This class reads tab separated text including time stamp from 10 csv files Use it together with rlHistoryLogger.
Example usage within pvbrowser slot function:
#include "rlhistoryreader.h"
typedef struct // (todo: define your data structure here)
{
rlHistoryReader hist;
}
DATA;...snip...
static int slotButtonEvent(PARAM *p, int id, DATA *d)
{
if(p == NULL || id == 0 || d == NULL) return -1;
if(id == buttonShowPlot)
{
rlTime tStart, tDiff, tEnd;
tStart.year = 2009;
tStart.month = 8;
tStart.day = 29;
tStart.hour = 0;tDiff.hour = 24;
tEnd = tStart + tDiff;
printf("start=%s diff=%s end=%s\n",tStart.getTimeString(), tDiff.getTimeString(), tEnd.getTimeString()); if(d->hist.read("test", &tStart, &tEnd) < 0)
{
printf("could not read test csv file\n");
return 0;
}
const char *line = d->hist.firstLine();
while(*line != '\0')
{
printf("line=%s", line);
const char *values = strchr(line,'');
if(values != NULL)
{
float val1, val2;
sscanf(values,"\t%f\t%f", &val1, &val2);
printf("val1=%f val2=%f\n", val1, val2);
//// fill your buffer for plotting here
}
line = d->hist.nextLine();
}
//// display your xy-graphic from the filled buffer here
}
return 0;
