# 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
- ***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.
