Chartjs Line chart streaming stops when browser tab is not active #191

Chart stops streaming when browser tab is not active. Here is picture of my chart and code. You can see that in below image, very few datapoints are added into the chart when browser tab is not active ,and once the tab is active then the chart starts to do streaming as per configured refresh time. Please help me on this.

ReactJS Code

scales: { x: { type: "realtime", ticks: { color: "#cdd5d9", }, realtime: { refresh: configData.Refreshtimer, // onRefresh callback will be called every 100 ms // onrefresh callback to update datasets onRefresh: function () { currObj = { x: Date.now(), y: Math.random(), }; chartRef.current.data.datasets[0].data.push(currObj); } }, }, },

it seems to be a feature of the browser that slows down on inactive tabs. it should be configurable per tab.
