Giles Atkinson 1d435daed7 Support use of XSPICE event nodes with iplot. 
In graf.c, local function set() is renamed setflag() to avoid conflict
with a newly-visible global function with the same name.
 2025-04-12 18:20:19 +02:00
Giles Atkinson fc76d4d63b Always check for GUI events during simulation, if any graphs exist. 
Previously this check was only made if an iplot window existed.
The 100W.sp example displayed frozen windows with X11-based plotting.

Holger Vogt c79eb348a2 iplot on macOS is totally slow, thus unusable, due to problems with 
repeated calls to XSync. Skipping them still allows iplotting.

Giles Atkinson d549b882df Fix a crash that happens after an iplot window is zoomed and closed 
while active.
 2024-12-27 11:14:53 +01:00
Giles Atkinson 5114d6c2f4 Add an option to the iplot command: -d sets the number of simulation 
steps before the window is shown.  The value can be chosen to
limit rapid resizing when starting and that is used in the PLL examples.
 2023-07-15 11:29:32 +02:00
Giles Atkinson 45015f974d Add a "-w" option to the iplot command. It sets a width for the 
window (in the current scale units) so that it does not re-scale
on overflow, but instead plots recently-generated data on a fixed scale.
 2023-05-27 10:46:45 +02:00
Giles Atkinson 7a5514a1ff In graf.c change local function set() to do what you might expect, 
rather than the opposite.  Also fix a debug message.

Giles Atkinson 79fcb5d4bd Fix plotting bug reported by Robert Turnbull: ngspice-devel 2023-02-10. 2023-03-18 14:34:50 +01:00
Giles Atkinson 41e48b954d Rename a variable so that it does not clash with one in outer scope. 2022-04-26 10:37:28 +02:00
Giles Atkinson 519915202f Fix Bug #577 "Zooming iplot drops vectors" and three crashes when 
the iplot window is closed during simulation.
 2022-04-26 10:36:55 +02:00
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.
 2022-01-28 12:24:51 +01:00
Holger Vogt f61ea3aa96 if 'set nounits' is given, plotting of the units is suppressed 
(they may be added manually to the y and x labels for SI conformity).

Holger Vogt 14b154f5f3 Copy the scale vector as well and attach it to the data vector. 
Remove it again when the graph is destroyed.

Holger Vogt c2cf4d7eda required for reliable re-plotting, however still has the 
return line bug no #472
 2020-03-15 08:51:13 +01:00
Holger Vogt acbec3ae81 Preliminary 'fix' to a plotting bug (visible return line in an array of curves): 
Partially undo code added in commit 10415875f4/
This will need further discussion or updates
 2020-03-15 08:51:13 +01:00
Holger Vogt 32722ecc57 some missing brackets, typos 2020-03-15 08:51:12 +01:00
Vogt 728ddae41e Set the color tables and linewidths personal for each graph, 
added to strucht graph
Use only these data for plotting.
If zooming a plot windows, set as an extra parameter the graph id
of the 'mother graph'. Copy its color and line data to the new graph.
This is done by an extra parameter sgraphid to the internal plot
command that is issued in fcn PlotWindowProc().
Thus zooming will keep the background, text/line and graph colors.
Function setcolor() will always look into the colorarray of the
current graph.

Holger Vogt 800cd05f3d new variable nolegend: with 'set nolegend' plotting of 
the legend is suppressed.

Holger Vogt fed7ef378f add variable ticchar, allow an arbitrary character as ticmark 2020-03-15 08:51:11 +01:00
Holger Vogt 8751092812 Enable separate linewidths for grids and graphs. 
New variable gridwidth overrides xbrushwidth for graphs.
Fcn DevDrawLine() with boolean flag if grid is plotted.
Postscript, Gnuplot and X11 not (yet) supported.

Jim Monte 8141a634d7 Fixed several issues related to plotting and vector lifetimes and made ownership of vectors clearer. The issues in bugs 419, 423, 425, and 426 were related and were addressed here. 2020-03-15 08:50:54 +01:00
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

ignored by all others
