Empty statistics and JS console errors

Hi @fox mulder

I Tested the issue in Simpletest.me, i am not getting any error related to JS.

I had the error. I corrected it.

In /simpleads/js/simpleads.charts.js

It says

function getLineChartOptions(xAxesLabel, yAxesLabel) {
    return {
      type: 'line',
      data: {
        labels: [],
        datasets: []
      },
      options: {
        responsive: true,
        tooltips: {
          mode: 'index',
          intersect: false,
        },
        hover: {
          mode: 'nearest',
          intersect: true
        },
        scales: {
          xAxes: [{
            display: true,
            scaleLabel: {
              display: true,
              labelString: xAxesLabel
            }
          }],
          yAxes: [{
            display: true,
            scaleLabel: {
              display: true,
              labelString: yAxesLabel
            }
          }]
        }
      }
    };
  };

Guided by the Chart-js 3.x migration docs, I changed it to

function getLineChartOptions(xAxesLabel, yAxesLabel) {
    return {
        type: 'line',
        data: {
            labels: [],
            datasets: []
        },
        options: {
            responsive: true,
            plugins: {
                tooltip: {
                    mode: 'index',
                    intersect: false
                }
            },
            hover: {
                mode: 'nearest',
                intersect: true
            },
            scales: {
                x: {
                    display: true,
                    title: {
                        display: true,
                        text: xAxesLabel
                    }
                },
                y: {
                    display: true,
                    title: {
                        display: true,
                        text: yAxesLabel
                    }
                }
            }
        }
    };
}

and it worked.

It should probably be further updated, but doing this, I got rid of the js errors.
