  <p>Here is my code:-</p>
  <pre><code>var data = new google.visualization.arrayToDataTable(loadStageLeadGraphData);
                  var options = {
  
                      series: {
                          0: {
                              axis: 'distance'
                          }, // Bind series 0 to an axis named 'distance'.
                          1: {
                              axis: 'brightness'
                          } // Bind series 1 to an axis named 'brightness'.
                      },
                      chartArea: {
                          top: 55,
                          height: '40%'
                      },
                      axes: {
                          y: {
                              distance: {
                                  label: 'Leads'
                              }, // Left y-axis.
                              brightness: {
                                  side: 'right',
                                  label: 'Value (INR)'
                              } // Right y-axis.
                          }
                      },
                      vAxis: { format: 'decimal' },
                      hAxis: {
                          slantedText: true,
                      },
                      colors: ['#CBD570', '#FCC100']
                  };
  
                  var chart = new google.charts.Bar(document.getElementById('Lead_stage'));
                  chart.draw(data, google.charts.Bar.convertOptions(options));
