Line Chart | lowcodera

Line graphs are used to track changes over short and long periods of time. When smaller changes exist, line graphs are better to use than bar graphs. Line graphs can also be used to compare changes over the same period of time for more than one group.

Variations

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

Working with Data

‌The data format for the Line chart is the same as for other Lowcodera 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.

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

Table(
    {
        name: "Actual",
        data: ForAll([
            {
                label: 2001,
                value: 44
            },
            {
                label: 2002,
                value: 60
            },
            {
                label: 2003,
                value: 28
            },
            {
                label: 2004,
                value: 32
            },
            {
                label: 2005,
                value: 36
            },
            {
                label: 2006,
                value: 43
            },
            {
                label: 2007,
                value: 55
            },
            {
                label: 2008,
                value: 21
            }
        ],{Value: ThisRecord})
    },
    {
        name: "Budgeted",
        data: ForAll([
            {
                label: 2001,
                value: 25
            },
            {
                label: 2002,
                value: 42
            },
            {
                label: 2003,
                value: 50
            },
            {
                label: 2004,
                value: 18
            },
            {
                label: 2005,
                value: 17
            },
            {
                label: 2006,
                value: 19
            },
            {
                label: 2007,
                value: 58
            },
            {
                label: 2008,
                value: 35
            }
        ],{Value: ThisRecord})
    }
)

The above code snippet will generate the following line chart.

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: "Actual",
        data: ForAll(
            Finances,
            {
                Value: {
                    label: ThisRecord.Year,
                    value: ThisRecord.Actual
                }
            }
        )
    },
    {
        name: "Budgeted",
        data: ForAll(
            Finances,
            {
                Value: {
                    label: ThisRecord.Year,
                    value: ThisRecord.Budget
                }
            }
        )
    }
)

All control properties can be left as default
