It provides a single, reasonably consistent # interface for creating HTML based graphs. The idea behind # this code is that the user of the class sets up four or five # arrays and pass these to html_graph() which then takes # care of all the messy HTML layout. I am reasonably happy # with the outcome of this interface. The HTML that must be # generated for HTML graphs *is* messy, and the interface is # very clean and flexible. I think that once you generate # one graph with it, you'll never look at creating HTML graphs # the same. The arrays that must be set up consist of: # # * A names array containing column/row identifiers ($names) # * One or two values arrays containg corresponding # values to the column/row names ($values & $dvalues) # * One or two bars array which also corresponds to the names # array. The values in these arrays are URLS to graphics # or color codes starting with a # which will be used to # generate the graph bar. Color codes and graphics may # be mixed in the same chart, although color codes can't # be used on Vertical charts. ($bars & $dbars) # * The heart of customization... a vals array. If this # array isn't created then html_graphs will use all # default values for the chart. Items that are customizable # include font styles & colors, backgrounds, graphics, # labels, cellspacing, cellpadding, borders, anotations # and scaling factor. ($vals) # ####################################################################### # # Known Bugs: # # * Currently the $vals["background"] tag element doesn't # work in Netscape. # ####################################################################### # # To Do: # # * Would like to make the $vals array to html_graph() completely # optional. Currently it has to at least be an empty array. # ####################################################################### # # Contributors: # # Jan Diepens - Eindhoven University of Technologie # Jean-Pierre Arneodo # ####################################################################### # # Contact: # # If you have questions, suggestions, bugs, bug fixes, or enhancements # please send them to pdavis@pobox.com so that they may be wrapped into # future versions of HTML_Graph. # ####################################################################### # # Examples: # # See http://www.pobox.com/~pdavis/programs/ # ####################################################################### */ /* ####################################################################### # # Function: html_graph($names, $values, $bars, $vals[, $dvalues, $dbars]) # # Purpose: Calls routines to initialize defaults, set up table # print data, and close table. # # Arguments: # $names - Array of element names. # $values - Array of corresponding values for elements. # $bars - Array of corresponding graphic image names # or color codes (begining with a #) for elements. # Color codes can't be used on vertical charts. # $dvalues - Array of corresponding values for elements. # This set is required only in the double graph. # $dbars - Array of corresponding graphic image names # or color codes (begining with a #) for elements. # This set is required only in the double graph. # # $vals - array("vlabel"=>"", # "hlabel"=>"", # "type"=>"", # "cellpadding"=>"", # "cellspacing"=>"", # "border"=>"", # "width"=>"", # "background"=>"", # "vfcolor"=>"", # "hfcolor"=>"", # "vbgcolor"=>"", # "hbgcolor"=>"", # "vfstyle"=>"", # "hfstyle"=>"", # "noshowvals"=>"", # "scale"=>"", # "namebgcolor"=>"", # "valuebgcolor"=>"", # "namefcolor"=>"", # "valuefcolor"=>"", # "namefstyle"=>"", # "valuefstyle"=>"", # "doublefcolor"=>"") # # Where: # # vlabel - Vertical Label to apply # default is NUL # hlabel - Horizontal Label to apply # default is NUL # type - Type of graph # 0 = horizontal # 1 = vertical # 2 = double horizontal # 3 = double vertical # default is 0 # cellpadding - Padding for the overall table # default is 0 # cellspacing - Space for the overall table # default is 0 # border - Border size for the overall table # default is 0 # width - Width of the overall table # default is NUL # background - Background image for the overall table # If this value exists then no BGCOLOR # codes will be added to table elements. # default is NUL # vfcolor - Vertical label font color # default is #000000 # hfcolor - Horizontal label font color # default is #000000 # vbgcolor - Vertical label background color # Not used if background is set # default is #FFFFFF # hbgcolor - Horizontal label background color # Not used if background is set # default is #FFFFFF # vfstyle - Vertical label font style # default is NUL # hfstyle - Horizontal label font style # default is NUL # noshowvals - Don't show numeric value at end of graphic # Boolean value, default is FALSE # scale - Scale values by some number. # default is 1. # namebgcolor - Color code for element name cells # Not used if background is set # default is "#000000" # valuebgcolor - Color code for value cells # Not used if background is set # default is "#000000" # namefcolor - Color code for font of name element # default is "#FFFFFF" # valuefcolor - Color code for font of value element # default is "#000000" # namefstyle - Style code for font of name element # default is NUL # valuefstyle - Style code for font of value element # default is NUL # doublefcolor - Color code for font of second element value # default is "#886666" # ####################################################################### */ function html_graph($names, $values, $bars, $vals, $dvalues=0, $dbars=0) { // Set the error level on entry and exit so as not to interfear // with anyone elses error checking. $er = error_reporting(1); // Set the values that the user didn't $vals = hv_graph_defaults($vals); start_graph($vals, $names); if ($vals[ "type"] == 0) { horizontal_graph($names, $values, $bars, $vals); } elseif ($vals[ "type"] == 1) { vertical_graph($names, $values, $bars, $vals); } elseif ($vals[ "type"] == 2) { double_horizontal_graph($names, $values, $bars, $vals, $dvalues, $dbars); } elseif ($vals[ "type"] == 3) { double_vertical_graph($names, $values, $bars, $vals, $dvalues, $dbars); } end_graph(); // Set the error level back to where it was. error_reporting($er); } /* ####################################################################### # # Function: html_graph_init() # # Purpose: Sets up the $vals array by initializing all values to # null.
