Is there a way to dynamically adjust the Y-axis ticks in a chart.js graph? I attempted to modify them using the following commands:
this.chartOptions.scales.yAxes[0].ticks.min = 10;
this.chartOptions.scales.yAxes[0].ticks.max = 18;

Make sure to call the chart.update() method after modifying the chart options. If you need more information, refer to the Updating Options section in the Chart.js documentation.
Feel free to test the code snippet below and click the Update button to observe the changes:
function updateYAxis() {
chart.options.scales.yAxes[0].ticks.min = 20;
chart.options.scales.yAxes[0].ticks.max = 100;
chart.update();
}
