Help with refreshing data automatically

[newuseruser]

Hello I created a chart here is my source code:

Highcharts.getJSON('/Sensor_eins.txt', function (data) {

// Create the chart
Highcharts.stockChart('container', {
rangeSelector: {
selected: 1
},

title: {
text: 'AAPL Stock Price'
},

series: [{
name: 'AAPL',
data: data,

tooltip: {
valueDecimals: 2
}
}]
});
});

how can I activate that the data is automatically refreshed every 5seconds??

Hello,

You can use chart.events.load() callback function to add interval after the chart is loaded and use Highcharts.getJSON() method again to load the latest version of the data. You only need to add logic to add only new points.

API: https://api.highcharts.com/highcharts/chart.events.load

Let me know if you have any further questions!
Best regards!
