รวมเวปที่ใช้สำหรับ gnuplot / websites for gnuplot info

Gnuplot ใช้เพื่อพล็อตข้อมูลออกมาในรูปแบบกราฟต่างๆ ใช้ได้กับหลากหลายแพลตฟอร์ม ที่สำคัญคือมันฟรี จริงๆแล้วมันมีความสามารถหลากหลาย แต่ติดที่การทำงานต้องใช้ command line ทำให้สำหรับคนที่ไม่คุ้นเคยกับการใช้ command line อาจรวมไปถึงพวกยูนิกซ์คอมมาน ก็จะงงๆเล็กน้อย แต่จริงๆแล้วมันไม่ยากเลย

ที่สำคัญไฟล์ที่พล็อตออกจากเจ้า คนุปพล็อต ก็หลากหลาย ปกติเราจะใช้เอาต์พุตแบบ .eps ซึ่งทำงานกับ LaTeX ได้ดี และยังเป็น vector based ทำให้เราสามารถแก้ไขโดยใช้โปรแกรมอื่นๆได้อีก (ไม่ได้แนะนำให้แก้ข้อมูลให้ได้ตามใจนะจ๊ะ) เช่นพวก Illustrator เป็นต้น

Gnuplot is a portable command-line driven graphing utility for Linux, OS/2, MS Windows, OSX, VMS, and many other platforms. Gnuplot supports many types of plots in either 2D and 3D. It can draw using lines, points, boxes, contours, vector fields, surfaces, and various associated text. It also supports various specialized plot types.

Gnuplot supports many different types of output: interactive screen terminals (with mouse and hotkey input), direct output to pen plotters or modern printers, and output to many file formats (eps, fig, jpeg, LaTeX, metafont, pbm, pdf, png, postscript, svg, ...).

Personally, I only use Gnuplot for 2D plot. Working with LaTeX, I found Gnuplot is easy and flexible enough for visualizing a general info graph for publishing in scientific article.

For those who just starts using `Gnuplot', I found this website is the best for starting and running for the very first time.

For in depth information and demos, the main download site is great.
http://gnuplot.sourceforge.net/

You can access just the manual here: http://www.gnuplot.info/docs/gnuplot.html
Both of them are often updated.













This website collects `not so frequently asked questions' which I found useful for many cases, though it seems lacking of maintenance by now.

เขียนทีสิส ดราฟแรกเสร็จแล้ว

ความรู้สึกตอนที่เขียนเสร็จประมาณว่า "เอาละ ได้แล้วแหละ"
เพราะมันเป็นตอนตีสี่...

ตอนนี้เลยมานั่งรีวิวไปเรื่อยๆระหว่างรอรีวิวจากอาจารย์
เฮ้อ ศึกนี้ยาวนานนัก และยังไม่จบง่ายๆ สู้ๆๆๆๆๆๆๆ

Where 어디에 - Nappeun Namja ^_^

내게 찾아온
내게 찾아온
내게 찾아왔던
사랑은 어디에

돌아올꺼야
돌아올꺼 야
말도 못할만큼
널 사랑했는데

서롤 사랑이라 불러주던 우리
사랑 말곤 더는 할게 없던 우리
수천번도 넘게 맹세 했던 우리
어디에

나의 가장 예쁜날들 속에 우린
어디에

행복했는데
좋았었 는데
말도 못할만큼
널 사랑했는데

서롤 사랑이라 불러주던 우리
사랑 말곤 더는 할게 없던 우리
수천번도 넘게 맹세 했던
너무 사랑했던 기억이

저 하늘도 갈라 놓을 수 없던 너는
끝내 이별 앞에 뺏겨버린 너는
안녕이란 말로 숨어버린 너는
어디에

내가 가장 사랑했던 날의 너는
어디에

Where is the love
that came to me
that came to me
that'd come to me

You would come back to me
You would come back to me
I loved you
as much as I could not even say a word.

Where are We
We who would say each other 'love'
We who had nothing but to love
We who sweared more than thousand times

Where are we in which
my most beautiful days are

I was happy
I liked it
I loved you
as much as I could not even say a word.

We who would say each other 'love'
who had nothing but to love
who sweared more than thousand times
The memory that I loved so much

Where are you that even God could not break
that I've lost in front of break up
that hid with a word "good bye"
Where are you"
