how to use plx-daq to compute readings from mpu-9150

hello,i want to get the raw data from mpu-9150 to excel using plx-daq.The plx-daq is connecting but now showing the data.Here is my code
// I2C device class (I2Cdev) demonstration Arduino sketch for MPU9150 class
// 10/7/2011 by Jeff Rowberg jeff@rowberg.net
// Updates should (hopefully) always be available at GitHub - jrowberg/i2cdevlib: I2C device library collection for AVR/Arduino or other C++-based MCUs
//
// Changelog:
// 2011-10-07 - initial release

What you have posted is not complete.

You may have a problem because the version of Excel is too recent. I understand people have claimed PLX will work on recent versions, but the general view is that office 2003 is the newest you can use - I think.

You can test your code is kosher by sending it to the monitor in the usual manner

I believe the only code you have that matters is

Serial.print(gx ); Serial.print(",");
Serial.print(gx2); //Serial.print("\n");

Which looks a bit naked in view of the absence of Excel commands, and I guess you are doing nothing to feed the y-axis.

A more typical feed to Excel might be

 Serial.print("DATA,TIME,");  // Excel commands 
  Serial.print(InTemp);
  Serial.print(" ,  ");
  Serial.print(OutTemp);
  Serial.print(" ,  ");
  Serial.print(diff);
  Serial.print(" ,  ");
  Serial.println(DrainTemp);

Time to y-axis

Note that each record's ending is noted by using println(), not print().
