Can Chart takes in an activerecord object and convert it into a json automatically

with nvd_pie I am getting a nv is not defined error

Do we need '//= require nvd3' at Installation stage?

Option for stacked bar chart

I am using this gem (chart js) for my generating radar and bar charts on pdf. It works great. However, I couldn't find the option for stacked bar chart. Are they included in the gem?

I'm looking for this chart:

Currently, this is the chart I have generated.

I tried to look for alternative such as chart-js-ror. It has the stacked bar chart option but rendering pdf causes a lot of issues, particularly label inconsistency and responsive problems. And also the pdf generated has some blurred lines. Just wonder if there's such option and sharper image for the chart in this gem. Thanks.

Data example for Radar?

Hello, sample data renders JS error on radar types.

I am using a copy paste from the sample data.
Where can i get information on how to build the JSON object needed to generate the Radar graph?
Thanks,
