Power Graphic - by Carlos Reche

This will create a pie graphic (set by type=5) with title as "Sex" and default skin. Let's see the other parameters: x1 = male y1 = 50 (quantity of males) x2 = female y2 = 55 (quantity of females) See how it's simple! :) For those who don't know, to create a query string you have to put an "?" at the end of the URL and join the parameters with "&". Example: "graphic.php?Parameter_1=Value_1&Parameter_2=Value_2" (and so on). You can set how many parameters you want. The boring step would be to create this query string. Well, "would be", if I didn't create a function to do that. :) Let's see an example of how you can use this function in a PHP document: ///// START OF EXAMPLE ///// title = "Sex"; $PG->type = "5"; $PG->x[0] = "male"; $PG->y[0] = "50"; $PG->x[1] = "female"; $PG->y[1] = "55"; echo '

'; // If you're going to create more than 1 graphic, it'll be important to reset the values before // create the next query string: $PG->reset_values(); ?> ///// END OF EXAMPLE ///// Here is a list of all parameters you may set: title => Title of the graphic axis_x => Name of values from Axis X axis_y => Name of values from Axis Y graphic_1 => Name of Graphic_1 (only shown if you are gonna cross data from 2 different graphics) graphic_2 => Name of Graphic_2 (same comment of above) type => Type of graphic (values 1 to 6) 1 => Vertical bars (default) 2 => Horizontal bars 3 => Dots 4 => Lines 5 => Pie 6 => Donut skin => Skin of the graphic (values 1 to 3) 1 => Office (default) 2 => Matrix 3 => Spring credits => Only if you want to show my credits in the image. :) 0 => doesn't show (default) 1 => shows x[0] => Name of the first parameter in Axis X x[1] => Name of the second parameter in Axis X ... (etc) y[0] => Value from "graphic_1" relative for "x[0]" y[1] => Value from "graphic_1" relative for "x[1]" ... (etc) z[0] => Value from "graphic_2" relative for "x[0]" z[1] => Value from "graphic_2" relative for "x[1]" ... (etc) NOTE: You can't cross data between graphics if you use "pie" or "donut" graphic. Values for "z" won't be considerated. That's all! Hope you make a good use of it! It would be nice to receive feedback from others users. All comments are welcome!
