I have brought this topic over from php6 and mysql5 as it seems more appropriate to JS than php...........
The question was:.......
I was looking at an Iberdrola electricity invoice and working out how I would code the php to produce one, which was relatively straightforward, except at one point they put a bar chart to show the previous year's consumption....which got me wondering - is there any facility in php to produce something similar?
This would be easy enough:
x........x
x........x...x
x....x...x...x
x....x...x...x
x....x...x...x
________
J...M..M..J
A...A..A..U
N...R..Y..L
BUT WOULD LIKE TO SOMETHING A BIT MORE FLASHY!
....and HartleySan replied thus:....
With newer browsers, you can very easily create gradients to somewhat spice up your graphs.
As a more practical solution, you may want to consider a library like Google Chart Tools:
https://developers.google.com/chart/
I believe they use the canvas element, so an HTML5-compatible browser is required.
Edit: Apparently the charts fall back to VML graphics for non-HTML5 browsers, so maybe they work in all browsers.
------------------------------------
I reckon that package is very useful to developers.
