尝试创建一个动画散点图，显示随时间推移的累积数据。我想使用 animate 包为该图创建一个动画：
编辑：为了澄清起见，我希望一次绘制一个单独的数据点并播放数据，以便在循环结束时，所有数据在一次绘制后都会显示出来。我想在给定时间添加一个点，即第一帧只有表格的第一个点，第二帧有前两个点，依此类推。
这是我的尝试：

答案1
好的，这是一个建议。我使用散点图，并使用
scatter/@pre marker code/.append
style={/utils/exec=\pgfmathtruncatemacro{\myscale}{ifthenelse(\coordindex>\iIndex,0,1)},
/tikz/scale=\myscale},
显然，也可以改变不透明度或其他任何方式来隐藏标记。关键在于ifthenelse(\coordindex>\iIndex,0,1)只添加索引不大于动画计数器的标记\iIndex。
这是完整的代码（其中我删除了编辑中不需要的东西）。

如果你（见这里) 替换\usepackage{animate}为\usepackage[export]{animate}，您可以通过以下方式将动画转换为 gif
convert -density 300 -delay 34 -loop 0 -alpha remove <file.pdf> <ani.gif>
