Multiple colors on BarChart

[Ghriim]

Hi,
I'm trying to set different colors for each bar on my bar chart.
I use Peity to show small graph with 2 bars on for a periode n and the other for perdiode n-1 so i need to have 2 differents colors for each of my bars.

I haven't find a way to do so.

Thanks.

I'm afraid that's not possible at the moment. It could be though, I'll have a think about how it might be achieved.

Perhaps a peity.colours array similar to the one in the pie chart implementation? Charts iterate through those colors, and some accessor function allows a dev to set it to be whatever they want?

I was thinking you could pass a function which would receive the value, index and all values (much like Array#forEach - https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Array/forEach callback signature) like so:

$("span").peity("bar", {
  colours: function(value, index, all) {
    // return a colour
  }
})

It could also work for other options... The only problem is that you can already pass a function which acts in a different way - http://benpickles.github.com/peity/#tips.

I just pushed a branch with support for passing multiple colours to a bar chart - https://github.com/benpickles/peity/compare/multicoloured-bar-charts

Take a look and let me know what you think.

I just released version 1.0.0 which includes support for setting per-bar colour.
