Holger Vogt 20d5919e59 Terminal setting to X11 fails in macOS, and is not required

Setting terminal here is redundant, so remove this setting.

Holger Vogt 12a93c9fe6 Update to plotting of event nodes: 
Distance is now 1.5, scaling and cutouts are possible
(with some lack of precision).

Still missing: y axis labeling (no numbers, but node names).
 2022-02-21 20:19:56 +01:00
Holger Vogt 342a16d6e1 Add a flag 'alle' (all event nodes) to the plot command (and maybe others). 
All event nodes with length greater than 1 are translated to vectors
with a common scale (named step) and are assembled in a new plot
named 'digital'. They may be plotted or otherwise used in a
.control section.

 2022-02-17 15:50:05 +01:00
Holger Vogt 954cc86e59 Add new or upgraded functions as of 01-09-22. 
Add a function prototype for cmod.
Rename function conj to conju because conj
is already defined differently in complex.h
 2022-02-17 15:49:53 +01:00
Holger Vogt 94a73ffef2 Add changes from 01-09-22, but without the extra extern calls, 
which have led to a bunch of warnings when compiling with gcc.

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
Holger Vogt 62f326b9d0 Fix a bug from previous commit: min -> MIN 2022-02-07 22:39:27 +01:00
Holger Vogt 0eb272243f Enable RKM notation also for inductors (e.g. 1u2 for 1.2u) 2022-02-07 16:00:29 +01:00
Holger Vogt 640fa7e17b bug 578 crash when scale is too short 
Warning message if scale and vector length do not match.
Restrict number of points plotted to the smaller of both.
 2022-02-07 15:59:43 +01:00
Holger Vogt 4f82a24df2 Add parameter 'isgrid' to plotting of arcs. 
Smithgrid and polar plots could not discern between xgridwidth and
xbrushwidth. This is now available, similar to straight line plotting.
Tested also for PS and SVG.

Giles Atkinson 16f586b65e Respect the "tstart" parameter when saving event node data (XSPICE). 
Fixes Support Request #47: "XSpice memory usage (TRAN TSTART effect)".
 2022-01-28 12:25:36 +01:00
Giles Atkinson 6494befb2f Request backing store for X11 plot windows. When supported by the X server 
windows are redrawn vey quickly without replotting.
 2022-01-28 12:24:58 +01:00
Giles Atkinson f4285384e7 Add code in graf.c to merge connected lines with the same slope before 
plotting.  This speeds output and reduces file size when the vector
length is much larger than the number of pixels.  It should help with
Feature Request #58:
  "Graph plotting under windows redraw very slow and hard to work with",
but is not a full fix.

Holger Vogt ce9bc9fc64 The re-painting due to mouse-click under MS Windows is caused by line 561 
of windisp.c. Upon left mouse button up the plot recangle is invalidated,
and a WM_PAINT message is generated (same on line 614 for right mouse
button up). If not re-pained, artifacts may be left on the canvas after
collecting coordinate data.

Shifting the command InvalidateRect to a place where it becomes active
only after the mouse has been moved, does the trick. Simple clicking
(right or left) will not cause a re-paint any more.
