Sorting doesn't work when dealing with dates

[Arthur]

I've had this issue for two years (StackOverflow post), and today I checked if the latest version of kendo fixed this issue and it looks like it didn't.

Sorting a chart against a string field works fine, as demonstrated in the following string dojo.

But when I try and sort it against a date field it simply doesn't do anything, as demonstrated in this date dojo.

 

Is there something I'm missing?

Hi, Arthur,

Thank you for the provided examples and screenshots.

The reason for this behaviour is that the category axis is a date axis and it automatically aggregates and plots the data:

https://docs.telerik.com/kendo-ui/controls/charts/elements/date-series#date-series-in-categorical-charts

If you want to keep using a date axis, you can use the categoryAxis.reverse property or set the chart categoryAxis type to "category" which cease to aggregate and behave as a date chart and will plot all of the available points so you will need to add a label format as well just like the string example you have provided:

Here is an updated Dojo for your reference that pictures both of these options:

Let us know in case of further questions.

Kind Regards,
