In other words, if the contour interval is 6, a contour will represent all the points on the grid where the values are equal to 0. Another contour at 6, another at 12 and so on. So we will pick 6 . WXP offers several different types but the primary types are color fill and line contours. Line contours are just the lines at each contour value.
Fill contours fill in each area between contour lines with a different color.
So one color will represent all values in the grid between 0 and 6. The next color will represent all values between 6 and 12 and so on. Fill contours don't print well on black and white laser printers so it is often recommended to use line contours when printing. Now the contouring will procede in the window that opened earlier. The plot is Temperature.
