Scaling separately

Question

How do I scale the graph on the left, but have the text on the right side still be the same size and at the same position?

\begin{tikzpicture}
[ultra thick, font=\Huge, scale=1]
\draw[ultra thin] (-0,0) grid(3,6);
\draw (0,0)--(2,1)--(3,2)--(3,3)--(2,4)--(0,5)--(-3,6);
\draw (0,0) rectangle (2,1);
\draw (2,1) rectangle(3,2);
\draw (3,3) rectangle (2,4);
\draw (2,4) rectangle(0,5);
\draw (0,5) rectangle (-3,6);
\node [red,above, text width=5cm] at (7,2) {Sample Text \ Sample text};
\end{tikzpicture}

Answer 1

Put the parts you want to scale inside a scope:

\begin{tikzpicture}
[ultra thick, font=\Huge, scale=1]
\draw[ultra thin] (-0,0) grid(3,6);
\begin{scope}[scale=2]
\draw (0,0)--(2,1)--(3,2)--(3,3)--(2,4)--(0,5)--(-3,6);
\draw (0,0) rectangle (2,1);
\draw (2,1) rectangle(3,2);
\draw (3,3) rectangle (2,4);
\draw (2,4) rectangle(0,5);
\draw (0,5) rectangle (-3,6);
\end{scope}
\node [red,above, text width=5cm] at (7,2) {Sample Text \ Sample text};
\end{tikzpicture}

The node text wouldn't scale anyway because nodes don't scale unless you really, really want them to. But with the scale option on the overall picture then its position (7,2) would scale. So in this example, the only part that needs the scope is keeping the node at the exact same position.

(I also left the grid out of the scope, mainly to show that the scale only affects things inside the scope, but also because I wasn't sure how much of the diagram "the graph on the left" referred to.)
