Help Center Help Center. A pseudocolor plot displays matrix data as an array of colored cells known as faces. The surface is defined by a grid of x - and y -coordinates that correspond to the corners or vertices of the faces. Matrix C specifies the colors at the vertices. The color of each face depends on the color at one of its four surrounding vertices.

Current color Old color [0, 0. Another thing that changed starting in the Rb version is that the hold on and hold off automatically cycles through the colors. In the past, each new plot command would start with the first color blue and you would have to manually change the color. Now it will automatically move to the next color s. See below for how to manually adjust the colors. If using mesh x,y,z , to change the look of it you would want to change 'EdgeColor'. Note that the name of this colormap is "parula" while previous to Rb, it was "jet". The eight basic colors are known by either their short name or long name RGB triplets are also included. Long Name Short Name RGB Triplet blue b [0,0,1] black k [0,0,0] red r [1,0,0] green g [0,1,0] yellow y [1,1,0] cyan c [0,1,1] magenta m [1,0,1] white w [1,1,1]. Example of how to change the color using short names is below. You can easily do the same thing using the long names. Many times you want to have more control of what colors are used. For example, I may want some data points drawn in the same color as the curve. Or I have a piece-wise graph that I want to have all the same color. There are several ways to do this.

Create a new matrix containing the RGB triplets for red, green, and blue. The plot updates immediately with the new colors. To create a rectangular grid of vertices, specify X as either of the following:.

Specify different sets of colors and line styles — Create your own set of colors or line styles to further distinguish your data. Specify the cycling order of colors and line styles — Specify whether to cycle through all line styles before, after, or at the same time as the colors.

Help Center Help Center. To plot a set of coordinates connected by line segments, specify X and Y as vectors of the same length. To plot multiple sets of coordinates on the same set of axes, specify at least one of X or Y as a matrix. Use this syntax as an alternative to specifying coordinates as matrices. You can specify LineSpec for some x - y pairs and omit it for others. For example, plot X1,Y1,"o",X2,Y2 specifies markers for the first x - y pair but not for the second pair.

Many plotting functions have an input argument called linespec for customizing. Also, the objects returned by these functions typically have properties for controlling these aspects of your plot. The names of the arguments and properties can vary, but the values they accept typically follow a common pattern. Once you are familiar with the pattern, you can use it to modify a wide variety of plots. The following examples use the plot function to demonstrate the overall approach for customizing the appearance of lines. For a complete list of options for a specific plotting function, refer to the documentation for that function.

The following table shows several common display formats and examples of the formatted output for the date, Saturday, April 19, at PM in New York City. Because the default ColorOrder matrix has seven rows, the colors repeat after the seventh line. A good way to visualize this matrix is with a two-color colormap. Again, I think this is because I'm plotting an entire matrix. The properties apply to all the plotted lines.

Named palettes provide a convenient way to change the colors of a chart. Call the nexttile function with a return argument to get the axes object for the second tile. The length of the vector must match one of the dimensions of the matrix. Create a plot with a purple line that has circular markers.

Help Center Help Center. The default colors provide a clean and consistent look across the different plots you create. You can customize the colors if you need to.

Specify X and Y as any combination of row or column vectors of the same length. Specify colorarray as a matrix of RGB triplets or an array of color names such as ["red" "green" "blue"]. Before Ra: Use the caxis function, which has the same syntaxes and arguments as clim. Long Name Short Name RGB Triplet blue b [0,0,1] black k [0,0,0] red r [1,0,0] green g [0,1,0] yellow y [1,1,0] cyan c [0,1,1] magenta m [1,0,1] white w [1,1,1]. So this changes the color of each line to a single color. You do not need to specify all three aspects of the line. Thus, different objects with the same SeriesIndex value use the same color and line style, if applicable. This property can have one of three values:. Alternatively, call the polarplot or geoplot function. You can also specify one of several named color palettes. Another thing that changed starting in the Rb version is that the hold on and hold off automatically cycles through the colors. Here are some more. I haven't found a solution on here that works so far. Setting the color order for the figure before calling yyaxis sets the color for each y -axis. For example, if you specify only the marker, the plot displays the markers with the default color and no line.
