Since July 8, when the United States and South Korea jointly announced the deployment of the Sade anti-missile system in South Korea, the domestic controversy over the matter and the strong dissatisfaction of some countries in the region continued to ferment. "Sade" (THAAD), the "last High Altitude Zone defense system", is the U.S. Missile Defense Bureau and the United States Army under the land-based war zone antimissile system. South Korea, ignoring the interests of China, Russia and other reg

with the GGPLOT2 in the R language, it seems that two packages are used and the likelihood is developed by the same person! The original author also said on GITHUB that the PYTHON library will no longer be updated! However, ggplot2 is really a drawing artifact, which is almost the only reason I am still using the R language. Therefore, matplotlib is required no matter which library you want to use. Although his syntax is complex, he is flexible. you can draw almost any image you want. Here we
