---|
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! |
