Tooltips callbacks doesn't work

[BlowofDeath]

Hi, i've tried to set a label using callbacks funcction, but i'm getting errors. Am i doing something wrong or is it an issue with library?

const chart = new fabric.Chart(options as fabric.IChartConfiguration);

  chart.set({
    chart: {
      options: {
        tooltips: {
          callbacks: {
            label: function (tooltipItem, data) {
              let total = 0;
              data.datasets[tooltipItem.datasetIndex].data.forEach((item) => {
                total += Number(item);
              });

              const label = data.datasets[tooltipItem.datasetIndex].label;
              return `${label}: ${tooltipItem.yLabel} of ${total}`;
            },
          },
        },
      },
    },
  });

From what I can see you made a mistake, you should be setting options.plugins.tooltips.callbacks.label and not options.tooltips.callbacks.label as described here. Please let me know if that works.

That doesn't help, chart-js-fabric use "dependencies": {"chart.js": "^2.9.3",}
2.9.3 documentation tells you to use options.tooltips.callbacks.label, but i tried to use options.plugins.tooltips.callbacks.label and i'm got same error. I also tried to use onClick

 chart.set({
    chart: {
      options: {
        onClick: () => {
          console.log('click');
        },
      },
    },
  });

it doesn't work as well.

It works, only when i set this functions using fabric.util.chart.setDefaults, but i need this to be set only on specyfic chart.

  fabric.util.chart.setDefaults({
    options: {
      tooltips: {
        callbacks: {
          label: function (tooltipItem, data) {
            let total = 0;
            data.datasets[tooltipItem.datasetIndex].data.forEach((item) => {
              total += Number(item);
            });

            const label = data.datasets[tooltipItem.datasetIndex].label;
            return `${label}: ${tooltipItem.yLabel} of ${total}`;
          },
        },
      },
      onClick(e, elements) {
        const pointedElement = this.getElementAtEvent(e)[0];
        pointedElement &&
          chart.canvas.fire('openChartViewModal', {
            options: options.chart,
            pointedElement: {
              datasetIndex: pointedElement._datasetIndex,
              index: pointedElement._index,
            },
            datasourceInfo: options.datasourceInfo,
          });
      },
    },
  });
