Passing in custom options about chartkick HOT 10 CLOSED

To keep chartkick as flexible as possible, I added the library option, so you can now do:

<%= line_chart series, library: {legend: {position: "left"}} %>

It's not as clean as your proposed implementation, but I'd like to keep library-specific options separate for now.

The options are pretty limited right now (just min and max), but I'm open to adding ones that are requested often.

Cool! I understand you'd like to have specific options over inserting a hash to override the defaults?

Correct, I'd like the options to be independent of the charting library. This way, we can do

:min => 0

vs

options.vAxis.viewWindow.min = 0

Thanks! Actually, I think this is even nicer.

I'm trying to pass the lineTension: 0 option to charts.js so I can get straight lines between points instead of Bezier curves. I've tried
line_chart series, library: { lineTension: 0 }
and
line_chart series, library: { options: { lineTension: 0 }}
with no effect.

Any suggestions for the right syntax in this situation?

Thanks!

I am facing a similar problem as @genlighten. Did we find any results?

from chartkick.

Someone found a solution to your problem @genlighten?

from chartkick.

@genlighten I had the same problem, but the following workaround seems to work:
Chart.defaults.global.elements.line.tension = 0.001;

Setting it to 0 doesn't work, but 0.001 does.

from chartkick.

If anyone else finds this issue, I figured out how to get straight lines with Chart.js 2.7.0 and chartkick 2.3.5:

line_chart data, library: { elements: { line: { tension: 0 }}}

Setting it to 0 works fine now, they must have fixed that issue.
