Have Both \filldraw and Theta Marked on Graph

[Dustinsfl]

Since I have theta marked on the graph, fill draw doesn't show anymore. How can I have both?

\filldraw[left color=gray,right color=green, draw=green!50!black] -- (3mm,0mm) arc (0:30:4mm) -- cycle;
\draw[->] (-1.5,0) -- (1.5,0) coordinate (x axis); 
\draw[->] (0,-1.5) -- (0,1.5) coordinate (y axis);
\draw (0,0) circle (1cm);
\foreach \x in {-1,1}
\draw (\x cm,1pt) -- (\x cm,-1pt) node[anchor = north] {$\x$};
\foreach \y in {-1,1}
\draw (1pt,\y cm) -- (-1pt,\y cm) node[anchor = east] {$\y$};
\draw -- node[right = .5 pt] {$\theta$}(0.9,0.35);
\draw[very thick, black] (0,0) -- (.70710678,.70710678);

Hi dwsmith, :)

I checked your code, and to me the command \filldraw seem to work, although I am not sure as to what you expect out of it. What part of the circle do you want to color?

Kind Regards,
Sudharaka.

See page 6 and you will see that fill draw didn't work.

I understand the problem now. For some reason I saw the desired output in the preview but not in the pdf file. I have changed the code(highlighted in red) and hope it works now. :) Is this the intended output?

\begin{tikzpicture}\filldraw[left color=gray,right color=green, draw=green!50!black] [COLOR=#ff0000](0,0) [/COLOR]-- (3mm,0mm) arc (0:30:4mm) -- cycle;\draw[->] (-1.5,0) -- (1.5,0) coordinate (x axis); 

\draw[->] (0,-1.5) -- (0,1.5) coordinate (y axis);
\draw (0,0) circle (1cm);
\foreach \x in {-1,1}
\draw (\x cm,1pt) -- (\x cm,-1pt) node[anchor = north] {$\x$};
\foreach \y in {-1,1}
\draw (1pt,\y cm) -- (-1pt,\y cm) node[anchor = east] {$\y$};
\draw -- node[right = .5 pt] {$\theta$}(0.9,0.35);
\draw[very thick, black] (0,0) -- (.70710678,.70710678);\end{tikzpicture}

In order to have both \filldraw and theta marked on the graph, you can use the \filldraw command to fill the desired area on the graph and then use the \draw command to draw the theta symbol at the desired location. This way, both the desired area and the theta symbol will be visible on the graph. Alternatively, you can also use the \node command to add the theta symbol to the graph.
