PHP Pie chart

[stelthius]

Hi guys i use a script to show me the quota a user is using and it shows a pie chart

 

Example -

 

instead of it being the pie chart i want it to show like this exampl below

 

 

Can anyone help me with this please also if you need to see code just let me know and ill show you what i use thanks and regards

[.josh]

Are you using some special library or 3rd party script to generate that?

[stelthius]

to generate what the pie chart or the graph ?

[cooldude832]

gdlibrary was used to develop the graphs, you need to look into GD deeply to discover how to make charts.

[stelthius]

im pretty sure GD wasnt used as i dont have GD installed mate :|

[cooldude832]

I'm 100% sure GD was used because php can not easily generate pictures without it

[stelthius]

well iknow i dont have GD installed so it musnt be, can you recomend any good tutorials or places to start reading mate ? as i need to work this one out and pretty fast too lol

 

[cooldude832]

well then u ain't making the graphs on your server try googles php graphing and u need GD installed

[stelthius]

the graph is being made on the server, it calls nothing from the out side world,

[cooldude832]

show us how its made then cause your lying about something here

[stelthius]

excuse me ? why would i be telling lies about how the script works that simply just doesnt make sense, i do NOT have GD installed and the script does NOT call any out of the server functions doesnt call images from out of the box either, please dont call me a liar for explaining what the script does.

[cooldude832]

then show the code.

[stelthius]

fair enough, you still have no rights to call me a liar,

Like I said you are a lier that class has in it

     	$im = @ImageCreateTrueColor($wStart, $hStart + $sStart);

[stelthius]

ok ill say this slower, my box does not have GD installed, i set up my box about 4 hours ago, i have not installed GD no-one has access to my box, unless CentOS 5.2 has GD in it then it isnt installed

[cooldude832]

well then your classes for generating graphs isn't running on your box???

[stelthius]

ok im gonna end this here as its obvious something isnt how it should be plain and simple i dont have GD installed, the script is running on my box, what more can i say its running it works, all i want to do is change the way it shows the data, sorry for bothering you!

 

 

Rick,

[.josh]

Hey guys no need to fight.  stelthius isn't necessarily lying; as he said, what's the point in lying about it? He may simply not know and he's just assuming it's not installed because he didn't go install it.  But nonetheless, stelthius, the following:

 

ImageCreateTrueColor

ImageColorAllocate

ImageFill

ImageFilledArc

ImageFilledRectangle

ImageFontHeight

ImageString

ImageSX

ImageSY

ImageCopyResampled

ImageDestroy

ImageJPEG

 

are in your script.  Those are all functions of the GD library, so you somehow do indeed have the GD library installed and enabled on your system.  You had to have installed apache/php or maybe a package like WAMP or XAMPP or something, maybe it came with the bundle. Who knows? But the bottom line is that you do have it installed, because your script wouldn't run without it.

 

Check out what the GD library has to offer, in the way of doing what you want. 

[stelthius]

Thanks for your reply Crayon, as i was saying tho i installed CentOS 5 on my box around 4 - 5 hours ago so unless its in there then im clueless as no one else has access to the box lol wierd :/

[tibberous]

1) You don't have to install GD to have it, it's like the yahoo toolbar That said, it is a GD function which means you are probably running GD, and you can find out for sure by using the phpinfo() function.

 

2) You don't have to have GD to make an image on the server. There are tons of other libraries, and you don't even need a library, because you could run something like Image Magick command line and then route the image.

 

3) In a world where people are generally very tactful, it's sometimes funny to see something blatantly hostile and completely unprovoked.

1) Yes you do it could be part of the installation you used (such as wamp xamp uniform server)  and yahoo toolbar needs to be installed.

 

2) It isn't image magick because of the functions being used

 

3) I am not hostile I just hate when people are stubborn about something and they don't even take the time to check if a prediction is correct.

[stelthius]

well one thing i can say for sure im just looking for a way to make the quota show the second way rather than the pie chart lol

[cooldude832]

that being said I go back to my original statement that you need to use GD to generate the images as needed.

 

Since this class looks like it wasn't written by you then this will be a challenge to do ti without any help.

 

I suggest you google php graphing with GD tutorials as I suggested 20 post ago.

[DarkWater]

Let's settle this once and for all.  Stelthius, no one touched your box, it's just the PHP has GD bundled already. =/  And it's not so easy to magically present data in a different fashion.  You're going to need the background image, first of all, and a "circle" image that you will need to calculate the location of based on percentages.

[stelthius]

yeah i have all the images i made them earlier in hope that this was going to be an easy task and cooldude i did take notice of you and i did google what you suggested
