Please have a look on the two pictures, especially on the x-scale.
Both are done with the same settings:

upper picture:
Code:
      CALL winop@("%pl[x_min=0.,x_max=5.]")
      CALL winop@("%pl[dx=0.5,dy=0.1]")

lower picture:
Code:
      CALL winop@("%pl[x_min=0.,x_max=3.0]")
      CALL winop@("%pl[dx=0.5,dy=0.1]")

Why the upper x-scale has a 0.45-step and not a 0.5-step ???

I agree that does not look right. Is it possible to send me the code and the data?

I am assuming that you are using w recent version of ClearWin+.

I'm using FTN95 V8.4 licensed.
I've tried to send the code of the subroutine (180 lines) with the [code]-markers, but this failed.
Exists a line limit?
How the code can be transferred?

FK,

Try https://wetransfer.com/, or sign up to DropBox. WeTransfer is simple and quick. There's a fairly short limit on the length of a post in the Forum.

we've never had a solution to this longstandng problem of post max length have we.
A solution seems to inolve an administratr just changing a parameter, can't this be done easily and if not why ?

Eddie,
your link above has an erroneous full stop at the end !

Correct link is: https://wetransfer.com/

Looking at the Konowledge Base for thee service it seems that any uploaded files are only kept for 7 days with the free service.
To me personally that would seem inappropriately short for a forum like this and I'd suggest Dropbox or similar is a better option to 'kep the post going' for moe than a week (apart from those who might have aleady downloaded the file) of course.

And of course the good 'ol tried and trusted (if frustrating) multi-posted listing
(it would be useful to know what the current limit is), say for code listing žs of up to 4 comments max (based on experience I don't think anyone has ever exceeded that)

.... or max 10 lines in Paul's case Wink (this is a joke)

to answer FKGER's question, it's all in the algorithm. !

The native %pl scales algorithms have been notoriously finicky (sensitive).
Some strange things do happen.

You're lucky in that your datasets start with 0.0.

Try the following for example deleting the first 2 data points from your dataset and report back here what you get for the 2 cases you have reported above.

Are your plot windows re-sizeable ? If so, what happens when you arbitrarily resize with the mouse drag ?

If you feel particularly adventurous, and brave, and have the time, try using log scales and see what happens. The best description I have is that it's a bit like playing the Casino at Monte-Salford Wink
