如何在 Excel 中创建阶梯图？

Question

Suppose I have a set of values: <0-4.5, 1>, <4.6-9.3, 2>, <9.4-12.2, 3> and I want to display a simple, three step graph. One step would span from zero to 4.5 and the height should be 1, the second step from 4.6 to 9.3 and the height would be 2 and so on.

How do I do it in Excel?

Edit: A hack would be to generate pairs: <0,1>, <0.1,1>...<4.4,1>, <4.5,1> and use a scatter graph. But, really!

Use the following data set:

Highlight the data set, and insert a chart using Recommended Charts and pick the one you prefer as shown below.

It can be a bar chart or line chart not necessarily a scatter chart, but the preparation is similar. Charting is not that intuitive in excel and needs a lot of workarounds sometimes.

Answer 2

I'm not sure exactly how you want the graph to look, but another workaround is to select a scatter joined by lines. If you want a gap anywhere, put in a missing value:

+------+---+
|  x   | y |
+------+---+
|    0 | 0 |
|    0 | 1 |
|  4.5 | 1 |
|  4.5 | 0 |
|      |   |
|  4.6 | 0 |
|  4.6 | 2 |
|  9.3 | 2 |
|  9.3 | 0 |
|      |   |
|  9.4 | 0 |
|  9.4 | 3 |
| 12.2 | 3 |
| 12.2 | 0 |
