我无法去除热图中图块之间的白线。下面是我的代码和图片。以前有人遇到过这种情况吗?
t <- ggplot(Drug_heatmap_df_final,
aes(x=reorder(Drug,Total_Deaths), y=Start_Date, fill=Total_Deaths)) +
geom_tile() +
labs(title="Heatmap of Total Deaths per month by Drug", x="Drug", y="Month") +
theme(plot.title = element_text(hjust=.5)) +
scale_y_date(date_breaks="1 year" , labels = date_format("%b-%Y")) +
theme(axis.text.x = element_text(size=13))
plot(t)
