Thank you, in advance, for your response. >01. http://img11.imageshack.us/img11/668/14251790.png This one can be done using ContourPlot. To get something equivalent you would want to specify the ContourLabels option to obtain the numbers that label the contour lines and specify coloring options to get a monochrome background. >02. http://img577.imageshack.us/img577/42/81367303.png This one can also be done with built-in functions. Here you want to use ListPlot to plot the data making use of the PlotStyle option to specify colors. DensityPlot can be used to create the legend and Show is used to combine the two graphics into a single graphic. Look up ColorData in the documentation center to see what standard coloring schemes are already available. Additionally, there is an example in the documentation of using DensityPlot to create a legend. If you don't care for the color schemes built-in, you can always create your own with the built-in functions. A nice display of the built-in color schemes can be found in the documentation center by searching on guide/ColorSchemes.
