减小条形图#tikzpicture #pgfplots中“靠近坐标的节点”中的字体大小

Question

我试图在下面的代码中减小coords附近的节点中字体的大小，但是我发现避免节点数字重叠的唯一解决方案是减少其十进制数字。

关于如何减少coords附近的节点]的字体的任何建议？

\newcommand{\figureHeight}{0.5625} %% 16:9
\pgfplotsset{
    compat           = 1.13,
    grid             = major,
    enlarge x limits = 0,
    cycle list name  = tum,
    major grid style = {dotted},
    minor grid style = {dotted},
    width            = \hsize,
    %width            = \hsize * 0.9,
    height           = \hsize * 0.9 * \figureHeight,
    legend style     = { at = {(0.98,0.96)}, anchor = north east,}
}

您可以使用nodes near coords style={font=\tiny}（或您喜欢的任何大小）来更改样式
