Despite reading on-line and other documentation I'm not getting the appearance as I want. Here is the script: --- set datafile missing "NA" set xdata time set timefmt "%Y-%m-%d" set format x "%d-%m-%Y" set nokey set xtics rotate font "palatino,11" set xlabel "Date" font "palatine,11" offset -3 set ylabel "Precipitation (in)" font "palatino,13" set title "Daily Precipitation 2008-2010: CC-OR-8" set size ratio -2 plot "cocorahs.dat" u 1:($2) w boxes --- Three issues I've not resolved: 1. I cannot move the xlabel down from the rotated xtic labels 2. The typeface does not change to palatine (and I cannot find a list of the PostScript typefaces supported by gnuplot). 3. I've not seen where to specify a line color of -1 (black) for the boxes. Pointers appreciated. Rich |

I just ask because the other two times you wrote "palatin_o_"? As to that list of supported font --- there isn't one, and there really can't be. gnuplot doesn't "support" PostScript fonts. It just passes what you told it into the PostScript file. The instance that needs to support those fonts is your PostScript interpreter. > 3.

If you don't like that, or want some other linetype in black, use the 'linecolor' option. |

Hans-Bernhard, I don't know if it qualifies as 'exhaustive' but I tried -0.5, -1. -5, and -3 as offsets. What I mean by down from the xtic labels is lower than the label text itself (dates, rotated 90 degrees). > Sure "palatin_e_" isn't a typo? I just ask because the other two times you > wrote "palatin_o_"? Yep. It's a typo. And, apparently, palatino is not recognized as a typeface. It's what I use in LaTeX/LyX. > As to that list of supported font --- there isn't one, and there really can't > be. gnuplot doesn't "support" PostScript fonts.

Well, ghostscript seems to have no issues with palatino in other applications. Where do you suggest I look to learn what typefaces will work locally with gnuplot? > -1 is not a line color.

Seems you missed the meaning of the text in "help set xlabel" about the actual contents of the <offset> argument. Note how it speaks of 'x,y'? What you were looking for is set xlabel 'my text' offset 0, -5 >> Sure "palatin_e_" isn't a typo? I just ask because the other two times >> you wrote "palatin_o_"? > Yep. It's a typo.

Note that LaTeX has an entire world of font specification methods all its own. None of that automatically works for gnuplot, which follows a pretty simple scheme: you give it a string, and it'll put that into the outputfile. For the case at hand, I'd suggest adjusting the capitalization: "Palatino" >> As to that list of supported font --- there isn't one, and there >> really can't be. gnuplot doesn't "support" PostScript fonts.

Blank space with error messages in the virtual terminal that the font cannot be found. > I'd suggest adjusting the capitalization: > > "Palatino" Makes sense. I'll try that. Thank you again, Rich |

Except, when I go to export the grphic and 'set terminal png' there's an error message that gp cannot find "Arial" (probably because I don't have that installed) and it defaults to some non-scalable typeface. I have quite a few Type1, TrueType, and Bitstream fonts installed here. I'm sure there's a name that gp will recognize and accept if I can find the time to go through all of 'em. Rich |

You're silently assuming that font selection must somehow be the same for all terminals. It's not. > I have quite a few Type1, TrueType, and Bitstream fonts installed here. The problem with that idea is that you assume that there is a single, well-defined meaning to "installing" a font. There isn't. > I'm sure there's a name that gp will recognize What you're still not getting is that gnuplot itself recognizes _no_ fonts at all. It's your output system (TeX, PostScript, freetype, cairo, whatever) that does that. So every driver will usually have a different set of fonts. |

What I don't know is how to identify the typefaces available to me under the different terminal types supported by gnuplot. I care less how it looks on the x11 terminal than what it looks like when exported to .png or .ps. Is there documentation that tells me how to find what the terminals support on my linux system? Thanks, Rich |

In partial answer to my question: I set the terminal to postscript, then to png and ran 'test' for each. The results are not what I expected. "test.ps" has no color at all; strictly black-and-white. "test.png" is worse: it's rotated 90 degrees counterclockwise and filled with a gray background. None of the sample text is visible. "test.jpg" shows full color and notes that it will rotate only truetype fonts. So, I guess I get a TT font name it recognizes and output to .jpg rather than to .png. Rich |

On page 206 (listing 11.3) is this example: set t png font FreeSans 11 set t png font "/usr/share/fonts/truetype/FreeSans.ttf, 11" In my script I tried both ways; for example, set t "Daily Precipitation 2008-2010: CC-OR-8" font "/usr/share/fonts/TrueType/verdanab, 15" yet when setting the terminal they both produce the same result: gnuplot> set terminal jpeg Terminal type set to 'jpeg' Could not find/open font when opening font "arial", using internal non-scalable font Options are 'nocrop medium ' BTW, I have the arial fonts installed in that same directory. What am I still missing? Rich |
