The following file contains 9 points of data, dense in x-direction and connected by a line. The first line is printed on all printers, available to me, as well as displayed by the Abobe Acrobat in with large noise generated. In the second line the intrinsic noise in the data is amplified 10 times but the line is printed correctly. Expansion the distance in x-direction 100 times (Line 3) makes the line look correctly. The bahavior if the same in all PostScript devices.

Is it my mistake ? The file seems to be crystal clear.

Leonid,

The file is clear and it prints correctly (i.e. what you ask for is done). However, you forgot to set the scales, therefore the default
applies: 25.4/72 = 0.35 mm.
Now you ask for hundredth of this...

No wonder that all your points look like on top of each other, especially your blue line.
You may even bump into device resolution problems.

Set the scales and it'll be fine.

Miklos
