We use your XamDataChart control in our application. For the x-axis we take CategoryDateTimeXAxis and for the y-axis NumericYAxis.

But we discover a strange illustration of the datachart now.
In our example a compression is displayed from 08:17:43 to 08:41:49.
This indicates from our point of view that many datapoints exist in this time period.
However, actual only one changed datapoint around 08:36:11 with the value 90 exists in this time period.
Could you explain me this behavior?

Due to the maximum size of attachements we have divided the screenshots of our example into 2 parts. I will give you the 2nd part as a separate post.

Best regards,
Hans
