The graph shows global annual mean surface temperature change from 1880 to 2020. The temperature anomaly begins at -0.2 degrees Celcius in 1880 and dips down to -0.4 degrees by 1910, but then raises steadily to around zero by 1940. From 1940 to 1980 it averages around zero, but then increases steadily all the way to 2000.
