做曲线时的坐标问题

[ThomasYoung]

X值是往复的，就是在最小值和最大值之间往复循环，Y值在某一个值附近微小波动，这样做出来的XY-Graph曲线是许多条线重叠在一起，很不好看，如何解决？是不是换一种坐标系，比如极坐标之类？

希望有例子（LabView 7.1），谢谢！

Since the X values are of 往复, what about showing the data as Histogram?

[ThomasYoung]

在哪里设置？

PS：ian fung，你是不是双休日不回答问题？

Look for Histogram in LabVIEW examples finder.

Answer for PS: Basically, Yes 🙂 (I was out of town)

[ThomasYoung]

我还是没明白！

我是要作旋转轴的角位移—角速度曲线，而轴是先正转在反转的，匀速。

如果X轴是360Degree的话, 可以以Polar Plot 来实现... 每360度刷新.

PS: 如果我没能理解您的问题, 非常抱歉! 看来我对技术术语的理解还不够 😉

yq_LabVIEW 或许能更好地为您解答!

可是X不是360以内

[ian_fung]

X的范围是多少? 您想要表示的图形是怎么样的? 需要包括往复的XY值吗? 还是正旋转后刷新?

[ThomasYoung]

X大概是（-5000，5000）度，要记录所有值（包括往复的XY值），图形把所有数据表示清晰就行。

[ian_fung]

So, does that means -5000 ~ 0 is one direction and 0 ~ 5000 is the other?

If so, you should be able to plot it all in one graph continuously, aren't you? Sorry but I am still not able to figure out your real problem...

Is it problem on X or Y values?
