@oneworld,

Adding and removing axis using addTo() and remove() respectively seems to be working fine. Please take a look at this jsfiddle.

If you are still facing any issue, kindly create a jsfiddle reproducing the issue so that we can look into it and help you out.

@oneworld,

remove() method doesn’t work on default axis, which means its not possible to remove axisX[0]/axisY[0].

@saul_romero,

Can you kindly create jsfiddle that reproduces the issue you are facing, which you have showed in the video.

The jsfiddle which you have provided seems to be working fine with JSON data and seems to be something different than the issue you have mentioned.

@arqu07,

You can fetch the latest row in database, parse it and add it to chart-dataPoints. Please refer the following links for more information on retrieving latest row from database.

@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.

@kinokatsu,

We are unable to see pan/reset button being shown on clicking ‘scale’ button.

Please check this.
