Rails: Remove white border from Pie Chart using Chartkick Gem

问题

Is there a way to remove the white border from the pie chart slices by adding an option to the library?

I've got a snippet of the code I used to create this chart.

<%= pie_chart monthly(current_user.events), colors: colors_group, width: "200px", height: "200px", library:{animation:{easing: 'easeOutQuad'}} %>

Thank you in advance!

Try setting the borderWidth option to 0:

<%= pie_chart monthly(current_user.events), colors: colors_group, width: "200px", height: "200px", library: {animation: {easing: 'easeOutQuad'}, elements: {arc: {borderWidth: 0}}} %>

You can find more options for Chart.js element configuration on their docs page.

Hope this helps!
