charts using php

问题:

i need to make charts (pie and bar) and working with php data. the data is JSON encoded.

what are the best ways to generate charts. i am right now looking at Google Chart api. is there anything better (read: easier) than this?

回答1:

google charts is nice, these are also excellent:

• amcharts (amcharts.com)

• open flash charts is one (http://teethgrinder.co.uk/open-flash-chart/)

• xml/swf charts (http://www.maani.us/xml_charts/)

• amcharts and xml/swf charts both have free versions.

回答2:

pChart ( http://pchart.sourceforge.net/) is a also pretty popular choice.

I've used it in the past with satisfaction.

If I have to find a new charting library/API I'd probably go with the Google Chart API, though.

The PEAR Image_Graph package is a very powerful tool to create graphs.

Check out the samples here http://pear.veggerby.dk/samples/.

Google Fusion is kind of new and does graphical representation of data. http://tables.googlelabs.com/Home

If you're using jQuery, JQuery Google Charting makes using Google Charts API very easy.
Also, Flot is very nice tool for plotting x/y charts, it does not provides pie charts, and lacks the concept of categories/datasets, but otherwise the most impressive.
