scale x axis?

[pjammer]

Thought I'd ask this here, as i heard about a Chart.scatter plugin that scales an x-axis but I then came here to the README, since I'm using the gem.

i got an error adding

<%= line_chart @data, {width: 1000, generateLegend: true, scaleSteps: 2} %>

and

<%= line_chart @data, {width: 1000, generateLegend: true, scaleOverride: true} %>

I'll dig more, but thought I'd ask this here.

1. Out of the box, does the x axis scale?
2. Is there a plugin architecture i'm unaware of to use if it doesn't? I.e., how easy is it to add chartjs plugins?

Good work and good gem.

The current version of this gem bundles Chart.js v1.0.2. It doesn't know about plugins; I imagine you could add a plugin by getting the asset pipeline to pick it up after Chart.js, but I haven't tried it.

The gem doesn't do anything to the x axis; you get whatever Chart.js gives you.

What sort of error are you seeing?

No error on scaleSteps: 2 example above anymore, i think i had a dodgy chartjs.scatter mucking up the assets dir. I got rid of it and this is the only error i am getting now, but i don't know what scaleOverride:true does anyways, just thought i'd report.

[airblade]

You didn't include the actual exception message so I'm not sure what the problem is. Could you post the message please?

However I suggest you leave out the scaleOverride: true altogether. I originally put it in because I wanted the y-axis scale handled differently in my app (see nnnick/Chart.js#132) – but now I think this gem should be a simple wrapper around Chart.js, without any extra functionality.

Closing this because I've upgraded the plugin (v3.0.0) to use Chart.js v2.1.4, which has a different way of scaling.
