canvasjs.min.js:209 Uncaught TypeError: Cannot read property 'getTime' of undefi

[reset]

Hello everyone,
I have a problem with the creation of my line chart.
I use a lot of data to create the graph, about 30,000 points, the problem is that if I have few points in the array (example 5,000) this is displayed correctly, but when I have many more it sends this error:

canvasjs.min.js: 209 Uncaught TypeError: Cannot read property ‘getTime’ of undefined
     at p._processMultiseriesPlotUnit (canvasjs.min.js: 209)
     at p._processData (canvasjs.min.js: 206)
     at p.setLayout (canvasjs.min.js: 189)
     at p.render (canvasjs.min.js: 201)
     at window.onload (chance_mp.php: 80)

[reset]

other peculiarity, if I use the php function in example to create random data the graph is displayed.

<? Php
$ limit = 50000;
$ y = 100;
$ dataPoints = array ();
for ($ i = 0; $ i <$ limit; $ i ++) {
$ y + = rand (0, 10) – 5;
array_push ($ dataPoints, array (“x” => $ i, “y” => $ y));
}
?>

if I use mine it only works with a few points

@reset,

I use a lot of data to create the graph, about 30,000 points, the problem is that if I have few points in the array (example 5,000) this is displayed correctly, but when I have many more it sends this error:

The issue is happening due to the incorrect format of dataPoints being passed to the chart-options. Removing redundant numbers between the objects of dataPoints array should work fine in this case. Please take a look at this Updated JSFiddle.

Format of dataPoints that you have passed:
dataPoints: [{"y": 24},{"y": 24},34,{"y": -315}]

Valid Format:
dataPoints: [{"y": 24},{"y": 24},{"y": 34},{"y": -315}]

other peculiarity, if I use the php function in example to create random data the graph is displayed.

$ i, “y” => $ y));
}
?>

if I use mine it only works with a few points

This is working fine as the format of dataPoints being generated is proper.
