The line graph consists of a horizontal axis which is labeled from left to right as follows: “June-2020”, “July-2020”, “August-2020”, “September-2020”, “October-2020”, “November-2020”, “December-2020”, “January-2021”, “February-2021”, “March-2021”, “April-2021”, “May-2021”, “June-2021”, “July-2021”, “August-2021”, “September-2021”, “October-2021”, “November-2021”, “December-2021”, “January-2022”, “February-2022”. The vertical axis on the left is labeled “dollar per ton” and ranges from 0 to 800 in increments of 100 units. The legend at the top includes five lines: a thick black line for “Target”, an orange line for “Holdout underscore 24 features”, a grey line for “Holdout underscore 6 features”, a yellow line for “Holdout underscore 3 features”, and a blue line for “A R I M A X (1, 1, 1)”. The data from the graph is as follows: The black line labeled “Target” begins at (June-2020, 230), passes through several points with a steady upward trend, and then terminates at (February-2022, 520). The orange line labeled “Holdout underscore 24 features” begins at (June-2020, 300), passes through several points showing a gradual rise, and then terminates at (February-2022, 480). The grey line labeled “Holdout underscore 6 features” begins at (June-2020, 240), passes through several points closely following the Target line, and then terminates at (February-2022, 530). The yellow line labeled “Holdout underscore 3 features” begins at (June-2020, 240), passes through several points showing a similar trajectory to the grey line, and then terminates at (February-2022, 540). The blue line labeled “A R I M A X (1, 1, 1)” begins at (June-2020, 210), passes through several points below all other lines, before rising to meet the other lines, and then terminates at (February-2022, 530).
