在 Matlab 中将绘图保存为 PNG [英] Saving a plot as a PNG in Matlab

问题描述

我有一个绘制时间序列的函数，现在我想将其保存为图像，请问如何做到这一点?

I have a function that is plotting a time series, now I want to save this as an image how can this be done please?

function TimeSeriesImages(a, b, c, d, e, f, g, h, i, j, k, l)
x = [a b c d e f g h i j k l];
ts1 = timeseries(x,1:12);
ts1.Name = 'Monthly Count';
ts1.TimeInfo.Units = 'months';
ts1.TimeInfo.Format = 'mmm dd, yy'
ts1.Time=ts1.Time-ts1.Time(1);
plot(ts1)
end

推荐答案

在 Matlab 中保存图形的另一种方法是使用变量处理它们并稍后保存.

Another way of saving figures in Matlab is handle them with variables and saving them later.

例如:

a=bar(...);
b=hist(...);   %some figures
c=plot(...);

saveas(a, 'path	ofileabc1.png','png');
saveas(b, 'path	ofileabc2.png','png');
saveas(c, 'path	ofileabc3.png','png');

来自官方 Matlab 帮助的片段:

---

Fragment from the official Matlab help:

saveas - 使用指定格式保存图形或 Simulink 框图

saveas - Save figure or Simulink block diagram using specified format

语法

saveas(h,'filename.ext') 
saveas(h,'filename','format')

说明

saveas(h,'filename.ext') 将图形或 Simulink 框图保存为文件filename.ext的句柄h.文件的格式由扩展名 ext 决定.有关更多信息，请参阅 Matlab 帮助.

saveas(h,'filename.ext') saves the figure or Simulink block diagram with the handle h to the file filename.ext. The format of the file is determined by the extension, ext. See Matlab help for more.
