[英]Plotting Accelerometer 3 axis value in Matlab
I have two task to do 我有两个任务要做
For first I used the following code: 首先,我使用以下代码:
s=serial('COM10');
fopen(s);
out=fscanf(s);
while(out~=0)
out=fscanf(s);
disp(out);
end
fclose(s);
now in second part i have to plot there data in real time how can i do it ,m new to matlab i tried the following sample code to plot 3 values but didn't worked out. 现在在第二部分中,我必须实时绘制那里的数据,我该怎么做,这是Matlab的新手,我尝试了以下示例代码来绘制3个值,但没有解决。 please help. 请帮忙。
x = -50;
y = 10;
z = 20;
while(1)
plot3(x,y,z);
XLABEL('X Axis');
YLABEL('Y Axis');
ZLABEL('Z Axis');
set(gca, 'XColor', 'r', 'YColor', [0 0.5 0.5], 'ZColor', 'y')
x=x+2;
y=y+2;
z=z+2;
end
Change the code, use plot only once: 更改代码,仅使用一次绘图:
X=[];Y=[];Z=[];
x=0;y=0;z=0;
figure(1);
myplot=plot3(x,y,z);
while(1)
x=x+1;
y=sin(x);
z=cos(x);
X(end+1)=x;
Y(end+1)=y;
Z(end+1)=z;
set(myplot,'Xdata',X,'YData',Y,'ZData',Z);
drawnow limitrate;
end
If the loop run long enough, don't forget to limit X,Y,Z sizes(for example every 1000 samples delete 500) 如果循环运行足够长的时间,请不要忘记限制X,Y,Z的大小(例如,每1000个样本会删除500个)
