Syncfusion Blazor Charts is a well-crafted charting component for visualizing data. It contains a rich gallery of 30+ charts and graphs, ranging from line to financial charts, that cater to all charting scenarios.
In this blog, we will go through the new features and improvements included in the Blazor Charts component for the 2022 Volume 1 release.
Area charts are mostly used to represent time-dependent data at equal intervals, showing the trends in the data. Now, you can add borders for these charts: area, spline area, step area, and stacking area.
Refer to the following code example.
<ChartSeriesCollection> <ChartSeries Type="ChartSeriesType.SplineArea"> <ChartSeriesBorder Width="2"></ChartSeriesBorder> </ChartSeries> <ChartSeries Type="ChartSeriesType.SplineArea"> <ChartSeriesBorder Width="2"></ChartSeriesBorder> </ChartSeries> </ChartSeriesCollection>
Markers are mainly used to represent data points with different shapes like circles, rectangles, triangles, or diamonds. Now, you can fill the marker for the data points with the series or data point’s color using the IsFilled property of the marker for the series.
Refer to the following code example.
<ChartSeries Type="ChartSeriesType.Line"> <ChartMarker Visible="true" IsFilled="true" Shape="ChartShape.Triangle"> </ChartMarker> </ChartSeries>
With 2022 Volume 1, you can easily customize the space between legend items in charts using the ItemPadding property.
The following code example shows how to do this.
<ChartLegendSettings ItemPadding="30"></ChartLegendSettings>
Instead of highlighting the series when hovering the cursor over both the legend and series, you can now set the chart to highlight the series only when hovering over the legend. This will be useful when you want to figure out the series corresponding to the legend item.
Refer to the following code example.
<ChartLegendSettings Enablehighlight="true"></ChartLegendSettings>
Now, the chart title will be placed near the pie and doughnut charts based on their radius. This will enhance the appearance of the charts.
In this 2022 Volume 1 release, we have improved the appearance of the tooltip and added an animation effect for a smooth transition while moving from one point to another in charts.

Keyboard accessibility is one of the most important aspects of web accessibility. Users with motor disabilities rely on the keyboard and many users prefer to use the keyboard for navigation to achieve better efficiency.
The Blazor Charts component now supports keyboard navigation, which allows you to interact with the chart elements easily using keys.
The Blazor Charts component supports the following keyboard shortcuts.
