 *
 *  The contour lines are calculated only once and then redrawn to save plotting time.
 *  Make sure you add a new graph when your data changes. The contour levels can be defined in
 *  contourLevels, each elemt in the list represents a contour plane. You can also create contour

 *  value in your data. For logarithmic data, use createContourLevelsLog() to create contour levels
