颜色图是由值组成的矩阵，这些值用于定义诸如曲面、图像以及补片之类的图形对象的颜色。MATLAB 通过将数据值映射到颜色图中的颜色来绘制这些对象。Matlab中预设了数十种不同的colormap颜色图，如图：A colormap is a matrix of values that define the colors for graphics objects such as surface, image, and patc...
matrixplot(scale_re,'XVarNames',XVarNames,'YVarNames',XVarNames,'TextColor',[0.6,0.6,0.6],'ColorBar','on'); matrixplot functionmatrixplot(data,varargin)% 根据实值矩阵绘制色块图,用丰富的颜色和形状形象的展示矩阵元素值的大小。%% matrixplot(data) 绘制矩阵色块图,data为实值矩阵,每一个元素对...
copper: A colormap that transitions from dark to light copper tones. You can apply any of these colormaps to your plot by passing their name as an argument to thecolormapfunction: % Create a matrixM=magic(7);% Create a 2D plot using the 'jet' colormapimagesc(M);colormap('jet');co...
特别提示:此处TheColor仅为作图方便,可以替换为自己的配色。 3. 散点矩阵图绘制 使用‘plotmatrix’命令,绘制未经美化的散点矩阵图。 % S - 散点图的图形线条对象% AX - 每个子坐标区的坐标区对象% BigAx - 容纳子坐标区的主坐标区的坐标区对象% H - 直方图的直方图对象% HAx - 不可见的直方图坐标区的...

Create a surface plot of the peaks function and specify a colormap. Get mesh(peaks) colormap(autumn(5)) Return the three-column matrix of values that define the colors used in the plot. Each row is an RGB triplet color value that specifies one color of the colormap. Get cmap = ...
The contour3 function is used to draw a three-dimensional contour plot of a matrix, and its usage is basically the same as the contour function. 【例5】绘制函数图片的等高线图形,并使用cool颜色图。 [Example 5] Draw the contour graph of the funct...
语句colormap(M)将矩阵M作为当前图形窗口所用的颜色映象。例如,colormap(cool)装入了一个有64个输入项的cool颜色映象。colormap default装入了缺省的颜色映象(hsv)。 函数plot、plot3、contour和contour3不使用颜色映象,它们使用列在plot颜色和线形表中的颜色。而大多数其它绘图函数,比如mesh、surf、fill、pcolor和它...
plot(X,Y) plots vector Y versus vector X. If X or Y is a matrix, then the vector is plotted versus the rows or columns of the matrix, whichever line up. If X is a scalar and Y is a vector, disconnected line objects are created and plotted as discrete points vertically at ...
% xi - x coordenates for zi matrix % yi - y coordenates for zi matrix % zi - unfiltered data densities at (xi,yi) % zif - filtered data densities at (xi,yi) % [c,h] = contour matrix C as described in % CONTOURC and a handle H to a contourgroup object ...
