Hey!

I've just downloaded pChart and created my first radar graph.

I'm extremely impressed and I'll most likely implement it on my web page (and of course pay you guys a well deserved donation).

However, I have one concern. When I load the image in my browser, there's a roughly two second delay (waiting for server...)

Why is that?
Is it very cpu intensive?
Is there a way to reduce the wait, like in increasing the step size in some iteration or something?

I've turned off antialisasing in the beginning and turn it on again just before the final image is rendered.

$myPicture = new pImage(400,400,$MyData);
$myPicture->Antialias=false;

$myPicture->Antialias=true;
$SplitChart->drawRadar($myPicture,$MyData,$Options);

This helps a little bit, but not much.

I only input five arrays, each with three floating point values. So there shouldn't bee too much data either.
I'm using Hostgator VPS.

Any advice is highly appreciated

Hi,

Same for me, on a cpu 1ghz, I need 2.5 seconds to generate (not for load from the web page) a 900x400 graph.
Cause is GD library who needs cpu time for generate image.

If you make a little debug, all waste of time is by GD functions used in pchart class.

Tnx for sharing this
Do you know which changes I can make to the library for the load time to decrease?

No idea.
And a web search give me no results.
