hello everybody,
I need to draw a figure out which has a data array, well, when trying to set
the Pt_ARG_TREND_FLAGS, I got problem: the default is:
Pt_TREND_HORIZONTAL|Pt_TREND_RIGHT_TO_LEFT
|Pt_GRID_IS_TRANSLUCENT
it shows me the figure on the right side, when I changed only the
Pt_TREND_LEFT_TO_RIGHT(while kept the other part there), nothing happend.
besides that, I want to use PtSetResource( ) function to set it, how to play
the “len” of PtSetResource here?? because when I change the “len” with
different numbers, my figure changes position.
here is my code:
/* Standard headers */
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <string.h>
/* Local headers */
#include “ablibs.h”
#include “x26.h”
#include “abimport.h”
#include “proto.h”
#include <math.h>
//#include <afxcoll.h>
int
green_function( PtWidget_t *widget, ApInfo_t *apinfo, PtCallbackInfo_t
*cbinfo )
{
int color= 0;
int i;
short int min, max;
short int try[500];
long direction=1;
/* eliminate ‘unreferenced’ warnings */
widget = widget, apinfo = apinfo, cbinfo = cbinfo;
for (i=0; i<200; i++)
{
try = sin(i23.1415926/200)*10;
}
//CPtrArray temp_array;
min=-10;
max=10;
PtSetResource(ABW_end_window, Pt_ARG_TREND_INC, 1,0);
PtSetResource(ABW_end_window, Pt_ARG_TREND_MAX,max,0);
PtSetResource(ABW_end_window, Pt_ARG_TREND_MIN,min,0);
PtSetResource(ABW_end_window, Pt_ARG_TREND_DATA, try,200);
PtSetResource(ABW_end_window, Pt_ARG_TREND_FLAGS,
Pt_TREND_HORIZONTAL|Pt_TREND_LEFT_TO_RIGHT,0);
return( Pt_CONTINUE );
}
