Hello,

 

I recently made a few charts in my web application with the Kendo UI for MVC and then I realized that the stacked area chart doesn't display the values the right way. The different areas are stacked, but not with the right date.

The data list structure is like this:

     Group: "LINE1", Date: "2017-01-01 00:00:00", Value: "210"

 

I think I have already found a similar question to this problem: http://www.telerik.com/forums/715942-chart-not-displaying-all-category-axis-values

Is this problem already solved or do I need to fill up my list with the same amount of data points for every group?

 

Thanks,

Stefan

Hello Stefan,

After different testing scenarios, I noticed that currently, the dataItem numbers have to match, as otherwise the data will be misaligned:

http://dojo.telerik.com/icAbI ( The 2. AAPL is missing the first month's data, but visually it is missing the last ones.)

I will forward this to the developer's team, to investigate if this is the same effect or it is a new issue which can be fixed.

Apologies for the inconvenience this may cause you.

Regards,
Stefan

Hello Stefan,

I received the report from the developer's team.

We introduced the property series.categoryField which will use the values compare to the categoryAxis.field which will use indexes.

If the series.categoryField is used, the data should be shown correctly even if the number of items is different:

Hello Stefan,

The following article is demonstrating how all of the Kendo UI related fields including the Kendo.MVC.dll can be updated:

http://docs.telerik.com/aspnet-mvc/introduction#upgrade

"Change the reference to the new Kendo.MVC dll. Verify that the dll refers to the correct ASP.NET MVC version."
