I'm trying to find a glitch in an FPGA simulation. The data stored in a file
is:
(simulation time, y)
In reality, if I plot that I get large gaps because the simulation time
continues and data is only output periodically. In other words simulation time
is not continuous. I'd like to view the data without the gaps, but with
simulation time annotating the x-axis so I can determine where the glitch
occurs.
I've tried a variety of things:
#ax1.plot(x1, x1,'b--')
#ax3 = ax2.twiny()
ax2.set_xticklabels(simtimedata, fontdict=None, minor=False, rotation = 45)
ax2.plot( idatanp.real,'k--',idatanp.imag,'g.-')
#ax2.plot(xdat, idatanp.real,'k--',xdat,idatanp.imag,'g.-')
#ax3.plot(simtimedata, idatanp.real,'k--',alpha=0)
but cannot get the axis to both show the data all together AND show where the
glitch occurs. I thought the twiny might help to put another x axis up so I
could plot the data first with the x axis incrementing based on when the data
is read in, and then trying to place labels showing simulation time.
Does anyone have any ideas how I could do this?
