R语言ggplot作图时纵坐标不均匀怎么解决

Question

​
如下代码：

ggplot(last_week_newuser_x_channel, aes(x = createtime, y = ltv, 0, color = channel_id))+
  geom_line(aes(group = channel_id), size = 1, na.rm = TRUE)+
  geom_point(aes(group = channel_id), size = 3, na.rm = TRUE)+
  labs(title = 'ltv', x = NULL, y = NULL)+ 
  theme(text = element_text(family = "47714613200"), 
        plot.title = element_text(hjust = 0.5))+
  scale_fill_brewer(palette = 'Set2')+
  scale_color_brewer(palette = 'Set2')

结果长这样：

请问怎么让纵坐标均匀分布啊，感谢大家的解答!

回复楼上的朋友，你好像串语言了，ylim(min, max)是python的matplotlib的坐标轴长度设置
但我已经解决啦！原因是纵坐标数字是‘character’
把字符串改成数字就可以了，感谢！
