How to Create Power BI Visualization of Demand Depending on Weather

Our comprehensive guide on creating Power BI visualization is here to empower you. It demonstrates how changes in weather conditions influence demand patterns, providing you with valuable insights into consumer behavior. We're excited to walk you through the entire process, step by step, enabling you to effectively showcase and analyze the interplay between weather data and demand trends. By the end of this guide, you'll have gained the skills to develop a powerful Power BI report that's ready to seamlessly integrate into your website, enhancing your data-driven storytelling capabilities.

Demand Patterns and Weather Visualized in Power BI

Explore the complete process of crafting a Power BI visualization that uncovers the connection between demand patterns and weather conditions. Our detailed guide equips you with the tools to effectively analyze and visualize how weather influences consumer demand. This resource is designed to assist your Power BI assignment, providing valuable insights into data-driven decision-making.

Step 1: Data Preparation

Begin with two essential tables: one for weather data and another for demand data. Each table should include a "Date" column to enable seamless data integration.

Step 2: Loading Data

Load your data tables into Power BI using the Power Query Editor. Here's a code snippet to help:

```PowerQuery let Source = Folder.Files("C:\YourFolderPath"), #"Filtered Files" = Table.SelectRows(Source, each ([Extension] = ".csv")), #"Added Custom" = Table.AddColumn(#"Filtered Files", "Data", each Table.FromCsvFile([Folder Path] & "\" & [Name])), #"Expanded Data" = Table.ExpandTableColumn(#"Added Custom", "Data", {"Date", "Temperature", "Demand"}, {"Date", "Temperature", "Demand"}) in #"Expanded Data" ```

Step 3: Data Transformation

Create a new column to categorize weather conditions based on temperature. The code below demonstrates the process:

```PowerQuery let #"Added Weather Conditions" = Table.AddColumn(#"PreviousStepOutput", "WeatherCondition", each if [Temperature] > 25 then "Sunny" else if [Temperature] > 15 then "Cloudy" else "Rainy") in #"Added Weather Conditions" ```

Step 4: Data Modeling

In Power BI's Model view, establish relationships between the tables using the "Date" column.

Step 5: Creating Visualizations

Start by adding a "Table" visualization. Include columns: "Date," "Temperature," "Demand," and "WeatherCondition."

  • Next, create a "Line Chart" visualization:
  • Place "Date" in the "Axis" field.
  • Add "Demand" to the "Values" field.
  • Use "WeatherCondition" in the "Legend" field.

The line chart reveals demand shifts over time, each line representing a weather condition.

Step 6: Customizing the Report

Enhance the report's aesthetics by adding titles, adjusting colors, formatting axes, and incorporating more visuals.


With these meticulous steps completed, you've masterfully crafted a robust Power BI visualization that artfully uncovers the intricate interplay between demand fluctuations and weather conditions. This insightful report stands ready for effortless integration into your website, offering profound insights that can influence strategic decision-making. As you continue to refine and expand upon this foundation, remember that the potential for extracting valuable knowledge from your data is limitless.
