colormap(slanCM('rainbow')) 进行颜色修改: % demo1surf(peaks,'EdgeColor','w','EdgeAlpha',.3)% 使用slanCM的彩虹配色colormap(slanCM('rainbow'))% 修饰一下ax=gca;ax.Projection='perspective';ax.LineWidth=1.2;ax.XMinorTick='on';ax.YMinorTick='on';ax.ZMinorTick='on';ax.GridLineStyle=':...
Create a surface plot and set the colormap to winter. Get surf(peaks) colormap winter Set Colormap Back to Default Copy Code Copy Command First, change the colormap for the current figure to summer. Get surf(peaks) colormap summer Now set the colormap back to your system's defau...
Plot a Custom Colormap Create a custom colormap and plot it. Then display a colorbar as a visual reference. r = (0:.1:.9)'; g = r.^1.8; b = r.^2.1; mymap = [r g b]; rgbplot(mymap) holdoncolormap(mymap) colorbar('Ticks',[]) ...
先用imshow或者image把图片显示出来，再用colormap设置图像的颜色；常用的配色有jet、hot、gray等等。用法：colormap xxx1.colormap(map)设置颜色图为矩阵map。如果map中的任何值在区间[0,1]之外，MATLAB返回错误：Colormap must have values in [0,1]。2.colormap('default')将当前的颜色图设置为默...

This produces different results from the default colormap-based lighting method. Specify the 'light' object as the last input argument. example surfl(___,s) additionally specifies the direction of the light source. example surfl(X,Y,Z,s,k) additionally specifies the reflectance constant. ...
plot函数代表不同颜色的标示符一共有八种：y：黄色；k：黑色；w：白色；b：蓝色；g：绿色**；r：红色；c：亮青色；m：锰紫色；二维绘图函数
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 )。 1. 2. 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...
ax.Color = 'blue'; % 设置绘图区域颜色 图形函数会在绘图时自动创建坐标区,但是需要在同一个figure中绘制多个图像时,需要指定axes。 0.3 plot plot(x) % 横坐标为x的数据个数,纵坐标为x的折线图 plot(x,y) % 横坐标为x,纵坐标为y的折线图
