Override beforeDatasetsDraw

Chart.pluginService.register({
    beforeDatasetsDraw: function(chart) {
        for (dataset of chart.config.data.datasets) {
            for(data of dataset._meta[chart.id].data) {
                data._model.skip = false;
                data._model.tension = 0;
            }
        } 
    }
});

Instead of null values try with ‘0’, or the minimum value possible.

x-labels: 08:00, 09:00, 10:00, 11:00, 12:00
y-line: 12, 0, 10, 0, 15
y-bar: 0, 25, 0, 30, 0

It is not able to process null. Hope this helps.
