This reverts commit fbc17e7df9.

Holger Vogt 20d5919e59 Terminal setting to X11 fails in macOS, and is not required 
on Linux.
Setting terminal here is redundant, so remove this setting.

Brian Taylor b774d03162 Change the y-axis direction for a 2d Cider gnuplot. The device surface is at the top and downwards is into the material, which is the normal presentation. Note that the x/y mesh commands in a Cider model also affect the orientation. 2022-02-17 15:45:28 +01:00
Brian Taylor 38848259e4 With the ngspice gnuplot command, enable x/y contour plots for 2d Cider save file data. Usage: gnuplot <file> xycontour <expr>. xycontour is a new flag which is ignored if the plot data is not from 2d Cider. For contours, only a single plotarg <expr> is allowed. With <expr1> vs <expr2>, only <expr1> is plotted and <expr2> is ignored. 2021-10-30 13:21:32 +02:00

Holger Vogt 1398ee7aa0 set the proper preprocessor flag __MINGW32__ 2020-03-15 08:51:17 +01:00
Holger Vogt e53632c368 When plotting arrays of curves, plot lines only in the direction 
of (in absolute terms) growing x values.
Example: MOS output characteristics.
In the rare case of plotting versus varying x directions
(e.g. example memristor.sp), one has to add the flag
'retraceplot' to the plot command.

Holger Vogt 3d009fef22 Variables xbrushwidth and gridwidth (to be set e.g. in 
.spiceinit) allow setting separately the linewidths of the
graph (xbrushwidth) and the grid (gridwidth).

h_vogt dbd0a5743a Enable utf-8 and UNICODE for string handling. 
preprocessor flag EXT_ASC resets handling to old behaviour.

Add translation between utf-8 and utf-16.
Add angle to fcn DevDrawText.

Jim Monte 57ffe1769f Fixed "phantom vector" issue with plots and crash when plots are resized. See bugs #419 and #423 for details. Also several parameters were changed from char * to const char * in the plotting functions. 2020-03-15 08:50:54 +01:00

h_vogt 42ac9a2859 gnuplot.c, ft_writesimple(), upgrade command 'wrdata' 
- remove a bug to allow printing of vectors with differing scale lengths
- add option 'numdgt' to specify the width of the numbers printed
- add variable wr_singlescale
  use 'set wr_singlescale' to print the scale vector only once
  (vectors need to have equal scale lengths)
- add variable wr_vecnames
  use 'set wr_vecnames' to print the vector names to the first row

rlar 39fdeb0c9a src/frontend/plotting/gnuplot.c, enforce "noenhanced text" mode 
Contrary to older versions gnuplot 5 uses "enhanced text mode" per default.
The strings which we pass to gnuplot don't have "latex" semantics,
  thus consistently enforce "noenhanced text mode".

Add a function quote_gnuplot_string() to escape and quote strings
  in such a way that they will arrive in gnuplot unmodified.
