How to change the display in the waveform graph to enable higher frequency displays.

[roopa 649]

I am working with waveforms of very high frequencies upto 2MHz. When the frequency of the waveform is increased above 500Hz, the display in the waveform graph goes blank.
Please help me.
Thanks

Roopa,

Please be a little more elaborative in your question. I can't figure out what you are asking.

If possible, attach your code as well.

Dear Labviewguru,
Thanks a lot for your response.
The problem had been technical, and it has been solved.
Actually, I didn't specify the number of samples while generating the waveform, so only frequencies upto half the default value (1000) were being displayed.
