Power BI-使用M添加列以计算2年的数据

Question

I have 2 years of data on a bar chart and an x-axis that I created by concatenating Year and Month Number into a separate column called "Year - Month"

Number.ToText([Year]) & Number.ToText([Month Number])

The result is

20171
20172
20173
20174
...
201711
201712
20181
20182
20183
20184
20185
...

How can I create a calculated column in M to add a number column that counts 1 - 24 which will allow me to sort the x axis on the chart?

Also how can I make this dynamic allowing any new data in the report to auto increment to 25, 26, 27... into year 3?

Try in Power Query editor:

Go to > Add Column > Index Column > From 1

并非完全符合您的要求，但是您可能更愿意创建一个日期列，该日期列可用于轴。

= #date([Year],[Month Number],1)
