I have a chart where some dates on the x-axis have no values, and I would like to exclude them. Below is an image of my chart:

Here is the code snippet for the options in my Chart JS:

var options = {
                            responsive: true, 
                            maintainAspectRatio: false,
                            elements: {
                                line: {
                                    fill: false
                                }
                            },
                             style: {
                                  strokewidth: 10
                                },
                               
                             title: {

                            } 
                };

I'm looking for assistance with this issue. Thank you!

Before feeding your series/data into the chart, make sure to apply a filter

let data = [...];
data = data.filter(entry => entry[0] && entry[1]);
