The histogram in Layer 1 provides the center, spread, and skewness of the data, while the probability plot in Layer 2 indicates whether the data follows a normal distribution. While Mathematica does provide a combined VectorDensityPlot function, you'll have more control if you create the two plots separately and then combine them using Show. Divide a figure into two using subplot. INPUT: xy_data_array - list of lists giving evaluated values of the function on the grid; xrange - tuple of 2 floats indicating range for. Out of 148 colors in the CSS color list, there are 95 name collisions between the X11/CSS4 names and the xkcd names, all but 3 of which have different hex values. For example: cplot = ContourPlot[f, {x, -2, 2}, {y, -2, 2}];. To do this you provide Mathematica with a list of the two component functions, in curly braces, as in this example: Plot[{Cos[x], Sin[x]}, {x, 0, 10}, PlotStyle->{{Blue, Thick}, {Red, Thick}}]. ListPlot x1, y1 , x2, y2 , plots a list of values with specified x and y. To contour, you use the ContourPlot command which takes the general form:.

List(Contour|Density)Plot together with a legend that shows the Mathematica 7. Contour plot with contour lines colored using a continuous outcome variable (qsec) Instead of coloring the whole plot, it may be more desirable to color just the contour lines of the plot. There are many possible ways to do this. Mathematica is an exceptionally rich environment that goes beyond pure. For example, plots in this code will not give identical output in Mathematica 10, although they do in version 9:. Plotting: Plotting is usually fairly easy; the basic syntax is Plot [fx, {x, xmin, xmax}].
