phpCharts Gallery | Wizard | Document Document + Variables Summary Variable Name Summary Default Value Type axis_width defines thickness of the x-y axis 2 Integer bar_gap gap between two bar 10 Integer bar_width width of a bar, if chart width is assigned bar width will be calculated on the basis of chart width for vertical bar chart and chart height for horizontal bar chart 20 Integer bg_color background color of the chart FFFFFF Hexa Code chart_height height of the chart; if not assigned then value will be calculated from bar_width for horizontal bar chart; for circular charts height will be calculated from the radius 300 Integer chart_thickness to display the chart in 3D view thickness need to be assigned 10 Integer chart_width width of the chart; if not assigned then value will be calculated from bar_width for vartical bar chart; for circular charts width will be calculated from the radius 300 Integer data this defines the points to draw chart, it can be assigned with simple array or associate array(key value pairs); while assigning associate array keys will be termed as header of tables Null Array/Associate Array data_type types of data user provide, this is associated with data source; array, csv, xml, MySql, MSAccess, PostgreSql, MSSql Null String database_name if data source is a database then name of the database need to be assigned Null String delimiter if data source is csv then delimiter need to be assigned as: ",", ":", "|" ,(comma) Char dimension dimension of the chart 2D or 3D 2D String direction direction of the chart, it can be horizontal(h) or vertical(v) and valid for different bar charts V Char doughnut_width width of the doughnut ring 20 Integer file_path path of the csv/xml data file, it can be absolute or real path Null String group_col name of the column which is associated with header name of the data table, represents x-axis in bar charts and slice in circular charts Null String header_height height of the chart header, assigned header height and title character height will be compared and the greater one will be considered as actual header height 20 String increment constant difference between values used for ploting chart 1 Integer incrementx constant difference between values of x-axis used for ploting XY chart 1 Integer incrementy constant difference between values of y-axis used for ploting XY chart 1 Integer label display actual value in the chart, by default it will not be displayed false Boolean label_font_size label font size 1 Integer legend_align alignment of legend, it can be one of the following: left, right, top, bottom bottom String line_col color of the xy axis 000000 Hexa Code line_gap gap between two points in the line chart; if chart width for vetical and chart height for horizontal is assigned then line gap will be calculated on the basis of chart width/chart height for respective chart direction 20 Integer margin margin around the chart 20 Integer marker display marker for line chart, by default it will be displayed true Boolean output_type different format charts can be generated, value must be one of the following: png, jpg, gif, html, pdf html String password if data source is a database then password for the database need to be assigned if any null String percent display bar charts in percent Null Integer pie_gap gap between each slice of different exploded circuler charts(pie, doughnut) 10 Integer query if data source is a database then query to select data from the database must be assigned Null String radius radius of different circular charts(pie, doughnut) 100 Integer series_col associated with header column name of the data table, defines sub division of each group column Null String server_name if data source is a database then server name need to be assigned localhost String title title of the chart Null String title_font_size font size of the title 3 Integer txt_col color of the text displayed on chart 000000 Hexa Code type type of the chart, must be one of the following: bar, pie, bar_mix, pie_explode, doughnut, doughnut_explode, xy, min_max, histogram, line Null String username if data source is a database then user name of the database need to be assigned, if any Null String value_col associated with header column name of the data table, defines actual value for drawing charts Null String ymax_value changing maximum value to user defined value Null Integer + Methods Summary Method Summary __construct assign default value to the variables once object is created isValidDataType Verifies the data provided by the user;
