plot(rt_time,rt_theta), axis([t_out(1) t_out(length(t_out)) min(y_out) max(y_out)]) gridon rt_i = rt_i + 1; n_test = n_test + 1; pause(dt) end toc So this gives me a realtime plot of the data. The problem is, that if I for example plot for N = 500 then...
the app analysis. I tried with EditField but it displais only the value 1 at the end of the process, whereas I want to display in real-time the value of the variable called k that keeps track of the progress of the for-cycle. Below I attach the code of inter...
end 在上面的程序中,realTimePlot()函数用来实时绘制正弦曲线,每次调用绘制一条新的曲线,并通过drawnow函数将图形显示出来,然后暂停0.1秒等待下一次调用。startBtnCallback()函数用来创建一个Timer对象,定期调用realTimePlot()函数实现实时绘图,而stopBtnCallback()函数用来停止Timer对象的运行。

I'm tryingto plot ultrasound data in realtime in Matlab which is being sent to the computer via RS232. The below code works in batches - i.e. I can click run and Matlab will plot the 6 data points correctly... but...I can not get it work in real time. The graph needs to upd...

serial data & real time plotIf it gets too slow please consider the preallocation of XData and YData, fill it with NaN values and when the loop gets to the end of the preallocated data do something to "reset" it, if your script only runs for a short while you don't have to do it...

1) i start the real time scatter plot and then try to draw a roi on top, it doesnt let me or show it at all 2) i draw the roi first and then start the real time scatter plot, but it then removes my roi so it seems no matter what the case, i cant have both at the same ...
