Hello Synfusion Support!

We encounter a problem with the trackball on different axis types.

On a CategoryAxis, we see values like this (integer):


With the same ViewModel, we see on a DateTime Axis values like this (double): 



We use double as property type but our values are "integers" without decimal places. 

Furthermore, we have the effect that with a DateTime axis, if we have more complex bindings with arrays, no values are displayed at all. 

Our ViewModel is like this: 

YBindingPath = "Columns[7]",
ItemsSource = "Deltas[1].sdc[2]",

On a CategoryAxis, we have no problem. Everything is fine & works!

Identical ViewModel but with a DateTime axis, we see this. The chart works, but Trackball shows nothing. 


Do you have any ideas or suggestions?

best regards, 
Sascha

Hi Sascha, 
 
Greetings from Syncfusion. Please find the response below.  
 
Query 1 : With the same ViewModel, we see on a DateTime Axis values like this (double). We use double as property type but our values are "integers" without decimal places.  
Query 2: Furthermore, we have the effect that with a DateTime axis, if we have more complex bindings with arrays, no values are displayed at all. 
 
We have analyzed these queries and checked the scenarios with our sample. But it works fine with trackball label value in DateTimAxis. Can you please check with the sample in the following location? 
 
 
If you still face any problem, can you revert us by modifying the attached sample based on your application scenario, this will help us to provide you a better solution at the earliest.  
 
Thanks, 
Muneesh Kumar G.
