Bar Chart

lowcodera Bar Chart Component

Purpose

‌Bar charts are typically used to compare several categories of data. Bar charts are ideal for visualizing the distribution or proportion of data items when there are more than three categories‌.

Variations

‌There are several variations of bar charts which are supported through configuration of data and component properties.

• Basic Bar Chart

• Grouped Bar Chart

• Stacked Bar Chart

• 100% Stacked Bar Chart

• Reversed Bar Chart

• Bar Chart with markers

• Image background Bar Chart

​Working with Data

‌The data format for the bar chart is the same as for other XY charts. You can bind your chart component's items property to a Power Apps collection which includes either static data or dynamic data e.g. SharePoint.

Static Collection Example

In this example, a collection with static data called colBarChart is defined in the Power App. The items property of the bar chart component is then bound to this collection.

Table(
    {
        name: "Population",
        data: [
            {
                label: "South Korea",
                value: 400
            },
            {
                label: "Canada",
                value: 430
            },
            {
                label: "United Kingdom",
                value: 448
            },
            {
                label: "Netherlands",
                value: 500
            },
            {
                label: "Italy",
                value: 700
            },
            {
                label: "France",
                value: 1100
            },
            {
                label: "Japan",
                value: 1500
            },
            {
                label: "United States",
                value: 1456
            },
            {
                label: "Germany",
                value: 1700
            }
        ]
    }
)

The above code snippet will generate the following bar chart.

Dynamic Collection Example

The below example represents, Dataverse table's data in a dynamic manner. The dataverse table structure looks like below:

The below code snippet will generate dynamic collection to be consumed by component.

Table(
    {
        name: "Population",
        data: ForAll(
        //Replace Populations with the name of your datasource
            Populations,
            {
                Value: {
                    label: ThisRecord.Country,
                    value: ThisRecord.'Population (cr375_population)'
                }
            }
        )
    }
)
