The Cdk graph widget creates a graph in either X/Y plot or line
mode. The following functions create or manipulate the Cdk graph box
widget.
- activateCDKGraph
- this is an obsolete function that calls drawCDKGraph.
- destroyCDKGraph
- removes the widget from the screen and frees memory the object used.
- drawCDKGraph
- draws the graph widget on the screen. The box option tells whether
to draw the widget with a box.
- eraseCDKGraph
- removes the widget from the screen. This does NOT destroy the
widget.
- getCDKGraphBox
- returns true if the widget will be drawn with a box around it.
- getCDKGraphCharacter
- returns the character in the graph at the given index.
- getCDKGraphCharacters
- returns all the characters currently in the graph widget.
- getCDKGraphDisplayType
- returns the current display type of the widget.
- getCDKGraphValue
- returns the value in the graph at the given index.
- getCDKGraphValues
- returns all the values currently in the graph widget.
- moveCDKGraph
- moves the given widget to the given position.
- The parameters xpos and ypos are the new position of the
widget. The parameter xpos may be an integer or one of the
pre-defined values TOP, BOTTOM, and CENTER. The
parameter ypos may be an integer or one of the pre-defined values
LEFT, RIGHT, and CENTER.
- The parameter relative states whether the xpos/ypos
pair is a relative move or an absolute move.
- For example, if xpos = 1 and ypos = 2 and relative =
TRUE, then the widget would move one row down and two columns
right. If the value of relative was FALSE then the widget
would move to the position (1,2). Do not use the values TOP,
BOTTOM, LEFT, RIGHT, or CENTER when
relative = TRUE. (weird things may happen).
- •
- The final parameter refresh is a boolean value which states whether
the widget will get refreshed after the move.
- newCDKGraph
- creates a pointer to a graph widget. Parameters:
- screen
- is the screen you wish this widget to be placed in.
- xpos
- controls the placement of the object along the horizontal axis. It may be
an integer or one of the pre-defined values LEFT, RIGHT, and
CENTER.
- ypos
- controls the placement of the object along the vertical axis. It may be an
integer or one of the pre-defined values TOP, BOTTOM, and
CENTER.
- height and
- width
- control the height and width of the widget. If you provide a 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.
- title,
- xtitle and
- ytitle
- are the graph title, the X axis title, and the Y axis title respectively.
The graph title may be more than one line by providing a carriage return
character at the line break.
- If the widget could not be created then a NULL pointer is
returned.
- positionCDKGraph
- allows the user to move the widget around the screen via the cursor/keypad
keys. See cdk_position (3) for key bindings.
- setCDKGraph
- lets the programmer set the specific values of the graph widget.
- The parameter values is an integer array of the values to display
in the widget; valueCount is the number of values in the
array.
- The parameter graphCharacters is an array of the characters to use
for each graph point.
- The parameter startAtZero states whether you want the graph to
start at zero or the lowest values of the X and Y axis'.
- The parameter displayType may be vPLOT, to make the graph
draw the values as a plot graph, or vLINE to draw the values as a
line graph.
- setCDKGraphBackgroundAttrib
- sets the background attribute of the widget. The parameter
attribute is a curses attribute, e.g., A_BOLD.
- setCDKGraphBackgroundColor
- sets the background color of the widget. The parameter color is in
the format of the Cdk format strings. See cdk_display (3).
- setCDKGraphBox
- sets whether the widget will be drawn with a box around it.
- setCDKGraphBoxAttribute
- function sets the attribute of the box.
- setCDKGraphCharacter
- lets the programmer set a specific character of the graph widget. The
parameter character is the new character, while index is the
index where the new character will be stored.
- setCDKGraphCharacters
- lets the programmer set the specific characters of the graph widget. The
parameter characters is a char pointer array of the characters to
display in the widget.
- setCDKGraphDisplayType
- allows the programmer tochange the way the graph draws itself. The
parameter displayType may be vPLOT, to make the graph draw
the values as a plot graph, or vLINE to draw the values as a line
graph.
- setCDKGraphHorizontalChar
- sets the horizontal drawing character for the box to the given
character.
- setCDKGraphLLChar
- sets the lower left hand corner of the widget's box to the given
character.
- setCDKGraphLRChar
- sets the lower right hand corner of the widget's box to the given
character.
- setCDKGraphULChar
- sets the upper left hand corner of the widget's box to the given
character.
- setCDKGraphURChar
- sets the upper right hand corner of the widget's box to the given
character.
- setCDKGraphValue
- lets the programmer set a specific value of the graph widget.
- The parameter value is the new value, while index is the
index where the new value will be stored.
- The parameter startAtZero states whether you want the graph to
start at zero or the lowest values of the X and Y axis.
- setCDKGraphValues
- lets the programmer set the specific values of the graph widget.
- The parameter values is an integer array of the values to display
in the widget.
- valueCount is the number of values in the array.
- The parameter startAtZero states whether you want the graph to
start at zero or the lowest values of the X and Y axis'.
- setCDKGraphVerticalChar
- sets the vertical drawing character for the box to the given
character.
