[Xerte-dev] Re: Graphs and pies in 1.9

[Smith, John]

Hi,

D3 looks pretty straightforward; very similar to jQuery, but a lot more powerful than we need. If we migrate the editor over to HTML5 though this year then it would give us instant support for many more chart types...

For the current chart model I simply ported the flash code over just now to get the chart working in most browsers although IE8 and below will always be a problem. Even D3 won't work properly in IE8 without using the AIGHT library to shim IE8 up to bare minimum of HTML5 compatibility... It might be worth looking into adding in AIGHT anyway as I have already had to add in several bits of alternative code targeted at IE browsers only...

D3 is complicated as anything early on, but once you get the logic it makes sense (a little)

John Horton's also been looking into a few other javascript libraries for drawing graphs as he's done quite complicated ones in Flash which need looking at again.  I'll pass the link onto him.

(it was John Smith on the list who did the page model btw not the John here)

Ah ok, I have been experimenting with D3 (http://d3js.org/) and feel relatively confident I can make it draw basic graphs, wondered if that'd be useful
Nothing as complicated as that page shows though

John wrote the new page model - I think he used jQuery and drew the shapes on a canvas.

We were going to look into whether there was something else we could use for more complicated graphs but what he did works well for the simple ones used on the charts page

Hello,

In 1.9 what draws the graphs and pie charts?

Pat
