comment How convert list of numbers to list of points on x-axis?
You may easily combine Plot and NumberLinePlot. For example, Show[{ Plot[2 Sin[x] + x, {x, 0, 15}], NumberLinePlot[{2, 4, 7, 10, 13, 6}, Spacings -> 0]}]

comment How to make the final result a number and change dynamically with the button action?
Your code, as pasted, does not work. There is an imbalance of brackets within the CreateDialog function.

comment InfiniteLine Woes
@MarcoB, That's just what tripped me up. And I was in an unusual hurry too.

comment InfiniteLine Woes
Thanks. The syntax even matches that of Line. I'm surprised I didn't try it.

What about this? (from the documentation) Graphics[InfiniteLine[{0, 0}, {1, 1}], Frame -> True]

ImageCorners reference.wolfram.com/language/ref/ImageCorners.html may be useful for step 1.

Algohi, That seems to be a general solution to the problem.

comment VertexLabels, EdgeLabels and the direction of the arrows on a directed graph
You should be able to find solutions to all of your problems by consulting the documentation. See GraphicsGrid,VertexCoordinates, EdgeStyle, etc...

comment Font presentation difference between version 9 and version 10
Looks fine on my MacBook with Mathematica v. 10.0.2 The font is heavier than your upper image, but far smoother than your lower image. Shouldn't Georgia be a serif font? Your lower image is sans serif.

comment Dynamically Update both a HorizontalGauge range and the value
This seems to offer more general solution (which is great because I want to add additional scales), but the lower marker sometimes jambs, sitting immobile while the upper marker is being dragged.

comment Fine precision control in IntervalSlider
Basically, I want students to be able to explore a number line by zooming in or out at will. I plan to have multiple Horizontal Gauges on display at once. But I am still thinking about the functionality, the operations I want students to be able to apply.

Good point. I hadn't tried adjusting the interval size!

comment What is Association[Rule[“ID”,number ] and how it is used
I'm puzzled. Look at TreeForm[ds1] and then ds1[[1]]. How can you get the full list of data out of the dataset?

Mr.Wizard You are indeed perceptive. Yes, I was.

+1 for using Union instead of Sort and Union

comment Automatically convert pairs of directed edges to an undirected edge?
Would you clarify how /. {{_[a_, b_], __} :> a <-> b, {x_} :> x} works? I don't fully understand _[a_, b_] but it seems to be an opaque variation of belisarius' Rule[a_,b_].
