怎样使用波形图显示随机数

[普林斯]

各位大侠：

      小弟刚刚开始学习Labview，最近遇到一个问题想请教一下各位：我要编一个小程序，随机生成浮点数并用波形图显示，直接将随机数Vi与波形图显示控件连接的话，程序报错：说数据类型不一样。使用右键创建显示控件的话只能出现数值显示控件，这种情况怎么解决，还请给为赐教。小弟不胜感激！

Hi,

You may use a Chart instead.

A graph takes in array data. If Graph is a must, you need to add shift-register and build array functions.

我创建chart之后显示的是数值属性的显示控件，而不是图形属性显示控件，这样做哪些相应的调整那

So, you need a Graph? or a Chart?

Thanks for you help.

Ether chart or graph is ok,the question is I can't find the suitable chart that can be connect to  stochastic number vi.

Hi,

I see that you are trying to wire/ connect a random number output to a numeric constant?

What you can do is... go to front panel, add a Chart/ Graph. Then, go to block diagram for the necessary wiring work.
