同一日期时间高图表中的多个数据点

Question

我使用折线图绘制图表。 我在同一个日期时间有多个数据点，如下所示。

[[Date.UTC(2015,05,25,03,29), 560], [Date.UTC(2015,05,25,03,29), 548],
[Date.UTC(2015,05,25,03,29), 628], [Date.UTC(2015,05,25,03,29), 740], 
[Date.UTC(2015,05,25,03,29), 380], [Date.UTC(2015,05,25,03,29), 548], 
[Date.UTC(2015,05,25,03,29), 628], [Date.UTC(2015,05,25,03,29), 740], 
[Date.UTC(2015,05,25,03,29), 380], [Date.UTC(2015,05,25,03,29), 548], 
[Date.UTC(2015,05,25,03,29), 628], [Date.UTC(2015,05,25,03,29), 740], 
[Date.UTC(2015,05,25,03,29), 380], [Date.UTC(2015,05,25,03,29), 548], 
[Date.UTC(2015,05,25,03,29), 628], [Date.UTC(2015,05,25,03,29), 740], 
[Date.UTC(2015,05,25,03,29), 7740], [Date.UTC(2015,05,25,03,29), 548], 
[Date.UTC(2015,05,25,03,29), 628], [Date.UTC(2015,05,25,03,29), 740], 
[[Date.UTC(2015,05,25,03,29), 380], [Date.UTC(2015,05,25,19,46), 204], 
[Date.UTC(2015,05,25,19,46), -248], [Date.UTC(2015,05,25,19,46), 220], 
[Date.UTC(2015,05,25,19,46), -192], [Date.UTC(2015,05,25,19,46), -696], 
[Date.UTC(2015,05,25,19,46), -132], [Date.UTC(2015,05,25,19,46), -76],
[Date.UTC(2015,05,25,19,48), 2688], [Date.UTC(2015,05,25,19,49), 1668],
[Date.UTC(2015,05,25,19,49), 788], [Date.UTC(2015,05,25,19,49), 584],
[Date.UTC(2015,05,25,19,49), 100]]

如果我绘制上述值，我只能看到最新值。

for [Date.UTC(2015,05,25,03,29) : 380
for [Date.UTC(2015,05,25,19,46) : -76
for [Date.UTC(2015,05,25,19,49) :100

此外，如果我在excel中下载图表值，它只有以上值。

如何在Excel图表中同时查看所有数据点？
