You would want to use waveform chart and not graph. Post your current code for more help.

Why on earth would you say that you can't use a graph?

Turn on context help. Go to the block diagram and move the mouse over the graph indicator. The help window shows the various inputs to a graph - ie a 1D waveform array.

Hit post too soon.

To append new data to old, you can use a shift register or create a limited length buffer to keep the data from growing too large. Similar to the example called XY Chart.

Hi,

To support with Dennie, here is the vi. Have a look at this, probably this might help you to carry on with your work.

Hi,

Thanks for your response.

This vi has almost resolved my problem except that i want graph's time axis should move ahead & backward data deleted as new data comes like 10-20 seconds data shown in graph & then if 20-30 sec data comes it should automatically delete 10-20 sec graph data & should show 20-30 seconds graph and similarly it is going on.

Can you suggest how to do it?

This is just example and one of my old VI. It resembles to your project.

Or

try and make a search on forum as "multiple plot" and see where does it end.

Hope this may helps you.

Hi

Check this out probably this is the one u asked i think....

No,  i want graph should move like a chart with every second updation.

Why i choosen graph then because i want a horizontal cusror which is not available in chart.

So i want this type of graph with horizontal cursor.
