When zoom quickly, found the scales.x.max < scales.x.min

See the onZoomComplete function. When the message is shown in console, the zoom range still has valid data, but the chart is empty.
I am using version '"chartjs-plugin-zoom": "^2.0.1",'

My zoom config is:

    zoom: {
      zoom: {
        mode: 'xy',
        drag: {
          enabled: true,
        },
        pinch: {
          enabled: true,
        },
        scaleMode: 'xy',
        onZoomComplete: (context) => {
          const chart = context.chart;
          const xScale = chart.scales.x;
          if (xScale.max < xScale.min) {
            console.log(xScale);
          }
          chart.update();
        },
      },
    }

The console output is (min 969, max 257):

I'm curious why do you have chart.update() in the onZoomComplete? Does removing that change anything?

[dabeibao]

No. I tried to swap the max/min and call chart.update(), but nothing changed. Forgot to remove this debug code.

I was not able to reproduce this with samples. Can you create a reproduction?
