@yansonalvin97,

You can change chart-type whenever there is change in dropdown. Please take a look at this jsfiddle.

Larry,

1. is it different from just add empty objects as default to each dataPoint? also no need to delete it

Both are same. However empty object in a dataSeries can affect axis-range.

2. as you can see in your solution, Xaxis is changed due to this solution. why its happens?

That’s because of empty object. To avoid this you can add a dataPoint with y-value set to null. Please take a look at this updated jsfiddle.

@natasha11,

Please take a look at this sample project for creating dynamic charts using data from MySQL database in PHP. Also, please refer to this documentation page for creating Dynamically Updating Charts from JSON API & AJAX.

If this doesn’t suit your requirements, kindly share a sample project with sample data over google-drive or onedrive so that we can understand it better and help you out.

Larry,

You can add an empty object to dataPoints to show legend and remove the empty object when you update dataPoints. Please take a look at this jsfiddle.

@jwk,

Please check the path of the file you are linking and it should work fine if its linked properly. It would be helpful for us to understand your scenario better if you could share sample project (over google-drive or onedrive) which you are running in local web server so that we can look into it and help you out.

Marco,

AS you are using $.get(), which is jQuery method, adding jquery to your code should work fine. Please take a look at this tutorial on getting started with jQuery.

@ipapop,

Thanks for bringing it to our notice. You were facing the issue due to trailing comma in chart-options data: data, // random generator below. Removing trailing comma should work fine in your case. We have updated the code in docs, please try with latest code or try removing trailing comma data: data // random generator below

@InvisibleSandwich,

You can scale-up or scale-down the chart before exporting using exportChart method and reset it back soon after exporting. Please take a look at this jsfiddle.

@vincent,

You can have one colorSet within a chart, as of now. However if you are trying to have different colorSets for each dataSeries, you can try setting color in dataPoint level. Please take a look at this jsfiddle.

@faulduff,

In JavaScript, date object can be created in 4 ways. new Date(), new Date(year, month, day, hours, minutes, seconds, milliseconds), new Date(milliseconds), new Date(date string).

In your case i.e new Date(year, month, day), month counts from 0 to 11 i.e. 0 corresponds to January and 11 corresponds to December. Changing the month according to JavaScript date-object should work fine in your case.

For different JavaScript date formats please refer this article.

Please take a look at this JSFiddle for a working example with sample code.

Ryan,

You can position custom DOM wherever you want on the chart with the help of convertValueToPixel and convertPixelToValue methods. Please take a look at this jsfiddle where many custom texts are positioned as indexLabels.

@tcodeuser,

ui.newTab.index() gives you the index of the current tab, which is 2 in this case. However you are trying to access charts[index] and charts2[index], i.e. charts[2] and charts2[2] which doesn’t exists as the length of both charts and charts2 is 1. Rendering chart1 and chart2 (or charts[0] and charts2[0]) on ‘tabsactivate’ should work fine in this case. Please take a look at this updated jsfiddle.

Still, if you are facing any issue please create a jsfiddle with sample data and share it with us so that we can understand your code better and help you out.
