOSE

Show/Hide close ticks in a stock chart

ASM_SHOW_OPEN

Show/Hide Open ticks in a stock

ASM_SYMBOL_STYLE

Defines the style of Markers on Stock Chart

This attribute sets the width of the HighLow bars (i.e., risers) in a stock market graph. It is similar to A2D_BAR_SPACING, but it allows the stock market bars to be any width desired.

Type:

INT16

Valid Range:

Any positive INT16 value

Default:

80

Example:

TDG_GraphPresetInfo GraphTable [4] = {
     {TDG_GRAPH_BARS ,8},
     {TDG_GRAPH_LINES,0},
     {TDG_GRAPH_AREA ,4},
     {TDG_GRAPH_SPECIAL, 5}};
INT16 nGraphType = 3; /* SELECT STOCK MARKET CHART */
INT16 two = 2;/* DATA FORMAT FOR HI/LO/OPEN VALUES */
INT16 HiLoWide = 2000;/* WIDTH OF HIGH/LOW RISER */
SetGraphAttrSL(gpGraph, NULL,
     A2D_DATAFORMAT, (void FAR *)&two);
SetGraphAttrSL(gpGraph, NULL,
     ASM_HLWIDTH, (void FAR *)&HiLoWide);
SetGraphAttr(gpGraph, GRAPH_LAYER,
     NULL_OBJECTID, NULL_SERIESID,
     NULL_GROUPID, A_GRAPH_PRESET,
      (void FAR *) &GraphTable[nGraphType]);

Notes:

Although there is no limit to the width of risers/bars in a stock market graph, reasonable/readable values are limited to the output device and the number of groups/items being charted. Larger values may cause risers to overlap.

When data text values are enabled via A2D_SHOW_DATATEXT, this attribute controls the type of data text items displayed in a stock market graph.

Type:

INT16

Valid Range:

0...3

0=

Show High Values

1=

Show Low Values

2=

Show Open Values

3=

Show Close Values

Default:

1 (Show Low Values)

Example:

TDG_GraphPresetInfo GraphTable [4] = {
     {TDG_GRAPH_BARS ,8},
     {TDG_GRAPH_LINES,0},
     {TDG_GRAPH_AREA ,4},
     {TDG_GRAPH_SPECIAL, 5}};
/* SELECT STOCK MARKET CHART */
INT16 nGraphType = 3;
/* DATA FORMAT FOR HI/LO/OPEN VALUES */
INT16 two = 2;
/* SHOW CLOSE VALUES */
INT16 StkValue = 3;
/* DOLLARS/CENTS ($0.00) FORMAT */
INT16 nDollarFmt = 8;
SetGraphAttrSL(gpGraph, NULL,
     A2D_DATAFORMAT, (void FAR *)&two);
SetGraphAttrSL(gpGraph, NULL,
     ASM_ITEM_DTXT, &StkValue);
SetGraphAttrSL(gpGraph, NULL,
     A2D_SHOW_DATATEXT, &bTRUE);
SetGraphAttrSL(gpGraph, NULL,
     A2D_FORMATDTXT_Y1,&nDollarFmt);
SetGraphAttr(gpGraph, GRAPH_LAYER,
     NULL_OBJECTID, NULL_SERIESID,
     NULL_GROUPID, A_GRAPH_PRESET,
      (void FAR *) &GraphTable[nGraphType]);

Notes:

The A2D_SHOW_DATATEXT attribute must be enabled (TRUE) in order for this attribute to have any affect on the graph. You may also use the A2D_FORMAT_DTXT_Y1 attribute to specify the format (i.e., typically dollars and cents ($9.99)) in which data text values are drawn.
