To start, I am familiar with making a Graph card, with several sensors. Then after the Graph card is displayed, clicking on the sensor name(s), to hide the corresponding graph(s).
What I would like, is to (reverse the issue,) create a Graph card, with several Sensors, but only a select few sensors, being displayed, when the card is opened. And the rest of the sensors available to click on, to be display.
The above pic, is what I would like to see, when the graph is first displayed.
