When working with the TcHmiLinechart I think I found a bug in the source code for the control in TcHmiLineChart.js

On the mouse over and mouse hover events the coordinates of x are written to both x and y: x: __this.__lineGraphData[i][j].x

In some new API version, Shutdown Listener is auto registered when created. This breaks the LetsEncrypt sample with the following error on Init() :

"Error while initialization: Cannot register listeners of the same type and in the same domain several times. A listener of type 'ITcHmiSrvShutdownListener' is already registered in domain 'LetsEncrypt'."

Two possible work arounds:

1. On Init(), set TcHmiApplication.AutoRegisterListeners to false
2. Remove _shutdownListener.OnShutdown += OnShutdown;

Manually registering OnShutdown allows custom logic to run on shutdown. But with auto register listeners defaulting to true, one cannot add in a custom even handler to run due to OnShutdown implicitly registering. What event handlers are automatically added to simple listeners like Shutdown?
