DPlot

Dave,

Where can I download the new version of the DLL interface DPLOTLIB.DLL (v.2.1.0.6) referred to in the DPlot v. 2.1.4.0 release notes ?
The one found in the downloads area is v. 2.1.0.5 from Sept. 27.

Dave,

No need to react. I copied the exe-file from a colleague's installation.
Everything now works OK.

Dave,

Sorry for this late reply. I have installed the full v.2.1.3.2, previously received via the update facility. After re-installing again there is no trace of the WEBUPDATESVC.EXE file in the install directory, which explains why nothing happens when I click the update button, but I can't figure ...

Dave,

Actually this is probably not a bug per se, but for odd
(Windows XP) reasons, I had to un-install and re-install DPLOT,
and somewhat to my surprise the convenient Web update
facility no longer works.
Any clues - Registry settings, or .. ?

Hi Dave,
When I run Dplot 'manually' I can control the 'Minor/grid tick divisions' on the X- & Y-axes via the 'Options->Extents...'. menu. The result of my choices are reflected in the associated .grf-file under the tag 'MinorGridLines'. Now I want to control DPlot from a Fortran90 program using the ...

Thanks for your prompt reply.

I don't think I would ever use 'Points', but I would like to have the 'mm' option available, since this is my preferred unit.
Not a big deal though, but more of the 'nice to have' than 'need to have'
type of wish.

Dave,

Thanks for the 2.102 release.
Being a European I appreciate the possibility to choose metric length units,
but when selecting 'mm' in the 'Options->General' menu, the unit comes out as 'cm' in the 'Specify Plot Size' box. Similarly, when choosing 'Points', the unit comes out as 'Inch ...

I'm plotting some functions using the 'Generate -> Y=f(X)' option.
For some odd reason the following expression returns identically
zero for x in [0;3], dX=0.01

f(x) = 5.*(cosh(4.*x)+4.*cosh(2.*x)+3.)

If I build up the expression term by term, everything works fine,
until I enclose in parentheses ...

Dave,

Take care and take your time to recover - judging from the
X-Ray posted it looks like a collar-bone fracture.
I know exactly how it feels (from too much skiing) ,
especially the pain you have to sustain when you have to
drive 800+ km with a bone fracture like yours.

This is *not* a big ...

Dave,

I exit by clicking the upper right cross in the editor window,
not via File->Exit.

I have just checked that if I use File->Exit instead, then the
DPMAX.EXE disappears from the Task Manager list.

Dave,

I have experienced problems with the Macro facility in DPlot.
I am using the current ver. 1.9.8.1 under Win2k/SP4.

Here is what happens : I open the Macro Editor (File->Macro),
choose an existing macro for Edit/Create, which brings up
DPMAC.EXE in the Task Manager's process list.
Then I edit ...

I have run into problems when attempting to change fonts in the most recent release, 1.9.1.7 beta.
Selecting 'Fonts>>' in e.g. Legend/Labels results in the error message :

'Error in GetPrinterDC for default printer'

followed by a message that no fonts are installed.

Reverting back to ver. 1.9.1 ...

Dave,

Thanks for the prompt response and the new 1.908 rel.

I am still finding problems with the EqualIntervals command though.

Eg. generate y(x) = 0.12+0.26*sin(26*x) (x in radians)
within x = 3.1 to 3.5 with a spacing of dx=0.002, corresponding
to a total of 201 points.

Now use EqualIntervals ...

I am using EqualIntervals (Cubic Spline interpolation) simply to
increase the number of data points so as to produce smoother curves.
For a long time I have noticed that very often the last data point
is not regenerated in the interpolation process. This can be easily
fixed by cutting and pasting ...

I have been using AddCurves in MACROs for a while, which is very
convenient, since one can do simple operations on existing
curves 'unattended', i.e. without being interrupted.
With the new rel. 1.9, a window pops up whenever I call AddCurves in
my MACRO, waiting for input for a function (e.g. y1+y2 ...
