Add interactive charts to your RoR applications using RoR Gem for FusionCharts.

Download Free Trial

Create Line, Area, Pie, Bar, Column, Gantt and over 150 charts for your web application using the Ruby on Rails gem for FusionCharts. Unlike other charting libraries that only allow creation of static images with low resolution, our charts are completely interactive and responsive on all screen sizes. Moreover, the gem works with Ruby Hashes allowing you to let go of JSON data or JavaScript objects. Simply write your implementation in Ruby, fetch data from your MySQL server and directly create charts which are responsive, interactive, and support zooming, panning, APIs, animation, drill-downs, real-time updates, and full exporting of charts & dashboards, all in your own server!

Our Ruby on Rails gem comes with event support for mouse, keyboard, and more, enabling you to add charts in runtime during any lifecycle phase of the application. All our charts are mobile first by default, and responsive across all devices. Further, all charts & graphs are tested and built for millions of data points, without any performance issues.


  • Easily fit our plugin into RoR’s MVC paradigm.
  • Enjoy support for key FusionCharts features like annotations, macros, themes, image-export, and more.
  • Execute projects without writing separate API for JavaScript applications.
  • SQL or NoSQL, connect your chart directly to database of your choice.
  • Add data in a variety of ways, JSON, XML, or to Ruby Hashes.

#Filename: app/controllers/dashboard_controller.rb

class DashboardController < ApplicationController

  def index

    @chart ={
        width: "600",
        height: "400",
        type: "mscolumn2d",
        renderAt: "chartContainer",
        dataSource: {
            chart: {
            caption: "Comparison of Quarterly Revenue",
            subCaption: "Harry's SuperMart",
            xAxisname: "Quarter",
            yAxisName: "Amount ($)",
            numberPrefix: "$",
            theme: "fint",
            exportEnabled: "1",
            categories: [{
                    category: [
                        { label: "Q1" },
                        { label: "Q2" },
                        { label: "Q3" },
                        { label: "Q4" }
                dataset: [
                        seriesname: "Previous Year",
                        data: [
                            { value: "10000" },
                            { value: "11500" },
                            { value: "12500" },
                            { value: "15000" }
                        seriesname: "Current Year",
                        data: [
                            { value: "25400" },
                            { value: "29800" },
                            { value: "21800" },
                            { value: "26800" }



In order to render the chart, use the render method in the specific view

<!-- Filename: app/views/dashboard/index.html.erb -->

<h3>My Chart</h3>
<div id="chartContainer"><%= @chart.render() %></div>
