Rails application using chart.js optins

I've got a rails application and I want to use char.js to generate some charts. That works fine.

But now I have to set up some option to configure chart options.

I want to customize the tooltip.

enter image description here

I want that the legend colors are the same like in the chart. How can I do this?

in case of this I have to do something like that:

    window.myLine = new Chart(weekdayChart).Line(weekdayChartData, {
        responsive: true,
        animation: true,

        legendTemplate : "<ul class=\"<%=name.toLowerCase()%>-legend\"><% for (var i=0; i<segments.length; i++){%><li><span style=\"background-color:<%=segments[i].fillColor%>\"></span><%if(segments[i].label){%><%=segments[i].label%><%}%></li><%}%></ul>"        });

problem here are the <%= because they are normaly rails outputs in the view ... how can I solve this problem?

If the file name ends with .js you are fine, no need to deal with <%=. However if the file ends with .js.erb, you are going to have problems.

Considering you don't need ERB in this case (you don't use it at all), I highly suggest renaming the file to end with .js
