返回：（“NTK 553 FAE 5”、“8DG 62496 AA”、“TOM-100 G-Q-LR 4”、“ORM-CXH 1”等）

chart.SeriesCollection(1).Points(1).Fill.ForeColor.RGB

但它似乎是只读的。

>>> chart.SeriesCollection(1).Points(1).Fill.ForeColor.RGB = 50

During handling of the above exception, another exception occurred:

我还试了几种变体：图表.系列集合（1）.点（1）.填充.前景色. RGB.设置属性
但是运气不好，有没有可能改变数据点的颜色？
