Pie chart slices not scaling properly

[oks...@gmail.com]

Hi

 

I am using the following code

 

http://chart.apis.google.com/chart?chf=ffff00&cht=p3&chs=700x300&chd=t:33522.5,31680,24922.2,1643.4&chco=0000ff,ff0000,228b22,c71585&chl=Type1 (36.53%)|Type 2 (34.52%)|Type 3 (27.16%)|Type 4 (1.79%)

 

 

to generate a pie chart. If you copy and paste this into a browser you get the chart but clearly the pie slices are not correctly shown. i.e. they all look around 25% when the data is 33522/31680 oor around 35% each and then for type 4 data=1643.4 or approx 2% then pie slice is the same size and the rest.

 

What is wrong with my code?

 

Thanks

 

Nick

Hmmm....seem to have "accidently" solved this by dividing all the numbers by 1000 - then it works. So have no idea why the largish number are not handled by the chart routine - seems odd to me.

If you add &chds=a to your original URL it will correctly scale the Pie chart.
