Thanks pilnet101 . Basically it increases the line length by 2 every line and memorizes the line. Then at maximum length, the loop starts to decrement, rather than increment and only prints the lines memorized in the increment phase.
With regards to the setting of the quotient q and the line n where the maximum line length occurs, and using the name m for maximum line length rather than l which is easily confused with the number 1), perhaps this is a bit clearer:

The histogram scale is logaritmic, to avoid very short bars for smaller files or very long bars for bigger files.

I know that when using 'while (<FILE>) {}', Perl reads only one line of the file at one time, and store it in '$_'.
Can I change some parameters so that 'while (<>) {}' can read more than one lines, like 2 or 5 lines at one time?
Thanks for the help! (1 Reply)

xsetdashes
XSetDashes() XSetDashes()
Name
XSetDashes - set a pattern of line dashes in a graphics context.
Synopsis
XSetDashes(display, gc, dash_offset, dash_list, n)
Display *display;
GC gc;
int dash_offset;
char dash_list[];
int n;
Arguments
display Specifies a connection to an X server; returned from XOpenDisplay().
gc Specifies the graphics context.
dash_offset
Specifies the phase of the pattern for the dashed line style.
dash_list Specifies the dash list for the dashed line style. An odd-length list is equivalent to the same list concatenated with itself to
produce an even-length list.
n Specifies the length of the dash list argument.
Description
XSetDashes() sets the dashes component of a GC. The initial and alternating elements of the dash_list argument are the dashes, the others
are the gaps. All of the elements must be non-zero, with lengths measured in pixels. The dash_offset argument defines the phase of the
pattern, specifying how many pixels into the dash_list the pattern should actually begin in the line drawn by the request.
n specifies the length of dash_list. An odd value for n is interpreted as specifying the dash_list concatenated with itself to produce
twice as long a list.
Ideally, a dash length is measured along the slope of the line, but server implementors are only required to match this ideal for horizon-
tal and vertical lines. Failing the ideal semantics, it is suggested that the length be measured along the major axis of the line. The
major axis is defined as the x axis for lines drawn at an angle of between -45 and +45 degrees or between 315 and 225 degrees from the x
axis. For all other lines, the major axis is the y axis.
See Volume One, Chapter 5, The Graphics Context, for further information.
