ChartKick Charts constantly loading and mixing up with other graphs on page Rails

Question

Ok, this sound strange, but it is actually happening in a App that I´m building.

I´m totally blank about why this is happening and below is a description of the problem and samples of my code.

On my users/show.html.erb I have few graphs that are rendered in nav-tabs on the show.html.erb through partials. That is working fine and the charts are rendering in each tab as they should do. But then there is this row of charts that is also rendered from a partial called _dashboard_part.html.erb. If I comment the dashboard partial out all the other graphs are working fine, but if I uncomment the dashboard_part partial the previously mentioned graphs are taking extreme time to load and some of them are squeezing and appearing in the graphs in the _dashboard_part.html.erb partial.

So there must be some conflict of some type to those graphs and partials, but I haven't been able to figure it out. So I really need help to figure this out.

The graphs in the _electro_part.html.erb partial (see below) are the once that seems to be conflicting with the _dashboard_part.html.erb partial.

Edit

Ok while I was inspecting the user/show.html.erb I noticed that when I hit the Electro tab this part of the last 3 charts in the _dashboard_part.html.erb changes from for example data-highcharts-chart="4" to data-highcharts-chart="42". I´ve no Idea why those 3 charts are changing when I hit the electro tab, but it must be a related to this strange mixup.

this is the graph part of my users/show.html.erb were the partials are rendered.

<hr>

 <%= render 'users/shared/dashboard_part' %> #This is the part were the conflict seems to be happening, it´s all good when I comment this part out

Answer 1

DAMN. It took me 2 days to find out what happens. I ran into the same issues.

Short and simple: You have to set the id of the chart on your own. Otherwise the ajax call will confound the charts.

If you want to know what really happens: https://github.com/ankane/chartkick/issues/193

So just do something like this:

<%= line_chart data,
               id: random_charkick_id,
               width: "200px", height: "80px" %>

and in your helper:

def random_charkick_id
    return 'chart-#'+(Random.rand(10000)).to_s
  end

I hope this answer is not too late for you.
