Bar and Pie Chart Control

The Bar and Pie Chart layout controls in BizzStream Aero provide powerful visualization tools to represent data effectively. These charts are essential for quickly understanding distributions, comparisons, and trends within your datasets. The chart within the layout allows consultants to configure and display both bar and pie charts, offering flexibility in data representation.

When to Use It

Bar Charts are ideal for:

• Comparing discrete categories: Easily compare values across different categories (e.g., sales per product, users per region).
• Tracking changes over time: Show trends or changes in a metric over specific periods (e.g., monthly revenue, quarterly expenses, user usage).

Pie Charts are best suited for:

• Showing proportions of a whole: Illustrate how different parts contribute to a total (e.g., market share, budget allocation).
• Highlighting dominant categories: Quickly identify which categories represent the largest portions of your data.

How to Start Using It

To start using the Bar and Pie Chart Control, you will need to:

• Access your Layout: To begin adding Bar and Pie Chart controls, navigate to the layout where you want to include them.
• Add the Chart Control: Locate the Bar Chart or Pie Chart control in the layout editor's toolbox and drag it onto your desired position within the layout.
• Configure Control Properties: Double-click the chart control in the layout, or by pressing the Edit button, then fill in the following properties:

Property	Required	Description
Aggregation Dataset	Yes	Select the dataset that contains the data you wish to aggregate and visualize. This dataset will be processed to generate the chart.
Value Field	Yes	Specify the field from your selected dataset that holds the numerical values to be aggregated and displayed on the chart (e.g., count, amount, total).
Item Label	Yes	Define the label for each bar or pie slice. This can be a static string or a dynamic BizzStream Expression that uses field values from your dataset. For example, {{F["unit"]}}:{{F["count"]}} would combine the value of the 'unit' and 'count' fields for each item.
Direction	No	(Bar Charts Only) Determines the orientation of the bars. Choose Horizontal for bars extending horizontally or Vertical for bars extending vertically. The default is Vertical.
Aspect Ratio	No	Sets the width-to-height ratio of the chart. Common values include 16:9, 4:3, or 1:1. If left empty, a default aspect ratio of 16:9 will be applied.

• Save the Changes: Don't forget to save the changes after setting the properties.

Example

How to start using these Bar and Pie charts? Underneath there will be an example for how to use each one of them to make them to fit the correct style and situation.

Bar example - Supplier overview

Let's say you want to see which suppliers your inventory's total value is coming from. A bar chart is a great way to do this. You can list each supplier and then use the length of the horizontal bar to represent the totalValue of all products from that supplier.

This gives you a clear visual of which suppliers you are spending the most money with. This insight can be crucial for negotiating better prices or managing relationships with your vendors. The chart below illustrates how you might see this data.

In this example, it's immediately clear that the first and last suppliers account for a large portion of your inventory's total value. By creating new charts over time, you can compare the values to see the impact different suppliers have on your inventory and spot trends as they emerge.

Pie example - Inventory Value

Let's consider a restaurant's inventory. You have different items, and you want to understand how much of your total inventory value is tied up in each product. A pie chart can be a great way to visualize this.

In this scenario, a simple count of items might be misleading, as a few expensive products could represent a large portion of your money. A pie chart can show you the percentage of total value for each item.

This pie chart clearly shows that the salami and cheese account for a large portion of the total inventory value. This kind of visualization can help a business owner identify where their money is heavily invested and where they might be able to find cost-saving opportunities.
