KSPMonitorSNESResidualDrawLG#
Plots the linear KSP residual norm and the SNES residual norm at each iteration of an iterative solver.

PetscErrorCode KSPMonitorSNESResidualDrawLG(KSP ksp, PetscInt n, PetscReal rnorm, PetscViewerAndFormat *vf)
Collective
Input Parameters#
ksp - iterative context
n - iteration number
rnorm - 2-norm (preconditioned) residual value (may be estimated).
vf - The viewer context, created with
KSPMonitorSNESResidualDrawLGCreate()

KSPMonitorSNESResidualDrawLG()
Note#
This is not called directly by users, rather one calls SNESMonitorSet(), with this function as an argument, to cause the monitor
to be used during the SNESSolve()
