随着时间变化的Matlab图 [英] Matlab Plot that changes with time

问题描述

我正在尝试绘制随时间变化的图形(可以将其绘制为随风通过时绘制杆的形状，因此我想每秒绘制一次形状).

I am trying to plot a figure that changes with time (think of it as plotting the shape of a pole as the wind passes through it, so I want to plot the shape at every second).

为避免x轴限制频繁变化，我想将其固定为限制(绘制前计算出的最大值和最小值).这是我的代码示例:

To avoid the x axis limit changing frequently I want to fix it to the limits (max and min that I calculate before plotting). Here is a sample of my code:

for i=1:1:numberofrows
    momentvaluesatinstant = momentvalues(i,:);
    figure(1)
    plot(momentvaluesatinstant,momentheader)
    drawnow
    title(sprintf('Moment profile along pile at time 0.2%f',time(i)'))
    xlabel('Moment (kN.m)')
    xlim([momentvalues(rowminmoment) momentvalues(rowmaxmoment)])
    ylabel('Length of pile (m)')
    delay(1);
end

尽管我将x轴的极限值固定为我指定的值，但是该图会根据要绘制的数据不断更改极限值?有什么我想念的吗?

Although I am specifying the limits of the x axis to be fixed to the values I specify, the plot keeps changing the limits depending on the data being plotted? Is there something I am missing?

推荐答案

想通了，需要添加xlim manual
