Gnuplot postscript to file

Now, go back to the postscript data above, you can see "[4 dl 2 dl]" which defines a line pattern to draw dotted, dot-dashed, and dashed lines. For LT1, the pattern is defined as "[4 dl 2 dl]". This gives a solid line of 4 unit length and a space of 2 unit length, so that it becomes a dashed-line. If you need an extra line pattern, edit here to make your own.

The line LTb is used for the border of graph, and LTa is for the zero axes. Their color is black since RGB is "0 0 0". If you want to change those color, edit here. A square figure can be drawn by set size square. However, an EPS file generated with gnuplot is not square but still rectangular, and you get extra margin. Creates a figure directly on the svg file given with fname. This uses Gnuplot terminal svg. Prints the current figure to the given file with name fname.

Only png or eps files are supported by default. I'm not sure what's wrong, so I just copy-and-pasted the whole terminal output. I'm sorry it is so long.. You asked for postscript and it gave you PostScript. Terminals such as this just write the output in the appropriate format, and gnuplot isn't supposed to give a graphical window showing you what it looks like.

Not producing a graphical window is nice for batch jobs or scripting. For example, when writing a paper, I usually write a build script that calls gnuplot to build my plots as. These are then used in my LaTeX file. If you have many plots or important dependencies, this is especially helpful.

I run one script and it builds everything as needed. This ability to be scripted is one reason gnuplot is so useful. You may want to consider using "encapsulated PostScript". EPS is the same output as postscript , but with a bounding box around it it also has a different file header, but is otherwise the same format.

What you would want depends on whatever you are using your PostScript for. You can also put terminal options on the same line as the set terminal :. Asked 11 years, 4 months ago.

You can query Ghostscript about all its output "devices" like so: gs -h Now limit the query to only lines containing PNG-related devices: gs -h grep png You'll see there is a pngalpha output device. Next, query convert about its full list of delegates: convert -list delegate You'll see a few dozen commands which convert uses behind your back in order to get its job done.

Let's see, what commands it uses for PNG input or output handling: convert -list delegate grep -i png You'll likely discover gs Kurt Pfeifle Kurt Pfeifle Pipitas already nicely explained why this is happening. Hence, you should try something like: convert -density -alpha off input. Jan-Philip Gehrcke Dr.
