how to save graphs running continously

[MindPower]

Dear All,

     Can anyone help me in saving the graphs running continously for hours in any format. I am able to catch the graph via print screen key from keyboard for only one instant,however, my need is to save the whole graph starting to end which gets updated continously.

Thanks & Regards

There are a number of ways to save data. Look at the File I/O palatte and do a search of the shipping examples. On the File I/O palatte are Write to Spreadsheet File, Write to Measurement File, Write Text File, Write Binary File, and the whole TDM Streaming sub-palette.

You can programmatically get an image of the graph using an invoke node with method "get image". Now you just need to generate sequential filenames and automaticall save each image, e.g. using "write PNG file"

What is the purpose? Are you trying to turn this thi into a movie? A graph image is pretty useless for record keeping, because it is limited by the screen resolution and the data is no longer mathematically acessible.For record keeping, you should stream the raw data to disk.

Hi ,

Thanks for your reply.

Actually our need to save the graphical pattern comes from the demand from customer as they feel that data files other than graphical patterns are manipulated which is not acceptable and which is actually never done but customer is customer and we have to respect his views.

Thanks & regards !
