# 2024 Week 30 | Sigma: Can you show partial or whole months?

## Introduction

This week’s challenge was inspired by a lively discussion I was a part of, covering what date calculations a data analyst should or should not know. We’ve already covered several common ones, such as the current time period vs the prior time period. So this week, I wanted to add another to the list: identifying partial months!

Have fun!

## Requirements

• Add a data table element from the Plugs Electronic Folder
• Sigma Sample Database > Retail > Plugs Electronic > Plugs Electronics Hands On Lab
• Create a Switch to control if the data contains the current month or not
• Create a KPI showing Revenue by week compared to this week last month.
• Include a dynamic title based on the date range
• Include an indicator of the start of the month on the trend line
• Match other formatting
• Create a bar and line chart showing the Revenue and Cost of Goods by Week Number and Region for the last 4 months and potentially the current month
• Have the lines be colored differently:
• Here are the colors I used; you can choose different ones
• Revenue: DDDDDD
• Current Month COGs: E91E63
• Other Months COGs: 388E3C
• Match other formatting

• Revenue = Sum([Price] * [Quantity])
• COGS = Sum([Cost] * [Quantity])

## Solution

1. Create a “Show partial or whole month” switch control element.
2. In the parent table element, create a formula for if the date is within the selected time frame.
1. If([New-Control], True, (InDateRange([Date], “current”, “month”)))
3. In the same table, create a week of date calculation
1. DatePart(“week”, [Date])
4. For the KPI
1. Create a child KPI off of the parent table element
2. Put Revenue as the value
3. Week of Date as the timeline
4. Comparison is “This week last month”
5. Add a reference line on the x-axis with the custom formula of
1. If([New-Control], DateTrunc(“month”, Today()))
6. Change the title to be dynamic with the Min & Max Date formatted to Month and year
5. For Combo Chart
1. Add a combo chart with the Week of Date as the X-Axis
2. On the Y-Axis add three calculations:
1. Revenue (either the Metric or sum([Revenue])
2. Current Month COG
1. If(InDateRange([PLUGS_ELECTRONICS_HANDS_ON_LAB_DATA/Date], “current”, “month”), [Metrics/COGS])
3. Other Months COG
1. If(Not (InDateRange([PLUGS_ELECTRONICS_HANDS_ON_LAB_DATA/Date], “current”, “month”)), [Metrics/COGS])
3. Display Revenue as bars and COGS as lines
4. Color each measure separately
5. Trellis the Combo Chart by Store Region
