title: Cartopy: Why can't add feature LAND working?
body: <p>I want to plot the average intensity of Sea Surface Temperature map using cartopy.</p>
  <p>Here is the result:<br />

  <p>I want to clarify that I want to fill ocean map with average intensity and the land map with face color setting.</p>

  <li><p>The figure size is not changing even though I tried several size sets. I couldn't make it bigger.</p>
  </li>
  <li><p>Regarding cfeature.land, I set the facecolor at 0.5 but it didn't seem to work. It works at the extended plotted area. I notice that 'Average Intensity' variable is plotted over the land map instead of facecolor. I need to specify the levels or contour if I want to differ it from ocean.</p>
  </li>
  </ol>
  <p>The real problem is I have several variables and all of them has inconsistent land colour because I need to re-write each level of color.</p>
  <ol start="3">
  <li>Additional problem, how to plot (degree) symbol? In this code, I simply make Deg C because I cannot make the superscript of the degree symbol</li>
  </ol>
  <p>Does anyone have any ideas, on how to plot this map properly?</p>
