@jonasbui1476,

By changing few lines of code according to your json format, its possible to render multi-series chart based on the key (label) from JSON. Please check this jsfiddle.

@saul_romero,

data.sort((a,b)=>a-b); works on array but not on array of objects. You need to sort it manually to handle it. Please chek out the code-snippet to sort datapoints below.

for (var i = 0; i < dataPoints.length - 1; i++) {
  if (dataPoints[i].x > dataPoints[i + 1].x) {
    var temp = dataPoints[i];
    dataPoints[i] = dataPoints[i + 1];
    dataPoints[i + 1] = temp;
    i = 0;
  }
}

Please check this JSFiddle for complete code.

Also please refer to this documentation page for tutorial on dynamically updating chart from JSON data.

@arqu07,

The issue is in updateChart function. It fails to enter for-loop as value of x (var x = i;) is same as the value of result.length. Read data from database, store it in another variable (lets say result1) and then push that to dataPoints as shown below.

var updateChart = function () {
    for(var y=0; y < result1.length; y++){
	dataPoints.push({label:result1[y].Date, y:result1[y].Value2});
    }
    x=y;
    chart.render();
};

Please check this updated project

@kinokatsu,

Thanks for the info. It seems to be some CSS issue, we will look into it further. As of now, you can work-around using CSS-display property. Please check this jsfiddle.

@kinokatsu,

Sorry for the inconvenience, due to some technical issue it has happened and your post will be restored soon.

We checked with the jsfiddle and observed that pan/reset buttons won’t appear on clicking ‘Scale-Change’ button. Please check this image.

If you are still facing any issue, please reproduce the same in jsfiddle so that we can look into it and help you out.

@jonasbui1476,

Yes, its possible to render multiseries chart from single json based on some key/id. Please check this jsfiddle for an example on the same.

Please refer this page for info on date-formats in JavaScript, the date-format in your json is not a valid one.

@Arqu07,

Unless we look into your code, we can’t predict what went wrong in it. Can you kindly create a sample project and share your code, so that we can look into it and help you out.

@saul_romero,

Sorting data before calling chart.render method in updateECG() will work fine in your case. Kindly refer this page for tutorial on array-sorting in JavaScript.

Kiran,

This feature is not available as of now. But by splitting it into multi-series, you can achieve the same. Please Please check this jsfiddle.
