  @harishv,

  You can create a websocket service in Angular app which establishes connection with your C-program and receives data. The received data should be parsed to the format accepted by CanvasJS to update the chart. Please check the code-snippet below that shows how to parse the data received from the websocket.

  
  .
  ngOnInit(): void {
    this.websocketService.connect();
    this.websocketService.messageReceived.subscribe((message: string) => {
      // message passed from the socket is in format { "value": 10 }. Parse to dataPoint format as per value returned from the socket service.
      let data = JSON.parse(message);
      this.dataPoints.push({
        y: data.value
      });
      this.chart.render();
    })
  }
  .
  

  You can download the working sample from here. Also, refer to this article for more information on creating websocket service in Angular.
