Graphics, Figures & Tables ⇒ TikZ Scaling Inconsistency

[LaTexLearner]

I am trying to teach myself TikZ scaling for number lines. Apparently, there's something about scaling the x- and y-axes that I don't understand.

Why are the vertical tick marks different sizes for these two number lines if the y-scale is 1.8 for the first number line but the x- and y-scales are both 1.8 for the second?

This is the problem:

Code: Select all

\begin{tikzpicture}[xscale=3][yscale=1.8]

As result, you gave just xscale as option. The [yscale=1.8] would be a second set of options, so in a second argument, but tikzpicture takes only one argument in square brackets, which has a list of key=value settings.

So, the correct way is:

Code: Select all

1
\begin{tikzpicture}[xscale=3,yscale=1.8]
