Holger Vogt 7900238bfc Examples for comparing of plotting with ngspice, gnuplot and pyplot 2026-07-19 17:37:26 +02:00
Holger Vogt 560cb6e970 plotting/grid.c, bug fix, avoid string buffer overflow 
Prevent a crash of example/FFT_test.cir.
Buffer 'buf' in function drawlingrid() has been too small.
Increase 'buf' size, and add some protection.

The example file examples/plot/test-small-plot.cir
shows the limits of plotting:
  difference in two numbers at digit 14 is plotted well.
                            at digit 15 is plotted with bugs.
                            at digit 16 is reduced to integer.

consider compiling with
  -O1 -D_FORTIFY_SOURCE=2
for gcc, and
  /GS
for visual studio.
