DPlot

Maybe it's me, but the access to the "Dot Graph Format" and "Dot Graph Options" dialog seems obscure. DPlot Help implies that "Dot Graph Format" should be on the "Options menu", but it's not and the only way I seem to be able to access it is by right-clicking on a box-and-whisker plot. What am I ...

Dave,

That will work. Thanks for the quick reply.

Dave,

Here's a non DPlot (off-topic) suggestion for quickly obtaining and DPlotting free historical foreign exchange-rate data that your users might like - similar to the previous one for free stock quotes that appears in your FAQ.

Dave,

Dplot continues to be most useful.

I have an X/Y graph with two lines that cross at a mid-X value (Line 1 values exceed Line 2 values at X < mid-X and Line 2 values exceed Line 1 values at X > mid-X)

It would be most useful to fill one color or fill between Line 1 and 2 where Line 1 > Line ...

Thanks, again, David

I should have known...

David,

Starting with a pressure waveform in psi with 30 ms of data recorded at 1 MHz (30,000 data points). I lable the X axis as microseconds and Y axis as psi.

When I do an FFT of this signal, it produces a FFT plot of magnitudes from 0 to 500 KHz with one point (magnitude) about every 30 Hz ( n ...

Dave,

Thanks for the solution and quick reply. Much appreciated.

I'm trying to estimate the roll off in dB for the bandpass filter by generating a 100 Hz sine wave and then setting the bandpass low cutoff just above 100Hz (150 Hz) and hi cut off at some 10s of kHz. But every time I try to bandpass filter the generated sine wave, DPlot crashes.

Details, I ...
