使用 TikZ/PGFPlots 设置颜色条内的 ytick 时出现问题，没有轴

Question 1

实现此目的的一种方法是执行以下操作：

使用范围的实际值meta，因此point meta min=-2e-3, point meta max=2e3
关闭刻度标签的整体缩放：scaled y ticks = false

使用包解析并格式化刻度值siunitx，这可以非常精细地控制数字格式。加载\usepackage{siunitx}，然后设置

yticklabel={
    \num[
        scientific-notation = fixed,
        fixed-exponent = -3,
        output-exponent-marker = \text{e},
        round-integer-to-decimal = true,
        round-mode = places,
        round-precision = 1
    ]{\tick}
