Web Components Line Chart

The Ignite UI for Web Components Line Chart or Line Graph is a type of category charts that show the continuous data values represented by points connected by straight line segments of one or more quantities over a period of time. It’s often used to show trends and perform comparative analysis. The Y-Axis (labels on left side) show a numeric value, while the X-Axis (bottom labels) show a time-series or comparison category. You can include one or more data sets to compare, which would render as multiple lines in the chart.

Web Components Line Chart Example

You can create the Web Components Line Chart in the IgcCategoryChartComponent control by binding your data to ItemsSource property and setting chartType property to Line enum, as shown in the example below.

Line Chart Recommendations

Are Web Components Line Charts right for your project?

• Different than an area chart, the line chart does not fill the area between the X-Axis (bottom axis) and the line.
• The Web Components line chart is identical to the Web Components spline chart in all aspects except that the line connecting data points does not have spline interpolation and smoothing for improved presentation of data.

A Line Chart includes several variants based on your data or how you want to tell the correct story with your data. These include:

• Layered Line Chart
• Stacked Line Chart
• Stepped Line Chart
• Polar Line Chart
• Stacked 100 Line Chart

Line Chart Use Cases

There are several common use cases for choosing a Line Chart:

• Have a large, high-volume data set that fits well with the chart interactions like Panning, Zooming and Drill-down.
• Need to compare the trends over time.
• Want to show the difference between 2 or more data series.
• Want to show cumulative part-to-whole comparisons of distinct categories.
• Need to show data trends for one or more categories for comparative analysis.
• Need to visualize detailed time-series data.

Line Chart Best Practices:

• Always start the Y-Axis (left or right axis) at 0 so data comparison is accurate.
• Order time-series data from left to right.
• Use visual attributes like solid lines to show a series of data.

When Not to Use Line Chart

• You have many (more than 7 or 10) series of data. Your goal is to ensure the chart is readable.
• Time-series data has similar values (data over the same period), it makes overlapped lines impossible to differentiate.

Line Chart Data Structure:

• The data source must be an array or a list of data items (for single series).
• The data source must be an array of arrays or a list of lists (for multiple series).
• The data source must contain at least one data item.
• All data items must contain at least one data column (string or date time).
• All data items must contain at least one numeric data column.

Web Components Line Chart with Single Series

The Web Components Line Chart is often used to show the change of value over time such as the amount of renewable electricity produced since 2009 over a ten-year period, as we have shown in the example below.

You can create this type of chart in the IgcCategoryChartComponent control by binding your data and setting the chartType property to Line, as shown in the example below:

Web Components Line Chart with Multiple Series

Since the Web Components Line Chart allows you to combine multiple series and compare or see how they change over time, let’s see how easy it is to achieve this. All we need to do is bind to a data source containing the data for China and the USA, and the line chart will automatically update to fit the additional data.

You can create this type of chart in the IgcCategoryChartComponent control by binding your data and setting the chartType property to Line, as shown in the example below:

Web Components Line Chart with Live Data

The Web Components Line chart is capable of handling high volumes of data, ranging into millions of data points, and updating them every few milliseconds as demonstrated in the following demo.

In this example, we are streaming live data into the Web Components Line Chart at an interval of your choosing. You can set the data points from 5,000 to 1 million and update the chart to optimize the scale based on the device you are rendering the chart on.

You can create this type of chart in the IgcCategoryChartComponent control by binding your data and setting the chartType property to Line, as shown in the example below:

EXAMPLE

DATA

TS

HTML

CSS

export class CategoryChartSharedData {

    public static generateItems(startValue: number, maxPoints: number, useShortLabels?: boolean): any[] {

        const data: any[] = [];
        let value = startValue;
        for (let i = 0; i <= maxPoints; i++) {
            value += Math.random() * 4.0 - 2.0;
            const v = Math.round(value);
            let l = i.toString();
            if (useShortLabels) {
                l = this.toShortString(i);
            }
            data.push({ Label: l, Value: v });
        }
        return data;
    }

    public static getTemperatures(startValue: number, startYear: number, endYear: number): any[] {
        const data: any[] = [];
        let value = startValue;
        for (let i = startYear; i <= endYear; i++) {
            value += (Math.random() - 0.5) * 0.5;
            const v = Math.abs(Math.round(value * 10) / 10);
            data.push({ Label: i.toString(), Value: v });
        }
        return data;
    }

        }
        return array[array.length - 1];
    }

    public static getNewItem(array: any[], index: number): any {
        const lastItem = this.getLastItem(array);
        const newValue = lastItem.Value + Math.random() * 4.0 - 2.0;
        return { Label: index.toString(), Value: newValue };
    }

        let roundValue: number;

        if (largeValue >= 1000000) {
            roundValue = Math.round(largeValue / 100000) / 10;
            return roundValue + "m";
        }
        if (largeValue >= 1000) {
            roundValue = Math.round(largeValue / 100) / 10;
            return roundValue + "k";
        }

        roundValue = Math.round(largeValue);
        return roundValue + "";
    }

Web Components Styling Line Chart

Once our chart is set up, we may want to make some further styling customizations such as change the line colors, change the legend font family, and/or increase the size of the axis labels to make it easier to read.

You can create this type of chart in the IgcCategoryChartComponent control by binding your data and setting the chartType property to Line, as shown in the example below:

You can also create a dashed line within the IgcLineSeriesComponent by using the IgcDataChartComponent and setting the dashArray property on the series. This property takes an array of numbers that will describe the length of the resulting dashes in the line.

The following example demonstrates usage of the dashArray in a IgcLineSeriesComponent in IgcDataChartComponent:

Advanced Types of Line Charts

The following sections explain more advanced types of Web Components Line Charts that can be created using the IgcDataChartComponent control instead of IgcCategoryChartComponent control with simplified API.

Web Components Stacked Line Chart

The Stacked Line Chart is often used to show the change of value over time such as the amount of renewable electricity produced for several years between regions. You can create this type of chart in the IgcDataChartComponent control by binding your data to a IgcStackedLineSeriesComponent, as shown in the example below:

Web Components Stacked 100% Line Chart

The Stacked 100% Line Chart is identical to the Stacked Line Chart in all aspects except in their treatment of the values on y-axis. Instead of presenting a direct representation of the data, the Stacked 100% Line Chart presents the data in terms of percent of the sum of all values in a data point. The example below shows a study made for online shopping traffic by departments via tablet, phone and personal computers.

You can create this type of chart in the IgcDataChartComponent control by binding your data to a IgcStacked100LineSeriesComponent, as shown in the example below:

Web Components Radial Line Chart

The Radial Line Chart belongs to a group of radial charts and has a shape of an unfilled polygon that is bound by a collection of straight lines connecting data points. This chart type uses the same concept of data plotting as the Line Chart, but wraps the data points around a circular axis rather than stretching them horizontally.

You can create this type of chart in the IgcDataChartComponent control by binding your data to a IgcRadialLineSeriesComponent, as shown in the example below:

Polar Line Charts use the same concepts of data plotting as the Scatter Line Chart with the difference that the visualization wraps data points around a circle rather than stretching them horizontally.
