Disable Shadow in ChartJS Line

If you are using ChartJS to create a line graph and want to disable the shadow effect, then there are multiple methods to achieve it.

Method 1: Directly disable shadow in options

The simplest way to disable shadow effect in ChartJS line is to use the options property and set the shadow property to false. Here is an example:

var lineChart = new Chart(ctx, {
    type: 'line',
    data: data,
    options: {
        elements: {
            line: {
                tension: 0,
                shadow: false
            }
        }
    }
});

In the above example, we have set the shadow property to false in the elements option, which disables the shadow effect in the line chart.

Method 2: Create custom plugin to disable shadow

If you want more control over the ChartJS line chart and want to disable the shadow effect for multiple charts, then you can create a custom plugin. Here is an example:

Chart.plugins.register({
    beforeDraw: function(chartInstance) {
        var ctx = chartInstance.ctx;
        ctx.shadowColor = 'rgba(0, 0, 0, 0)';
        ctx.shadowBlur = 0;
    }
});

In the above example, we have created a custom plugin that sets the shadow color to transparent and shadow blur to 0. This disables the shadow effect in all ChartJS line charts.

Conclusion

By using either of the above methods, you can easily disable the shadow effect in your ChartJS line graphs. Choose the one that suits your needs the best.
