我的字典为：

    ```{'0.0': 2.445616223564293,'0.05': 2.445594095119315,'0.1': 2.4455740588234223,'0.15': 2.4455560866270947,'0.2': 2.4455401509059596,'0.25': 2.4455262244535803,'1.0': 2.4455411399961293,'1.05': 2.44555597697399,'1.1': 2.4455724183134344,'1.15': 2.4455904432448716,'1.2': 2.445610031303073,'1.25': 2.4456311623222002,'2.0': 2.4461204322901566,'3.0': 2.447205696789686,'4.0': 2.4486856713473726,'5.0': 2.4504762863004363,'10.0': 2.4623061878090624,'20.0': 2.4922549001247876}```

此处所有值都相差很小。但是，当我使用matplotlib对其进行绘制时，该图并不明显。

I want to plot "keys" in x-axis and "values" in y-axis and then find x which has minimum y value by looking the plot.

我尝试了以下代码：

       ```plt.plot(*zip(*data))```

但是情节不清楚。我该如何解决这个问题，以使图可以清楚地显示出值的差异。
