The line graph displays .....
The line graph displays the ozone hole size over Antarctica and three damaging gases to ozone layer over a span of 20 years between 1980 and 2000.

As can be seen from the first line graph，although the ozone hole size over Antarctica experienced a significant increase from approximately 400 in 1980 to 2000 square Km（in thousands）in 1990，there was a considerable decline with under 1500 in 1993 when the number soared greatly to almost 4000 square Km（in thousands）in 2000.
第三段：Three Damaging Gases to Ozone Layer动态变化与静态比较

According to the second line graph that relied on three damaging gases to ozone layer，the stability was witnessed for CFD-11 with about 70 tonnes（in millions）from 1980 to 1982，while the great drop was until 2000（less than 3 tonnes）. However，the trend of CFC-12 remained upward during 20 years from around 30 in 1980 to 50 tonnes（in millions）in 2000 . In addition，N2O from 0 in 1990 at the beginning ascended to the peak at nearly 35 tonnes（in millions）at the end of year of 2000.
结尾段：总结概括（对比或比较）

To sum up，the number of 1980 was much lower than that of 2000 for the ozone hole size over Antarctica，but CFC-12 had a middle level for three damaging gases to ozone layer during the same period.
