Hi Emil, 

 

Sorry for the inconvenience caused, given your stack trace we suspect that the interval property may not fall within the data range. Having said that we created a simple sample with axis minimum set to 0 and maximum as 500 and set interval as 0.1 this made the sample to hang (because it will create 5000 labels and we did this just to stress test the control) but still we didn’t get any exception.  

 

Since we are not aware of your exact scenario, it is not possible for us to replicate the issue at our end, can you please help us by modifying the sample which we attached below to replicate your scenario, and this will help us to provide you a better solution at the earliest.

Let us know if you have any concerns.  

 

Thanks,

hi, 

.I found the problem. I had double value on yAxis. my app is multilingual and if data is stored with dot as decimal separator(in English language) and user changes to German which accept comma , it was double value like 467,354656768 and it since conversion is not valid double, it was 467354656768 and defining 10 interval caused this problem. thank you for the hint, it was helpful to figure this out
