Why isn't data loading on my Plotly chart?
1
I have this webapp where the backend is built on Flask. I'm sending some numbers from my Python Flask script to my frontend using SocketIO, but i can't see the data loading on my chart.
I tried to debug it but there appears to be no error in my code. Any advice? Thanks in advance!
$(document).ready(function() {
//connect to the socket server.
var socket = io.connect('http://' + document.domain + ':' + location.port + '/test');
var numbers_received = ;
//receive details from server
socket.on('newnumber', function(msg) {
console.log("Received" + msg.number);
//maintain a list of ten numbers
if (numbers_received.length >= 1) {
numbers_received.shift()
}
numbers_received.push(msg.number);
numbers_string = '';
for (var i = 0; i < numbers_received.length; i++) {
numbers_string = numbers_string + '<p>' + numbers_received[i].toString() + '</p>';
}
$('#log').html(numbers_string);
});
Plotly.plot('chart',[{
y:[numbers_received],
type:'line'
}]);
var cnt = 0;
setInterval(function(){
Plotly.extendTraces('chart',{ y:[[numbers_received]]}, [0]);
cnt++;
if(cnt > 500) {
Plotly.relayout('chart',{
xaxis: {
range: [cnt-500,cnt]
}
});
}
},15);
});
