Is there total value for context.dataset ?

Hi! I'm calculating total value on the fly to get percentage in the label. Like this

Chart.defaults.plugins.tooltip.callbacks.label = function (context) {
  const total = context.dataset.data.reduce((x, y) => x + y, 0);
  const currentValue = context.parsed;
  const percentage = ((currentValue / total) * 100).toFixed(2);
  return `${currentValue} (${percentage}%)`;
};
Chart.defaults.plugins.tooltip.callbacks.title = function (context) {
  return context.label;
};

But maybe there is already total value of dataset?
