I am using the Rad Cartesian Chart control in my project.
ItemSource is bounded to a Chart Data that is an Observable Collection.
The value X value (Category ) is the time and Y is value of the data (element that is set to sinuses )
The Chart Data is cleared every 20 sec - a cycle and the new data is add from time=0 re-plotting.
In some scenarios (Such as dragging of an element on screen) an additional series is plotted where y= const.
Once the cycle is competed all lines are cleared and a new plot starts with no problem.
Adding values to Chart Data and clearing it is all by the UI thread.
Do you have a idea for what may cause this?
I am attaching screen shots hope this will c
