Is there a way to initiate a timer from a clickable object in a graph? I am familiar with making a button and doing timeSincePress, but I’d like to define a variable as the time since an object in a graph has been clicked.

I think this should be possible using a Ticker, which is part of a Graph in Desmos, but I’m not sure exactly how (I’ve never used Tickers myself). The following link may help:

It is not actually just a ‘d’ … it’s ‘dt’ all together … It’s a special notation that you can use only inside the ticker and gives you the elapsed time from the last time that ‘Run’ was called. So you can add all the dt’s and get the total elapsed time from the start … U_updateTime(x) = t->t+x, so that’s what it does. So now t represents the total elapsed time and you can use it as you want.
