I am working on recreating an image of an heat equation as shown below
I have mostly been successful, however I am still not sure how to add the squiggly lines. Is there also an easier way to make sure the labels 1,0,and 1, are properly aligned? In the figure they have the same baseline, but in my graph they vary.
Any other improvements or ways to create the displayed image are appreciated as always

@rafa11111 It is a very simple model where the temperature is g(x) at the x-axis then it decreases linearly with y until it reaches zero at y = 1. The plate is also insulated so the borders have a temperature of 0. That is the u = 0 ... parts =)

@N3buchadnezzar I added something in which they are aligned. The issue is that you were usinglabelin situations in which IMHO just nodes are the cleaner option.

I agree that nodes are cleaner, why did I not think of that. Sorry for still being a novice when it comes to tikz. Thanks again for a wonderful answer

You can create squiggly lines with something like
draw (0,0) to[out=90, in=-90] (1,1);.– Skillmon
Aug 12 at 12:38
You may use
pinand redefine pin on way as is described in 17.10.3 The Pin Option in TikZ & PGFmanula, pp 249 (v 3.1.4b)– Zarko

How is the first figure an "image of an heat equation"?
– rafa11111
Aug 12 at 23:55
@rafa11111 It is a very simple model where the temperature is g(x) at the x-axis then it decreases linearly with y until it reaches zero at y = 1. The plate is also insulated so the borders have a temperature of 0. That is the u = 0 ... parts =)
– N3buchadnezzar
Aug 13 at 8:36
Of course, but I cannot see how it is relevant to the question, since it is about the squiggly lines.
