gRaphael Js: where can I find tutorials to produce data charts (pie, bar, etc)
Where can I find tutorials to produce data representations on the 开发者_运维百科web with gRaphael? There seem to be no documentation on line.
Many Thanks
I really would recommend against graphael just from personal experience. I looked at it and got stuck several times during my implementation (ex, simple things like axis labels require hacks like setting text at specific spots), and the physical x-axis scaling/ticks that is visible (at least for bar charts that I've tried) don't seem related to the data, as if there is some internal axis that you can't see. I could not find a single graph example that actually had even the minimum # of components a professional graph has (labels, legends, etc), so for me it's just a prettier 'sparklines'. All in all, a lot more trouble than it's worth, plus any documentation you find will be minimal at best.
I would look into jquery options (great documentation and easy browser support for js)
- highcharts is #1 if it's for personal use, very beautiful, interactive, and easy to use
- flot, nice looking though not as interactive or as many options
- jqplot, inspired by flot. this is my current choice. there's a huge amount of stuff you can do with this. interactive and professional looking, looks like a good sub for highcharts if the licensing fee is too much.
Flash charts (beautiful but flash is a no-no these days):
- Open flash charts - It's not too bad to implement and I used it before I decided to switch to jqplot. Very nice looking charts, but my graphs needed to grab data from the server more dynamically, and I decided js was a better option to do it.
- Amcharts - easily make good looking graphs via XML data.
There doesn't seem to be that many beginner tutorials, but here's a couple of reasonably introductory text with examples:
