Overview

The Blazor Sparkline Charts is a replacement for normal charts to display trends in a very small area. Customize sparklines completely by changing the series or axis type and by adding markers, data labels, range bands, and more.


Sparkline types

There are five types of Blazor Sparklines (line, column, area, win-loss, and pie) to show data trends.

Line sparkline

Use a line sparkline to represent patterns and trends in data, such as seasonal increases or decreases, large changes, and a trend over a period of time.

Area sparkline

An area sparkline is a line sparkline with the area between its points colored. Use this when the magnitude of the trend is to be communicated rather than individual data values.

Column sparkline

A column sparkline is designed to show different values of two or more subjects. Vertical bars represent the different values.

Win-loss sparkline

A win-loss sparkline shows positive, negative, or zero values to visualize win/loss scenarios such as sports teams and stock prices.

Blazor sparkline chart rendered in pie type.

Pie sparkline

A pie sparkline is a circular graph that is divided into slices to illustrate numeric proportions.


Axis value types

The Blazor Sparkline Charts component offers different axis types like numeric, category, and date-time to plot any type of data in the sparkline.


Axis customization

Configure and customize the axis in Blazor Sparkline charts to show the origin and range of the data points.

Special points customization

Some data points in the sparklines are special. Denote the data usage by highlighting and customizing the special data points, such as first, last, high, low, and negative points.

Markers

The markers highlight and distinguish data points in the line and area sparklines and make these sparklines more readable.

Data label

Improve readability by using data labels in the Blazor Sparkline to display the values of data points.

Range band

Highlight a particular region in a sparkline using a range band to show the range of safe values. By setting the minimum and maximum for a range band, the outliers can be easily identified.

A single developer license for the Syncfusion Essential Studio for Blazor suite costs $995.00 USD, including one year of support and updates.

No, our 80+ Blazor components, including Sparkline Chart, are not sold individually, only as a single package. However, we have competitively priced the product so it only costs a little bit more than what some other vendors charge for their Sparkline Chart alone. We have also found that, in our experience, our customers usually start off using one of our products and then expand to several products quickly, so we felt it was best to offer all 80+ Blazor components for a flat fee of $995/developer. On top of this, we might be able to offer additional discounts based on currently active promotions. Please contact our sales team today to see if you qualify for any additional discounts.

No, this is a commercial product and requires a paid license. However, a free community license is also available for companies and individuals whose organizations have less than $1 million USD in annual gross revenue and five or fewer developers.

A good place to start would be our comprehensive getting started documentation.
