I use ng2-charts 3.1.2 and with using of line chart label callback and following settings:

lineChartOptions = {
    scales: {
      xAxis: {
        type: 'time',
        ticks: {
          source: 'labels',
          autoSkip: false,
          maxRotation: 0,
          callback: ..my logic..
        },
        ...
      },

I keep getting overflowing labels when they are too close or there is some time gap etc. Even after lot of callback modifications I ended up just skipping all but first and last labels if there is unusual gap detected. Is there any lib method like shouldSkipLabelByDefault(labelIndex) i can access from callback or any other clean approach?

Problematic X-axis labels look like this:

Tried:

• Lot of callback modifications, always was found some dataset with overflowing labels
• switching type, source, autoskip .. dataset chart settings
