Hi Community,  
I am facing an issue with the indirection of power charts. I want to add dynamic tag bindings to my power chart. In the designer pens of the PowerChart is visible but in the perspective launcher pens disappears. Bindings have no error. I have shared the screenshot.

> Hi Community, I am facing an issue with the indirection of power charts. I want to add dynamic tag bindings to my power chart. Here I am sharing the steps with screenshots that I am following. Step 1: Selecting the status tag (sts) in the tag browser of power chart. Pen appears with the source: histprov:IgnitionDB01:/drv:kl\_cj2:/tag:vdc\_kl\_testinstances/cb/status/sts Step 2: Now I use expression of indirection binding. There is no error in the binding as it can be seen…
