chartjs line disable shadow

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.
