---|

---|
| 21 | * PowerGraphic creates 6 different types of graphics with how many parameters you want. You can |
---|
| 22 | * change the appearance of the graphics in 3 different skins, and you can still cross data from 2 |
---|
| 23 | * graphics in only 1! It's a powerful script, and I recommend you read all the instructions |
---|
| 24 | * to learn how to use all of this features. Don't worry, it's very simple to use it. |
---|
| 25 | * |
---|
| 26 | * This script is free. Please keep the credits. |

---|
| 31 | |
---|
| 32 | INSTRUNCTIONS OF HOW TO USE THIS SCRIPT (Please, take a minute to read it. It's important!) |
---|
| 33 | |
---|
| 34 | |
---|
| 35 | NOTE: make sure that your PHP is compiled to work with GD Lib. |
---|
| 36 | |
---|
| 37 | NOTE: You may create test images using a form that comes with this script. Just add a "showform" |
---|
| 38 | as a query string. (Example: "graphic.php?showform") |
---|
| 39 | |
---|
| 40 | |
---|
| 41 | PowerGraphic works with query strings (information sent after the "?" of an URL). Here is an |
---|
| 42 | example of how you will have to send the graphic information. Let's suppose that you want to |
---|
| 43 | show a graphic of your user's sex: |
---|
| 44 | |
---|
| 45 | <img src="graphic.php?title=Sex&type=5&x1=male&y1=50&x2=female&y2=55" /> |
---|
| 46 | |
---|
| 47 | This will create a pie graphic (set by type=5) with title as "Sex" and default skin. |
---|
| 48 | Let's see the other parameters: |
---|
| 49 | |
---|
| 50 | x1 = male |
---|
| 51 | y1 = 50 (quantity of males) |
---|
| 52 | x2 = female |
---|
| 53 | y2 = 55 (quantity of females) |
---|
| 54 | |
---|
| 55 | See how it's simple! :) |
---|
| 56 | For those who don't know, to create a query string you have to put an "?" at the end of the URL and join |
---|
| 57 | the parameters with "&". Example: "graphic.php?Parameter_1=Value_1&Parameter_2=Value_2" (and so on). You |
---|
| 58 | can set how many parameters you want. |
---|
| 59 | |
---|
| 60 | The boring step would be to create this query string. Well, "would be", if I didn't create a function to do that. :) |
---|
| 61 | Let's see an example of how you can use this function in a PHP document: |
---|
| 62 | |
---|
| 63 | |
---|
| 64 | ///// START OF EXAMPLE ///// |
---|
| 65 | |
---|
| 66 | <?php |
---|
| 67 | |
---|
| 68 | require "class.graphics.php"; |
---|
| 69 | $PG = new PowerGraphic; |
---|
| 70 | |
---|
| 71 | $PG->title = "Sex"; |
---|
| 72 | $PG->type = "5"; |
---|
| 73 | $PG->x[0] = "male"; |
---|
| 74 | $PG->y[0] = "50"; |
---|
| 75 | $PG->x[1] = "female"; |
---|
| 76 | $PG->y[1] = "55"; |
---|
| 77 | |
---|
| 78 | echo '<img src="graphic.php?' . $PG->create_query_string() . '" />'; |
---|
| 79 | |
---|
| 80 | |
---|
| 81 | // If you're going to create more than 1 graphic, it'll be important to reset the values before |
---|
| 82 | // create the next query string: |
---|
| 83 | $PG->reset_values(); |
---|
| 84 | |
---|
| 85 | ?> |
---|
| 86 | |
---|
| 87 | ///// END OF EXAMPLE ///// |
---|
| 88 | |
---|
| 89 | |
---|
| 90 | |
---|
| 91 | Here is a list of all parameters you may set: |
---|
| 92 | |
---|
| 93 | title => Title of the graphic |
---|
| 94 | axis_x => Name of values from Axis X |
---|
| 95 | axis_y => Name of values from Axis Y |
---|
| 96 | graphic_1 => Name of Graphic_1 (only shown if you are gonna cross data from 2 different graphics) |
---|
| 97 | graphic_2 => Name of Graphic_2 (same comment of above) |
---|
| 98 | |
---|
| 99 | type => Type of graphic (values 1 to 6) |
---|
| 100 | 1 => Vertical bars (default) |
---|
| 101 | 2 => Horizontal bars |
---|
| 102 | 3 => Dots |
---|
| 103 | 4 => Lines |
---|
| 104 | 5 => Pie |
---|
| 105 | 6 => Donut |
---|
| 106 | |
---|
| 107 | skin => Skin of the graphic (values 1 to 3) |
---|
| 108 | 1 => Office (default) |
---|
| 109 | 2 => Matrix |
---|
| 110 | 3 => Spring |
---|
| 111 | |
---|
| 112 | credits => Only if you want to show my credits in the image. :) |
---|
| 113 | 0 => doesn't show (default) |
---|
| 114 | 1 => shows |
---|
| 115 | |
---|
| 116 | x[0] => Name of the first parameter in Axis X |
---|
| 117 | x[1] => Name of the second parameter in Axis X |
---|
| 118 | ... (etc) |
---|
| 119 | |
---|
| 120 | y[0] => Value from "graphic_1" relative for "x[0]" |
---|
| 121 | y[1] => Value from "graphic_1" relative for "x[1]" |
---|
| 122 | ... (etc) |
---|
| 123 | |
---|
| 124 | z[0] => Value from "graphic_2" relative for "x[0]" |
---|
| 125 | z[1] => Value from "graphic_2" relative for "x[1]" |
---|
| 126 | ... (etc) |
---|
| 127 | |
---|
| 128 | NOTE: You can't cross data between graphics if you use "pie" or "donut" graphic. Values for "z" |
---|
| 129 | won't be considerated. |
---|
| 130 | |
---|
| 131 | That's all! Hope you make a good use of it! |
---|
| 132 | It would be nice to receive feedback from others users. All comments are welcome! |
