gap in the curves

I need to insert a gap in a curve because I have missing data in a certain period of time. I tried with the command "Truncate X", but it didn't appear suitable. I tried to change date format, but the result was bad anyhow. Need I to make different curves?

You can insert a point in the gap with a Y value well outside of the limits you're interested in, then use the Amplitude Limits command on the Options menu to set the limits to values inside whatever value you assigned that point.

For more information on the command see http://www.dplot.com/help/index.htm?helpid_ycutoff.htm

That's right.

Let me to make a suggestion: should be nice to choice between curves in order to create a gap (especially if you have multiple axes).

Thank you!

I'm not sure I understand. All you need to do is set the Amplitude Limits values to magnitudes that are well outside the extents of any curve on your plot. Multiple Axes or not, it works the same way for all curves: if a point is outside those limits then there will be a gap there.

BTW the e-mail address you supplied when signing up isn't working. Since you elected to receive reply notices when signing up, I'm getting e-mail failure notices for your address. No big deal for me, but if you expect to be notified of replies then you'll need to change your e-mail address in your Profile. You can opt to not show your e-mail address in the member list, so there's no danger in supplying a legitimate e-mail address.

My suggestion came from the fact that I lost a second curve enabling the Amplitude limits. But that curve (Y2) was in no symbol style with few value Y2>0 separated by several Y2=0: so the line linking values disappeared. If necessary I can send you the graph.

Regarding the BTW problem, sorry ... what does mean BTW?

Thank you.

Yes, please send me the file at your convenience.

BTW="By the way". I sometimes forget that we have a global audience.

I got your file, thanks. But I'm not sure I understand what you're wanting to do. Your initial post mentioned "gaps", so I assumed you actually wanted a gap to show between good values if you had an intermediate "bad" value. If that isn't the case - that is, you want to show line segments between all of your good values, then instead of the Amplitude Limits command you should use Edit>Clip Y.

The difference between the two commands is that Amplitude Limits keeps all of your data (but doesn't draw line segments between points with an intermediate value outside those limits). Clip Y tosses out data points outside the specified range.

If that doesn't answer your question please let me know.
