# TSMonitorDrawSolution

Monitors progress of the `TS` solvers by calling `VecView()` for the solution at each timestep

## Synopsis

    #include "petscts.h"
    PetscErrorCode TSMonitorDrawSolution(TS ts, PetscInt step, PetscReal ptime, Vec u, void *dummy)

Collective

## Input Parameters

- ts - the `TS` context

- step - current time-step

- ptime - current time

- u - the solution at the current time

- dummy - either a viewer or `NULL`

## Options Database Keys

- -ts_monitor_draw_solution - draw the solution at each time-step

- -ts_monitor_draw_solution_initial - show initial solution as well as current solution

## Notes

The initial solution and current solution are not displayed with a common axis scaling so generally the option `-ts_monitor_draw_solution_initial` will look bad

This is not called directly by users, rather one calls `TSMonitorSet()`, with this function as an argument, as well as the context created with `TSMonitorDrawCtxCreate()` and the function `TSMonitorDrawCtxDestroy()` to cause the monitor to be used during the `TS` integration.
