Slicers (list, dropdown, between) in Power BI - Dashboard Guide

Dashboard Mode - Slicers (list, dropdown, between)

Dashboard Goal

Help the sales manager explore sales data by filtering products, regions, and sales dates using slicers.

Sample Data

OrderID	Product	Region	SalesDate	SalesAmount
1001	Chair	East	2024-01-15	250
1002	Table	West	2024-02-20	450
1003	Desk	East	2024-03-05	300
1004	Chair	South	2024-01-25	200
1005	Table	North	2024-02-10	500
1006	Desk	West	2024-03-15	350
1007	Chair	North	2024-01-30	275
1008	Table	South	2024-02-25	400

Dashboard Components

• KPI Card: Total Sales Amount
  Formula: Total Sales = SUM(Sales[SalesAmount])
  Shows the sum of sales filtered by slicers.
• Bar Chart: Sales by Product
  Shows total sales amount for each product, filtered by slicers.
• Table: Sales Details
  Shows OrderID, Product, Region, SalesDate, and SalesAmount filtered by slicers.
• Slicer (List): Product
  Allows selecting one or multiple products to filter all visuals.
• Slicer (Dropdown): Region
  Allows selecting one region from a dropdown to filter all visuals.
• Slicer (Between): SalesDate
  Allows selecting a date range to filter all visuals.

Interactivity

All slicers filter the KPI card, bar chart, and sales details table simultaneously.

• Product Slicer (List): Selecting products filters data to only those products.
• Region Slicer (Dropdown): Selecting a region filters data to that region only.
• SalesDate Slicer (Between): Selecting a date range filters data to sales within those dates.

Changing any slicer updates all visuals instantly, helping explore sales by different slices.

Self Check

Try this: Add a filter selecting Product = Chair and Region = East with SalesDate between 2024-01-01 and 2024-01-31.

Question: Which rows remain in the sales details table and what is the total sales amount shown in the KPI card?

Answer: Only OrderID 1001 remains (Product: Chair, Region: East, SalesDate: 2024-01-15, SalesAmount: 250). Total Sales KPI shows 250.

Key Result

Sales dashboard with slicers for Product (list), Region (dropdown), and SalesDate (between) filtering total sales, sales by product chart, and sales details table.

Practice

1.

What is the main purpose of a slicer in Power BI?

easy

A. To import data from external sources

B. To create calculated columns

C. To write DAX formulas

D. To filter report data visually and interactively

Solution

1. Step 1: Understand slicer functionality

   Slicers are visual tools that let users filter data on reports easily by selecting values.

2. Step 2: Compare options to slicer purpose

   Only To filter report data visually and interactively describes filtering data visually and interactively, which matches slicer use.

3. Final Answer:

   To filter report data visually and interactively -> Option D

4. Quick Check:

   Slicer = Visual filter [OK]

Hint: Slicers filter data visually, not for calculations [OK]

Common Mistakes:

• Confusing slicers with data import tools
• Thinking slicers create calculations
• Assuming slicers write DAX formulas

2.

Which slicer type should you use to let users select a range of dates?

easy

A. Between slicer

B. List slicer

C. Dropdown slicer

D. Checkbox slicer

Solution

1. Step 1: Identify slicer types for date ranges

   Between slicers allow users to pick a start and end value, ideal for date or numeric ranges.

2. Step 2: Eliminate other slicer types

   List and dropdown slicers select single or multiple discrete values, not ranges. Checkbox slicer is not a standard type.

3. Final Answer:

   Between slicer -> Option A

4. Quick Check:

   Date range = Between slicer [OK]

Hint: Use between slicer for numeric or date ranges [OK]

Common Mistakes:

• Choosing list or dropdown for ranges
• Confusing checkbox slicer with dropdown
• Not knowing between slicer exists

3.

Given a dropdown slicer on a "Category" column with values: "A", "B", "C", what happens if the user selects "B"?

medium

A. The report filters to show rows where Category is blank

B. The report shows all rows except those where Category = "B"

C. The report filters to show only rows where Category = "B"

D. The report shows an error because dropdown slicers can't filter text

Solution

1. Step 1: Understand dropdown slicer behavior

   Dropdown slicers filter the report to show only the selected value(s) from the column.

2. Step 2: Apply selection "B" to filter

   Selecting "B" filters the data to rows where Category equals "B" only.

3. Final Answer:

   The report filters to show only rows where Category = "B" -> Option C

4. Quick Check:

   Dropdown slicer selection = Filtered data [OK]

Hint: Dropdown slicer shows only selected value's data [OK]

Common Mistakes:

• Thinking it excludes selected value
• Assuming it filters blanks
• Believing dropdown slicers can't filter text

4.

You created a between slicer on a numeric "Sales" column but it shows no slider or range. What is the likely problem?

medium

A. Between slicers only work on date columns

B. The "Sales" column is stored as text, not numeric

C. The report page is filtered to zero rows

D. The slicer type is set to dropdown instead of between

Solution

1. Step 1: Check data type for between slicer

   Between slicers require numeric or date data types to show a range slider.

2. Step 2: Identify issue with "Sales" column

   If "Sales" is text, the slicer cannot create a numeric range slider, causing no slider to appear.

3. Final Answer:

   The "Sales" column is stored as text, not numeric -> Option B

4. Quick Check:

   Between slicer needs numeric/date type [OK]

Hint: Check column data type if between slicer shows no slider [OK]

Common Mistakes:

• Assuming between slicers only work on dates
• Not verifying slicer type setting
• Ignoring data type mismatch

5.

You want users to select multiple product categories but keep the slicer compact in the report. Which slicer type and setting should you choose?

hard

A. Dropdown slicer with multi-select enabled and single select off

B. Between slicer on the category column

C. List slicer with multi-select enabled and single select off

D. List slicer with single select enabled

Solution

1. Step 1: Understand slicer types for multi-select and compactness

   Dropdown slicers take less space than list slicers and support multi-select when single select is off.

2. Step 2: Evaluate options for multi-select and compactness

   List slicers with multi-select are larger; between slicers don't apply to categories; single select disables multi-select.

3. Final Answer:

   Dropdown slicer with multi-select enabled and single select off -> Option A

4. Quick Check:

   Compact multi-select = Dropdown slicer [OK]

Hint: Use dropdown slicer with multi-select enabled and single select off for compact multiple picks [OK]

Common Mistakes:

• Choosing list slicer for compactness
• Using between slicer on text categories
• Enabling single select disables multi-select
