I want to save the labelText parameter of this function into a .txt file in rows, but "\n" does not work here, the first row is always replaced by the values coming with the next calls of the function.

How can I write the values of this parameter in a .txt file in rows?

Thanks.

By calling FileOpen you reset the file cursor to the beginning. It's like opening a text in Word and placing the cursor to the start. Then you write a line and close it. The previous line is overwritten.

You need to open and close the file outside the log function like so:

int LogHandle;

int OnInit() {
   LogHandle = FileOpen("abc.txt", FILE_READ|FILE_WRITE|FILE_TXT);
   if(LogHandle==INVALID_HANDLE) {
      PrintFormat("Failed to open %s file, Error code = %d", "abc.txt", GetLastError());
      return INIT_FAILED;
   }
   return INIT_SUCCEEDED;
}

void OnDeinit(const int reason) {
   FileClose(LogHandle);
}

void Log_On_Chart(string labelText, color labelColor) {
   FileWrite(LogHandle, labelText);
   //FileWrite(LogHandle, labelText + "\n"); <-- "\n" is done automatically by FileWrite
   ....
   ....
}
