NAME
       PSGRAPH - Perl extension for batch creation of charts and graphs

SYNOPSIS
         use PSGRAPH;
         my $psgraph = PSGRAPH->new();

         #for pie charts, setInitialdegree sets the starting point for data. The default is 120.
         $psgraph->setInitialdegree(integer);

         #label and color files must be tab delimited with a string for the label and CMYK color numbers
         #example: Salary      .23     .46     .73     0
         #for pie5 (exploded pie) include the string for the label, CMYK number and integer for the exploded section
         #example: Salary      .23     .46     .73     0       1
         #There must be a line for each data element for each record
         $psgraph->setLabelandColor(’your label and color file’);

         #data files must be tab delimited populated with the value for each data element
         #pie slice, bar, column, etc)
         #the last element in each row is the identifying index (employee number, SSN or any unique string) No spaces.
         $psgraph->setData(’your data file’);

         #must be one of the supported graphic types
         #as of May 2014 the supported types are 2Dpie, 2Dcolumn and 2Dbar
         $psgraph->setGraphic(’type of graphic’);

         #set the subtype (or take the default)
         #Valid subtypes currently are, for 2Dpie:
           #1 pie with callout lines with labels at the end of the lines (default)
           #2 pie with callout lines with percentages and labels at the end of the lines
              The percentages are calculated by the program
           #3 pie with legend
           #4 pie with percentages and legend
           #5 exploded pie
         #Valid subtypes currently are, for 2Dcolumn:
           #1 (default)
         #Valid subtypes currently are, for 2Dbar:
           #1 (default)
         $psgraph->setSubtype(subtype);

         #set the legend position for graphics with legends (or take the default)
         #valid positions are right (default), bottom and left
         $psgraph->setLegendpos(’position’);

         #set the scale of the graphic
         #all graphics are initially written in Postcript, so they may be scaled to any size without loss of detail.
         #type is not distorted when the graphic is, as in an oval shaped pie
         #the basic size of the graphics are:
           #Pie: 412 points (5.72")
           #Bar: The height is dependent on the number of bars in the data, calculated by:
               #24 + bar height (set by setColumnwidth) * 1.5 + .5 * bar height. The width is 401 points (5.57").
           #Column: The height is 220.75 points (3.07") The width is dependent on the number of columns in the data, calculated by:
                       #72 + column width * number of columns * 1.5 + .5 * column width
         #Horizontal Scale (1 is 100% of the base size):
         $psgraph->setHscale(horizontal scale)
         #Vertical Scale (1 is 100% of the base size):
         $psgraph->setVscale(vertical scale)
         #Set the explode offset in points (default is 12)
         $psgraph->setExplodeoffset(offset in points)

         #Set the column width for column charts or bar height for bar charts or take the default width of 36 points (1/2 inch)
         $psgraph->setColumnwidth

         #Set the number format for column charts or take the default (money)
         #Valid formats: money (whole dollars starting with a $) or d for the number of decimal places.
         #d0 is an integer. d3 creates three decimal places
         $psgraph->setFormat

         #Set the type size for the headers (column and bar charts)
         #The type size is not scaled with the graphic so that uneven scaling of horizontal and vertical dimensions
         #does not skew the type. The headers are in bold type. The default size is 9 point.
         $psgraph->setHeadertype(point size)

         #Set the type color for the headers. Default is black (0 0 0 1) (column and bar charts)
         ##The color is CMKY, entered as 4 numbers between zero and one, space delimited
         $psgraph->setHeadercolor(’C M Y K’)

         #Set the type size for the axis type (column and bar charts)
         #As with the headers, the type size is not scaled with the graphic
         #The default size is 8 points.
         $psgraph->setAxistype(point size)

         #Set the type size for the value type (column and bar charts) and callouts on pies.
         #As with the headers, the type size is not scaled with the graphic
         #The default size is 9 points for column and bar charts. 8 points for callouts on pies.
         $psgraph->setValuetype(point size)

         #Set the grayscale type color for values in bar charts
         #Usually black (0) for light-colored backgrounds and white (1) for dark-color backgrounds
         $psgraph->setValuecolor(grayscale value)

         #Set the background color (column and bar charts)
         #The color is CMKY, entered as 4 numbers between zero and one, space delimited
         #The default color is .3 0 .15 .09 (a light blue).
         $psgraph->setBackgroundcolor(’C M Y K’)

         #Export graphic
         #If you have
         #ImageMagick you can also generate any format that ImageMagick supports using its convert program. By default,
         #any export to a bitmap format (jpg, png, etc.) will be generated at 1200 dpi so that the rasterizaion of the
         #fonts is of good quality. To use one of these formats, set Gexport to the extension of that format:
         $psgraph->setGexport(extension)

         #write the graphic files
         #pies are written to a pies subdirectory, column charts to a column subdirectory and bar charts to a bars subdirectory
         #the subdirectories must be created before running the writeGraphic method
         #the return value is either 1 (for successful completion) or an error.
         #both eps files, and, if Gexport is set, the exported will be in the same directory
         $psgraph->writeGraphic

DESCRIPTION
       PSGRAPH is a module designed for mass creation of data charts for
       printing or on-line use.

       EXPORT

       None by default.
