Flexible display

[alex.]

The are 2 kinds of requirments

1) only select 1 channel from DAQ, display 2 waves from that channel.

2) or select 4 channels from DAQs, display 4 waves from each channel on same screen.

May I know how to do it?

2) or select 4 channels from DAQs, display 4 waves from each channel on same screen.

Configure all four channels in the same Task and use a single DAQ read function ( In DAQmx Read, select a suitable type/instance) and display data on a common Graph/chart

1) only select 1 channel from DAQ, display 2 waves from that channel.

And how do you plan to read 2 waves/signals on a single DAQ channel?? are you externally multiplexing 2 signals onto a single channel??

I mean sometime I need to display 1 graph, while other time I need to display 4 graph, how to change dynamically?

Hi turbot-

What you want to do is accomplished with the 'Visible' property for either the entire indicator or individual plots.

If you want 4 different waveform graph indicators, [right-click on each graph]>>Create>>Property Node>>Visible.

If you want 4 plots on the same gridspace, [right-click on the graph]>>Create>>Property Node>>Plot>>Visible for each one.  And you'll need to utilize the Active Plot property to distinguish which one you're making visible/invisible each time.

Hope this helps!

Any other ways, do not like using visible

Use a Tab Control to contain your displays and switch between the tabs when required.
