#include "petscts.h" PetscErrorCode TSMonitorLGCtxCreate(MPI_Comm comm,const char host[],const char label[],int x,int y,int m,int n,PetscInt howoften,TSMonitorLGCtx *ctx)Collective on TS
| host | - the X display to open, or null for the local machine | |
| label | - the title to put in the title bar | |
| x, y | - the screen coordinates of the upper left coordinate of the window | |
| m, n | - the screen width and height in pixels | |
| howoften | - if positive then determines the frequency of the plotting, if -1 then only at the final time |
| ctx | - the context |
| -ts_monitor_lg_timestep | - automatically sets line graph monitor + -ts_monitor_lg_timestep_log - automatically sets line graph monitor | |
| -ts_monitor_lg_solution | - monitor the solution (or certain values of the solution by calling TSMonitorLGSetDisplayVariables() or TSMonitorLGCtxSetDisplayVariables()) | |
| -ts_monitor_lg_error | - monitor the error | |
| -ts_monitor_lg_ksp_iterations | - monitor the number of KSP iterations needed for each timestep | |
| -ts_monitor_lg_snes_iterations | - monitor the number of SNES iterations needed for each timestep | |
| -lg_use_markers <true,false> | - mark the data points (at each time step) on the plot; default is true |
One can provide a function that transforms the solution before plotting it with TSMonitorLGCtxSetTransform() or TSMonitorLGSetTransform()
Many of the functions that control the monitoring have two forms: TSMonitorLGSet/GetXXXX() and TSMonitorLGCtxSet/GetXXXX() the first take a TS object as the first argument (if that TS object does not have a TSMonitorLGCtx associated with it the function call is ignored) and the second takes a TSMonitorLGCtx object as the first argument.
One can control the names displayed for each solution or error variable with TSMonitorLGCtxSetVariableNames() or TSMonitorLGSetVariableNames()
