i plotted a 3d plot with the following code, but with my own measured data:
我使用以下代码绘制了一个3d图，但是使用了我自己的测量数据：
Data = rand(1000, 4); % 4 Channels or more or less
Time = 1:1000;
sData = size(Data);
vSignal = 1:sData(2);
plot3(Time, vSignal(ones(1, sData(1)), :), Data);
view(-150, 60)`
Now I want to fill under the graphes I plotted.But it´s really important for me to be able to plot and fill below multiple graphes! Do I have to use fill3()? I imported my data as a numeric matrix. I tried several ways but I failed. Thanks for help.
现在我想填写我绘制的图表。但是对于我来说，能够在多个图形下方进行绘图和填充是非常重要的！我必须使用fill3（）吗？我将数据导入为数字矩阵。我尝试了几种方法，但我失败了。感谢帮助。

Here is how to use fill3:
以下是如何使用fill3：
for ii = 1:sData(2)
fill3([Time,Time(end),Time(1)],ii*ones(1,size(Time,2)+2),[Data(:,ii);zeros(2,1)],ii*ones(2+size(Time,2),1),'EdgeColor','none');
end
I use the for loop since I create a patch for each plot separately (I call the filled-in area a Patch). For each patch, I need to give its boundaries, and fill3 will fill everything in between. The boundaries are the exact points that you used in plot3, but in addition you need two more points on the x-y plane to close the patch (to make it a polygon). That is the reason I extend the vectors by 2.
我使用for循环，因为我分别为每个绘图创建一个补丁（我将填充区域称为补丁）。对于每个补丁，我需要给出它的边界，fill3将填充它们之间的所有内容。边界是您在plot3中使用的精确点，但另外您需要在x-y平面上再多两个点来关闭贴片（使其成为多边形）。这就是我将向量扩展2的原因。
