The graph is titled “School 2 Natural Gas”. The vertical axis is labeled “Error Rate (percent)” and ranges from negative 10.00 to 10.00 in increments of 5.00 units. The horizontal axis shows the months from January to December. A legend at the top identifies two metrics: “C V (R M S E)” and “M B E”. January: C V (R M S E): 5.0; M B E: 3.4 February: C V (R M S E): 6.2; M B E: negative 5.8 March: C V (R M S E): 1.0; M B E: 0.9 April: C V (R M S E): 1.2; M B E: 1.3 November: C V (R M S E): 1.6; M B E: 4.8 December: C V (R M S E): 3.0; M B E: negative 2.6 The remaining months have no bars.
