graph & chart history length

Solved!

I was wondering why "chart" has got a "chart history length" property for the length of the displayed data, 

but "graph" doesn't have such a "history length" property. 

 

Why!?

Hi Cashany,

 

maybe because charts have a history and graphs don't?

So, how do graphs work without a history (memory)?

Hi Cashany,

 

you have to make your own buffers then.

 

Well, there are examples coming with LabVIEW. There ARE examples showing how to use charts and graphs!

All right, I'll see the examples and try to understand how graphs & charts exactly work.

Hi Cashany,

 

"how graphs & charts exactly work": charts collect data in their history buffer and plot the history, while graphs only plot the data you provide them...
