Out of curiosity, I checked to see what we do in qsas. We "roll our own" linestyles using plstyl to offer our users 5 linestyles: solid, dashed, dash-dot, dotted, and dash-dot-dot-dot and give them a parameter to scale (stretch) the pattern. I attach a sampler, which uses a factor of 2 for the stretch factor. These are pretty similar to your new styles 1,3 ,5 ,2 and 8 although I think our "dots" are shorter than yours. I'm inclined to agree that the old plplot linestyles are less than optimal. I don't have strong views on how plplot might move toward better default line styles. Since we do our own anyway, your Option 1 wouldn't affect us at all. But while some users are bound to rejoice and say "at last" others will be annoyed that they don't get the same plot tomorrow that they did yesterday because someone changed something on them. I suspect I am guilty of complaining on this list about the odd change - though far less than changes imposed by the likes of IDL or Qt. I can recall an occasion when IDL, in a minor upgrade, swapped 'round the return of 0 or 1 from a routine to indicate success/failure without any mention of it anywhere in the release notes. We switched to pgplot soon thereafter! :-) Best wishes Steve -- +-------------------------------------------------------------------+ Professor Steven J Schwartz Phone: +44-(0)20-7594-7660 Head, Space & Atmospheric Physics Fax: +44-(0)20-7594-7772 The Blackett Laboratory E-mail: s.schwa...@imperial.ac.uk Imperial College London Office: Huxley 6M67A London SW7 2AZ, U.K. Web: www.sp.ph.ic.ac.uk/~sjs +-------------------------------------------------------------------+

It contains a definitive record of application performance, security threats, fraudulent activity, and more. Splunk takes this data and makes sense of it. IT sense.
