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 wid- get. AVAILABLE FUNCTIONS
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 wid- get 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 cre- ated 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 charac- ters 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; where 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.
