comment Adding annotations to plot with vertical leader line to the curve
Thank you for that, lots very elegant... I'll have to go through step by step and see if I can figure out what you did, but looks really good

comment Adding annotations to plot with vertical leader line to the curve
Sorry, I am creating a list of points along the way that I want to ADD to the elevations and distances so as I am riding, I could see, I'm here at the bridge and this is where I am in the elevation profile.

comment How to have shaded grid entries
I appreciate the pedagogical note, that IS important. Sadly, those kinds of subtle nuances are lost on about 99% of my students (pardon my cynicism!) I'm happy if they actually understand a dB is a tenth of a Bel!

That looks fantastic, and simple to implement!

comment Intersecting parabolas in an image
I tried to do a "brute force" parabola creation on the un-edited image. I'm no mathematician but I could NOT get the last parabola (farthest to the left) to match the bridge, but the one farthest to the right matched "perfectly". You could be right, but based on the answer below, my intuition tells me that the distortion WILL require correction...

Amazing answer, I will have to experiment with edge detection for other photos!

Yes, you got me there... I got the name from my friend (a Calgarian!) I guess even if you live there you may know all the names... I don't know all the bridge names for Edmonton (where I live). Thanks for the correction and link!

Thanks for that, that's a great resource. I will have to see if there is data online for the bridge in my friend's photo (St. George's bridge in Calgary, AB)
