怎么在mathematica中给曲线上的点加上坐标表示

ListPlot[{{2.000,
12}, {1.900, 14}, {1.8, 15}, {1.7, 16}, {1.6, 19}, {1.5, 21}, {1.4, 29}, {
1.3, 39}, {1.2, 64}, {1.18, 69}, {1.17, 70}, {1.169, 70}, {1.164,
70}, {1.161, 70}, {1.159, 71}, {1.158, 71}, {1.157, 71}, {1.155,
70.8}, {1.150, 70}, {1.114,
69}, {1.112, 61}, {1.110, 57}, {1.100,
52}, {1.00, 25}}, PlotJoined -> True, AxesLabel -> {"x", " y"}] 想把一部分点表示在曲线旁边
我想把点坐标也表示在图上。不好意思，没表达清楚

Answer 1

你的意思是指要把这些点表示在曲线上吗？“旁边”怎么解释？
ListLinePlot[{{2.000, 12}, {1.900, 14}, {1.8, 15}, {1.7, 16}, {1.6,
19}, {1.5, 21}, {1.4, 29}, {1.3, 39}, {1.2, 64}, {1.18, 69}, {1.17,
70}, {1.169, 70}, {1.164, 70}, {1.161, 70}, {1.159, 71}, {1.158,
71}, {1.157, 71}, {1.155, 70.8}, {1.150, 70}, {1.114, 69}, {1.112,
61}, {1.110, 57}, {1.100, 52}, {1.00, 25}}, Mesh -> All,
AxesLabel -> {"x", " y"}]

Answer 2

ListPlot[Tooltip@{{2.000, 12}, {1.900, 14}, {1.8, 15}, {1.7,
16}, {1.6, 19}, {1.5, 21}, {1.4, 29}, {1.3, 39}, {1.2, 64}, {1.18,
69}, {1.17, 70}, {1.169, 70}, {1.164, 70}, {1.161, 70}, {1.159,
71}, {1.158, 71}, {1.157, 71}, {1.155, 70.8}, {1.150, 70}, {1.114,
69}, {1.112, 61}, {1.110, 57}, {1.100, 52}, {1.00, 25}},
AxesLabel -> {"x", " y"}, Joined -> True]
这样怎么样啊？鼠标一移近，就显示坐标。

可以用另外一个ListPlot函数把你要加的点画上，然后用Show函数将个曲线绘制在一张图上。
