I am trying to plot a few points on top of a live image preview, but my code returns an error of "Line cannot be a child of Image." Does anyone know of a way to plot on top of a Live Image, similar to the image
I had the following code (which works) that does an imshow raster data and then plots red dots on top of a list of markers (I.e. the base layer is an image of stars, and the overlay is red dots that mark them). ThemeCopy function plot(this) imshow(WORLD.image, [0 1]); ho...
options below). Nose is at top of plot; left is left; right is right. Using option 'plotgrid', the plot may be one or more rectangular grids. Usage: >> topoplot(datavector,EEG.chanlocs); % plot a map using an EEG chanlocs structure >> topoplot(datavector, 'my_chan.locs'); % re...

line() and plot() do not accept angles as input. If you want to draw by angle, use pol2cart([0 angle], [0 linelength]) and add the x/y coordinates of the origin of the line to the result. Also make sure you use ThemeCopy axis image so that you get square pixels for the imag...
使用plot 函数绘制两个信号,并设置不同的颜色和线型。 使用hold on 保持当前图形窗口,以便在同一图中绘制多个信号。 使用xlabel, ylabel, title 和legend 设置图表的标签和标题。 使用text 函数添加文本标签。 运行代码 你可以将上述代码复制到MATLAB中运行,它将生成一个类似于你提供的图片的信号对比图。 在这里插入...
In this chapter, the display image in MATLAB is presented and described. In this regard, several examples and exercises for each section of the chapter are presented. The exercises that include writing the codes, executing them, and achieving the results need to be done by students to master ...
line(X,Y,Z,'PropertyName',PropertyValue,…)画出由参数x,y,z确定的线条,其中对指定属性PropertyName设置为PropertyValue,其他没有指定属性用缺省值。属性LineStyle和Marker参见命令plot。 line('PropertyName',PropertyValue,…)对属性用相应的输入参数来设置而画出线条。这是命令line的低级使用形式,此时不接受矩阵...
image(x,y,C,'PropertyName',PropertyValue,…) 该形式为指定属性名/属性值的高级使用形式,在执行该命令之前,先执行命令newplot。 image('PropertyName',PropertyValue,…) 该形式为低级使用形式,它只接受属性名/属性值的输入。 handle = image(…) 返回刚生成的图片对象的句柄。用户可以从上面的任何形式的调用...
% The next step is to make a full RGB-image for each image, % by looking up the corresponding rows of the gray and hot colormaps. % % An RGB-image is a 3D-matrix. % It has three "colour slabs" that are joined up along the third dimension. ...
