Setting a Border Width for Charts in AngularJS using ChartJS

I'm currently incorporating chart.js into my AngularJS project. I am attempting to define the borderWidth as 1px.

I have experimented with the following code:

this.chart = {
    title: 'Threat Trends',
    labels: ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'],
    series: ['Malware', 'Phishing'],
    data: [this.app.malwareSiteCountWeekly, this.app.phishingSiteCountWeekly],
    options: {
        legend: {
            display: true,
            position: 'bottom'
        }
    },
    borderWidth: 1,
    colors : [this.app.theme.primary, this.app.theme.secondary],
    type: 'bar'
};

Additionally, I implemented the following HTML snippet:

<canvas
id="bar"
class="chart chart-bar"
chart-data="$ctrl.chart.data"
chart-type="bar"
chart-colors="$ctrl.chart.colors"
chart-labels="$ctrl.chart.labels"
chart-series="$ctrl.chart.series"
chart-options="$ctrl.chart.options"
chart-dataset-override="preOverride">
</canvas>

Unfortunately, I continuously encounter issues like those shown in this https://i.sstatic.net/QpzFx.png. Can anyone provide me with some guidance on how to resolve this?

Answer №1

To adjust the border width for each dataset individually, follow axtck's example. Alternatively, you can set the default border width to 1 by using the following code snippet: 

Chart.defaults.global.elements.rectangle.borderWidth = 1;
.

It is important to include this line before creating your chart.

UPDATE: If you wish to customize the border width for just one of your charts, you can do so by configuring the rectangle element in the options and specifying the borderWidth like this:

options: {
    elements: {
        rectangle: {
            borderWidth: 15
      }
    }
}

Answer №2

To add a border to the specific dataset, define the border width within its settings.

Give this a shot:

sampleData: {
    datasets: [{
        borderWidth: 2,
        data: [this.dataset1, this.dataset2]
    }]
};
