Hi, I am working with a Power Chart component. I wish there was a sliding Trace I want two things: - Print the view using component action. - X Trace to have values at the time of printing. X Trace only shows values when your mouse cursor is hovering over the chart. Can't print using a button because of this. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/c/5/c59b314f5a7371e51934c0560f1980310dbea655.png) So, I have configured an onKeyDown event to trigger the RequestPrint action for the Power Chart. This way, whenever you have placed your mouse over the instant you want the X Trace to show values for on the table you can press a key and print the view. I don't think I am doing it right since it isn't working. I have added a script action to set the focus on the Power Chart component (self.focus()) because the onKeyDown event only triggers if it is in focus. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/9/7/97d02770ed3fe4a14cda4bd1e568c5419d505eef.png) Thank you in advance for your help! ---

If the onKeyDown event only triggers when the component is in focus, then placing a the self.focus() on the onKeyDown event won't trigger, and it won't gain focus...right? ---

You are right I have also tried onStart for the self.focus() script, that will not work either. ---

Good idea, I think you are right. I was able to fix this by wrapping the PowerChart on a Container and configuring the events on that container instead of the PowerChart. However, it will only work once, to make it work every time I had to use the onPointerMove event to trigger the self.focus() script.
