Mapping Toolbox™ extends the functionality of the geoplot (MATLAB®) function. It adds support for displaying points, lines, and polygons with coordinates in any supported geographic or projected coordinate reference system (CRS). Depending on the type of axes, the function displays data into different map projections.Z = peaks (n) returns the peaks function evaluated over an n -by- n grid. If you specify n as a vector of length k, MATLAB ® evaluates the function over a k-by-k grid. example. Z = peaks (Xm,Ym) returns the peaks function evaluated at the points specified by Xm and Ym. The sizes of Xm and Ym must be the same or be compatible.

I would like to set the transparency of LINE objects in my figures. I use the ALPHA command to set the transparency of objects in my figure. However, LINE objects do not respect ALPHA values even though I am using the OPENGL renderer.9. You can use arrow from the file exchange. arrow (Start,Stop) draws a line with an arrow from Start to Stop (points should be vectors of length 2 or 3, or matrices with 2 or 3 columns), and returns the graphics handle of the arrow (s). Edit: @Lama is also right, you can use annotation but you need to take into account the plot limits.Description example yline (y) creates a horizontal line at one or more y -coordinates in the current axes. For example, yline (2) creates a line at y=2. example yline (y,LineSpec) specifies the line style, the line color, or both. For example, yline ( [12 20 33],'--b') creates three dashed blue lines. exampleTo add comments to MATLAB code, use the percent ( %) symbol. Comment lines can appear anywhere in a code file, and you can append comments to the end of a line of code. For example: % Add up all the vector elements. y = sum (x) % Use the sum function. To comment out multiple lines of code, use the block comment operators, % { and %}.

However, you can use the hold on command to combine multiple plots in the same axes. For example, plot two lines and a scatter plot. Then reset the hold state to off. x = linspace (0,10,50); y1 = sin (x); plot (x,y1) title ( 'Combine Plots' ) hold on y2 = sin (x/2); plot (x,y2) y3 = 2*sin (x); scatter (x,y3) hold off. When the hold state is on ...
