To check the type of chart being used in Chart.js, you can access the 'type' property of the chart object. Here's how you can do it:
- First, you need to have a reference to the chart object. If you have created your chart using Chart.js, you may already have a variable storing the chart object.
For example, if you create a line chart like this:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 |
var ctx = document.getElementById('myChart').getContext('2d');
var myChart = new Chart(ctx, {
type: 'line',
data: {
labels: ['Red', 'Blue', 'Yellow'],
datasets: [{
label: '# of Votes',
data: [12, 19, 3],
backgroundColor: [
'rgba(255, 99, 132, 0.2)',
'rgba(54, 162, 235, 0.2)',
'rgba(255, 206, 86, 0.2)'
],
borderColor: [
'rgba(255, 99, 132, 1)',
'rgba(54, 162, 235, 1)',
'rgba(255, 206, 86, 1)'
],
borderWidth: 1
}]
}
});
|
- You can then check the type of chart by accessing the 'type' property of the 'myChart' variable:
1
|
console.log(myChart.config.type); // This will log 'line' |
By checking the 'type' property, you can determine if the chart is a line chart, bar chart, pie chart, etc.
