1. Press aÀ1.
2. Press = to begin editing Plot1.
3. Press = to turn on Plot1.
4. Press the down arrow key ≥ to TYPE and press the right arrow key › to 3rd option and press = to select the histogram.
5. Press the down arrow key ≥… a… 1 to enter L1 for "XLIST".
6. Let FREQ default to 1.
7. Press d and set the Xmin and Xmax appropriately to display the full range of values.
   Note: the Xscl sets the bin width for each bin of the histogram, and Xmin sets the beginning of the first bin. Similarly set Ymin and Ymax to display the full height of each bin.
8. Press h to display the histogram.
