.SH DESCRIPTION
|
|
The Cdk graph widget creates a graph widget. This widget can draw a graph in
|
|
both plot mode and line mode. The following are functions which create or
|
|
manipulate the Cdk graph box widget.
|
|
|
|
.SH AVAILABLE FUNCTIONS
|
|
CDKGRAPH *newCDKGraph (CDKSCREEN *\f2screen\f1, int \f2xpos\f1, int \f2ypos\f1, int \f2height\f1, int \f2width\f1, char *\f2title\f1, char *\f2xtitle\f1, char *\f2ytitle\f1);
|
|
.RS 3
|
|
This function creates a pointer to a graph widget. The \f2screen\f1 parameter
|
|
is the screen you wish this widget to be placed in. The parameter \f2xpos\f1
|
|
controls the placement of the object along the horizontal axis. This parameter
|
|
can accept an integer value or one of the pre-defined values of \f4LEFT\f1,
|
|
\f4RIGHT\f1, and \f4CENTER\f1. The parameter \f2ypos\f1 controls the placement
|
|
of the object along the vertical axis. This parameter can accept an integer
|
|
value or one of the pre-defined values of \f4TOP\f1, \f4BOTTOM\f1, and \f4CENTER\f1.
|
|
The parameters \f2height\f1 and \f2width\f1 control the height and width of the
|
|
widget. If you provide a value of zero for either of the height or the width,
|
|
the widget will be created with the full width and height of the screen. If
|
|
you provide a negative value, the widget will be created the full height or
|
|
width minus the value provided. The three parameters: \f2title\f1, \f2xtitle\f1,
|
|
and \f2ytitle\f1, are the graph title, the X axis title, and the Y axis title
|
|
respectively. The graph title can be more than one line; just provide a
|
|
carriage return character at the line break. If the widget could not be
|
|
created then a \f4NULL\f1 pointer is returned.

|
|
.RS 3
|
|
This function lets the programmer set the specific values of the graph widget.
|
|
The parameter \f2values\f1 is an integer array of the values to display in the
|
|
widget; \f2valueCount\f1 is the number of values in the array. The parameter
|
|
\f2graphCharacters\f1 is an array of the characters to use for each graph point.
|
|
The parameter \f2startAtZero\f1 states whether you want the graph to start at
|
|
zero or the lowest values of the X and Y axis'. The parameter \f2displayType\f1
|
|
accepts either \f4vPLOT\f1, to make the graph draw the values as a plot graph,
|
|
or \f4vLINE\f1 to draw the values as a line graph.

|

This function lets the programmer set the specific values of the graph widget.
|
|
The parameter \f2values\f1 is an integer array of the values to display in the
|
|
widget; where \f2valueCount\f1 is the number of values in the array. The
|

parameter \f2startAtZero\f1 states whether you want the graph to start at

zero or the lowest values of the X and Y axis'.

This function lets the programmer set a specific value of the graph widget.
|
|
The parameter \f2value\f1 is the new value, while \f2index\f1 is the

index where the new value will be stored. The parameter \f2startAtZero\f1
|
|
states whether you want the graph to start at zero or the lowest values of

the X and Y axis'.

The parameter \f2displayType\f1 accepts either \f4vPLOT\f1, to make the graph

graph.

This function moves the given widget to the given position. The parameters

\f2xpos\f1 and \f2ypos\f1 is the new position of the widget. The parameter
|
|
\f2xpos\f1 can accept an integer value or one of the pre-defined values of
|
|
\f4TOP\f1, \f4BOTTOM\f1, and \f4CENTER\f1. The parameter \f2ypos\f1 can
|
|
accept an integer value or one of the pre-defined values of \f4LEFT\f1,
|
|
\f4RIGHT\f1, and \f4CENTER\f1. The parameter \f2relative\f1 states whether
|
|
the \f2xpos\f1/\f2ypos\f1 pair is a relative move or an absolute move. For
|
|
example if \f2xpos\f1 = 1 and \f2ypos\f1 = 2 and \f2relative\f1 = \f2TRUE\f1,
|
|
then the widget would move one row down and two columns right. If the value
|
|
of \f2relative\f1 was \f2FALSE\f1 then the widget would move to the position
|
|
(1,2). Do not use the values of \f4TOP\f1, \f4BOTTOM\f1, \f4LEFT\f1,
|
|
\f4RIGHT\f1, or \f4CENTER\f1 when \f2relative\f1 = \f4TRUE\f1. (weird things
|
|
may happen). The final parameter \f2refresh\f1 is a boolean value which states
|
|
whether the widget will get refreshed after the move or not.
