the critical point about convolution

i salute the whole community

i'm working on convolution, but there's a point I don't understand

I use the general formula of the convolution as follows :




and I draw the graphs accordingly, and after I draw, we need to Decouple them, find the space in between, and find the convolution.













this is how I draw the graphs

but I have a hard time about how to draw the h(t - τ) sign when I draw it, I can't understand because if I draw it, they already seem to overlap directly with x(t) almost like they're intertwined, but I think I did it wrong somewhere, I couldn't find it.

how are we going to draw h(t- τ), what should it be?
every help will be honored! thank you very much!
