DPlot

Excellent - that is perfect.

I really like it that you have exposed internals such as X Y, indepedent variables etc.

It gives you a great flexibility to process the data sets - also it is fast.

A great product - I am sold !

The following is a query because I do not claim that this should work, given that the time stamp is too coarse.

I have a file with data that is sampled faster than a second but the time tag is like

19/10/2011 15:54:50 10
(repeat 8 ) 11,13 etc
19/10/2011 15:54:50 21
19/10/2011 15:54:51 21 ...

Worked as you said - I thought F(x) needed to be included in the syntax - my mistake.

Many thanks,

That should do what I need - excellent. I had not thought of that combination of moves, that is very flexible.

Thank you !

p.s.

Just figured, since x increments by 1, I can differentiate the curve

I will try that once I have the data set here.

One of the things I need to do is to subtract two curves. They are both plotted against time.

I tried F(X,Y1,Y2)

As an example I am trying to subtract

Y1:sin(x)
Y2= 2* sin(x) + 10

I use Generate F(X,(y1-y2)

and get the error message

"too many parameters at X=0."

I tried straight lines and ...

Dear forum,

my name is Boris and I am new to DPlot but very impressed with the ease of use.

There is one task that I would like to do in Dplot and perhaps it is possible,

I have data such like
(x,y)
(1,10)
(2,20)
(3,20)
(4,25)
(5,32)

and would like to produce a sequence where each point in Y is ...
