plt.savefig('plot123.png') 保存图片的格式是根据 后缀名来判断的 两个参数共同决定图片的像素大小: figure size mpl.rcParams['figure.figsize'] dpi mpl.rcParams['savefig.dpi'] 例如8x6 inches figure,100dpi的图片,最终像素是 800x600 当图片显示在屏幕上时,长度单位是被忽略的,单纯显示像素 当打印或在...
set(p, {'XData'}, mat2cell(new_data, ones(1,3),3)); See alsomat2cell, in this case I use it to reshapenew_datato a 3x1 cell array each containing a 1x3 row fromnew_data. (byMax Chandler、mikkola) 參考文件 How can you set the XData of a Matlab line graph plot with a 2...
Now I want to do the same thing in python. I already know how to plot a 2d matrix (numpy array): from matplotlib.pyplot import imshow import numpy as np data = np.random.random((10,10)) imshow(np.asarray(img)) but I don't know how to add a colorbar to it. ...
选择数据点时,您希望将时间作为polarplot中的第三个值,为此,您可以将时间(变量t)添加到polarplot的ZData属性中。 要做到这一点,您需要使用polarplot轴的处理程序,即hax = polarplot(phi, r, '-sb');,这样您就可以将时间作为ZData:hax.ZData = t;。完成此操作后,myfunction中的变量pos的长度将由2变为3,因...
I use for environment plot points (but these are discrete points, not a region). If I use surf(data), it will have a 3D plot:I can rotate this 3D plot and view above, just like:This image is what I want plot on 2D plane.
