我是DAX新手并且有关于过滤措施的问题。正如您在附件中看到的那样，我希望仅针对2018年过滤这两个度量volume CY（当前年份）和volume LY。
Volume LY Volume CY
2016 65.024.635
2017 65.024.635 63.602.450
2018 63.602.450 21.597.407
我想将过滤与指标（Counter）相关联。该计数器的值在[0-3]范围内。每年都有学期，例如当前年度有2017年第1学期和第1学期 - 2016年第2期和第3期 - 4年和第5期。在这种情况下，我想为计数器选择1，它应该过滤semester <= 1 2018年：
Volume LY Volume CY
2018 63.602.450 21.597.407
但是，如果我使用：
过滤度量volume CY
FILTER(ALLSELECTED(Table);Table[Semester]<=MAX('Table2'[Counter]));
然后测量Volume LY会自动过滤semester <= 1并且它不会显示LY的值。我的问题是：我如何使用过滤函数来获取当年的两种度量值？
测量当前体积年度：
Volume_CY:=CALCULATE(
[Volume];
'Scenario'[Scenario1]=1;
FILTER(Table;Table[Semester]<=MAX('Table2'[Counter])))
测量体积LY：
Volume LY:= CALCULATE(
[Volume_CY];
FILTER(ALLSELECTED(Table);Table[Semester]<=MAX('Table2'[Counter]));
FILTER(ALL(Table[Year]))
以下是计数器1和方案1的两个测量结果：正如您所看到的，它没有显示LY值，应该是63.602.450。
Scenario 1
Counter 1
Volume LY Volume CY
2018 21.597.407
Total 21.597.407
现在我有这样的结果：
Volume CY Volume LY
20151 77.222.12 77.222.12
20152 88.868.719 88.868.719
20161 87.987.22 87.987.22
20162 92.906.793 92.906.793
20171 101.102.12 101.102.12
20172 105.029.725 105.029.725
这就是我所期待的：
Volume CY Volume LY
20151 77.222.12
20152 88.868.719 49.123.12
20161 87.987.22 77.222.12
20162 92.906.793 88.868.719
20171 101.102.12 87.987.22
20172 105.029.725 92.906.793
答案 0 :(得分：0)
修改
给出以下源数据：
year, Volume CY
20151, 77222.12
20152, 88868.719
20161, 87987.22
20162, 92906.793
20171, 101102.12
20172, 105029.725
使用以下计算列可以实现预期结果：
Volume LY = CALCULATE(SUM(Table[Volume CY]),
ALL(Table1),
Table[year] = EARLIER(Table[year])-10)
结果是：
year, Volume CY, Volume LY
20151, 77222.12,
20152, 88868.719,
20161, 87987.22, 77222.12
20162, 92906.793, 88868.719
20171, 101102.12, 87987.22
20172, 105029.725, 92906.793
哪个过滤＆＃34; year＆＃34;列。
（下面的旧答案）
滚动总和：
year semester volume
2016 1 123
2017 3 1345
2018 5 3465
2016 2 3465
2017 4 3465
2018 6 634
计算列：
VCY = CALCULATE(SUM(Table1[volume]),
ALL(Table1),
Table1[semester] <= EARLIER(Table1[semester]))
VLY = CALCULATE(SUM(Table1[volume]),
ALL(Table1),
Table1[semester] <= EARLIER(Table1[semester]) - 2)
结果：
year, semester, volume, VCY, VLY
2016, 1, 123, 123,
2016, 2, 3465, 3588,
2017, 3, 1345, 4933, 123
2017, 4, 3465, 8398, 3588
2018, 5, 3465, 11863, 4933
2018, 6, 634, 12497, 8398
每年滚动总和：
VCY =
VAR RowYear = Table1[year]
RETURN CALCULATE(SUM(Table1[volume]),
ALL(Table1),
table1[year] = RowYear,
Table1[semester] <= EARLIER(Table1[semester]))
VLY =
VAR RowYear = Table1[year]-1
RETURN
CALCULATE(SUM(Table1[volume]),
ALL(Table1),
table1[year] = RowYear,
Table1[semester] <= EARLIER(Table1[semester])-2)
结果：
year, semester, volume, VCY, VLY
2016, 1, 123, 123,
2016, 2, 3465, 3588,
2017, 3, 1345, 1345, 123
2017, 4, 3465, 4810, 3588
2018, 5, 3465, 3465, 1345
2018, 6, 634, 4099, 4810
答案 1 :(得分：0)
结果如下：
#!/usr/bin/env python
import os
import subprocess
import psutil
def getBatteryLevel():
BATTERY_CMD = ["/usr/sbin/ioreg", "-l"]
GREP_CMD = ["/usr/bin/egrep", "Capacity|ExternalChargeCapable"]
process = subprocess.Popen(BATTERY_CMD, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
grep = subprocess.Popen(GREP_CMD, stdin=process.stdout, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
grep.wait()
output = grep.communicate()[0]
batteryStatus = output.split("\n")
maxCapacity = float(batteryStatus[1].split("=")[1].lstrip())
curCapacity = float(batteryStatus[2].split("=")[1].lstrip())
remaining = 100 * (curCapacity / maxCapacity)
print "BATTERY LEVEL : "
print remaining
getBatteryLevel()
这就是我所期待的：
Volume CY Volume LY
20151 77.222.12 77.222.12
20152 88.868.719 88.868.719
20161 87.987.22 87.987.22
20162 92.906.793 92.906.793
20171 101.102.12 101.102.12
20172 105.029.725 105.029.725
如果我按特定年份/半年过滤，例如20162它应该显示以下内容：
Volume CY Volume LY
20151 77.222.12
20152 88.868.719 49.123.12
20161 87.987.22 77.222.12
20162 92.906.793 88.868.719
20171 101.102.12 87.987.22
20172 105.029.725 92.906.793
这就是我所得到的：`过滤器（全部（表）;表（年）= MAX（表（年）-10）） - ＆gt; 缺少卷CY的总计！
Volume CY Volume LY
20162 92.906.793 88.868.719
