![]() You can adjust the transparency with the alpha function. We can select a pre-set lighting algorithm which is good for curved surfaces. % Put a point to indicate where the light source is (for reference) Alternatively, you can also use camlight. You can place a light source at a particular location. You can control the shading of surface objects using the shading function. You can change colormaps either interactively: The default colormap for a figure is JET. This could be acheived with something like this: Theme Copy h rectangle ('Position', x1, y1, x2, y2. It is represented by an M-by-3 matrix, where each row represents a color (in RGB). 1 Link Commented: Walter Roberson on at 10:17 Accepted Answer: Chris L'Esperance It would be helpful to create a transparent, rectangular patch with rounded corners. To see what the current colormap is for the current figure, use the command colormap: colormap It exists in all MATLAB graphics, but you see the effect of it mostly in 3D surfaces and images. ColormapsĬolormaps are MATLAB's way of mapping levels/intensities/values to colors. In fact, there are a number of cam* commands for manipulating the view camera. camorbit(180, 0) % 180 degrees about Z-axis view(50, 40) % azimuth and elevationĪnother way of changing the view is to use commands like camorbit. You can do it interactively from the figure window:īut you can also do it programmatically using the view command. In a 3D plot, you can change the orientation of the view. Let's first focus on the three different types of 3D plots:įor the rest of the tutorial, we'll take a look at each of these topics in detail. MATLAB's 3D plotting capability is just as versatile as the 2D plots. Legend( 'Signal', 'Location', 'Northwest') 'MarkerSize', 10) Īdding titles, labels, legends is as simple as using the commands title, xlabel, ylabel, legend. In the next section, we'll talk more about these properties. In fact, you have much more control by providing specific "properties" to the command. Just highlight a variable that you want to plot and click on the drop down menu to bring up the Plot Selector.Īs with many other MATLAB functions, plot takes additional arguments allowing you to customize the plot. You can also access these functions directly from the Workspace Browser. Use PLOT for single color, single marker size scatter plots. ![]() H = SCATTER(.) returns handles to the scatter objects created. SCATTER(AX.) plots into AX instead of GCA. SCATTER(.,M) uses the marker M instead of 'o'. SCATTER(X,Y,S) draws the markers at the specified sizes (S) SCATTER(X,Y) draws the markers in the default size and color. Length(X)-by-3 matrix, it directly specifies the colors of the Same length as X and Y, the values in C are linearly mapped If S is empty, theĬ determines the colors of the markers. MATLAB draws all the markers the same size. Vector the same length a X and Y or a scalar. S determines the area of each marker (in points^2). SCATTER(X,Y,S,C) displays colored circles at the locations specifiedīy the vectors X and Y (which must be the same size). To learn how to use these functions, use help or doc help scatter % doc scatter SCATTER Scatter/bubble plot. Here's a good summary of these plotting routines. A properly written MATLAB application that needs to use a fixed-width font should set FontName to FixedWidth (note that this string is case sensitive) and rely on FixedWidthFontName to be set correctly in the end-user's environment.MATLAB provides a variety of plotting routines, both in 2D and 3D. This eliminates the need to hard code the name of a fixed-width font, which may not display text properly on systems that do not use ASCII character encoding (such as in Japan where multibyte character sets are used). set(text_handle,'FontName','FixedWidth').If you want text to use a fixed-width font that looks good in any locale, you should set FontName to the string FixedWidth: ![]() To display and print properly, this must be a font that your system supports. A string specifying the name of the font to use for the text object. FontName A name, such as Courier, or the string FixedWidthįont family. Generally, setting this property to italic or oblique selects a slanted font. ![]() MATLAB uses this property to select a font from those available on your particular system. Curly braces | italic | obliqueĬharacter slant. This section lists property names along with the types of values each accepts. Rectangle properties control the appearance and behavior of a rectangle object. To change the default value of properties see Setting Default Property Values.
