Telerik UI for Blazor 2.1.0 is here and we are excited to share with you what’s new in the world of Blazor and UI for Blazor. A week ago, with the 2.0.0 release we announced Grid Hierarchy and DateTimePicker component, and this week we are extending the visual capabilities of the Telerik UI for Blazor suite with a refreshed Blazor demos page, three new chart series - Scatter, Scatter Line and Bubble Charts, and compatibility with the official release of .NET Core 3.0.

Blazing Fast Compatibility with ASP.NET Core 3.0 Official Release!

On September 23 Microsoft announced that .NET Core 3.0 is ready for use in production, and a couple of days later we were happy to announce that Telerik UI for Blazor is fully compatible with the official release of ASP.NET Core 3.0.

New Blazor Chart Components

Data is power and apps need compelling data visualization components to bring meaning and enable decision making for those that consume it. That’s why we made an effort to expand the data visualization options with three additional chart series – Scatter, Scatter Line and Bubble.

To create any of the charts described below, just follow these three easy steps:

  • Add a ChartSeries to the ChartSeriesItems collection
  • Set its Type property to ChartSeriesType.Scatter, ChartSeriesType.ScatterLine, or ChartSeriesType.Bubble depending on your selected visualization
  • Provide a data collection to its Data property, which contains numerical data for the X and Y axes (and, if applicable, for the bubble size)

*If you are new to UI for Blazor chart components, we suggest you head over to chart basics and data binding first.

New Blazor Scatter Chart

In its base form the Blazor Scatter chart is a two-dimensional data visualization that uses dots to represent the values of two different correlated variables - one plotted along the x-axis and the other plotted along the y-axis.

The code below produces a chart that shows the correlation of data between signal strength and errors per minute.

<TelerikChart>
    <ChartTitle Text="Unrecoverable Errors Per Minute vs. Signal Level"></ChartTitle>
    <ChartSeriesItems>
        <ChartSeries Type="ChartSeriesType.Scatter"
                     Data="@Series1Data"
                     Name="APSK modulation"
                     XField="@nameof(ModelData.Strength)"
                     YField="@nameof(ModelData.Errors)">
        </ChartSeries>
        <ChartSeries Type="ChartSeriesType.Scatter"
                     Data="@Series2Data"
                     Name="QAM modulation"
                     XField="@nameof(ModelData.Strength)"
                     YField="@nameof(ModelData.Errors)">
        </ChartSeries>
    </ChartSeriesItems>
    <ChartXAxes>
        <ChartXAxis Max="-30" AxisCrossingValue="@(new object[] { -100 })">
            <ChartXAxisTitle Text="Signal Strength, dBm"></ChartXAxisTitle>
        </ChartXAxis>
    </ChartXAxes>
    <ChartYAxes>
        <ChartYAxis>
            <ChartYAxisTitle Text="Error count"></ChartYAxisTitle>
        </ChartYAxis>
    </ChartYAxes>
</TelerikChart>

There are multiple scenarios with correlated values that can be represented using Scatter chart, for example:

  • Investments – compound interest
  • Income amount – expense amount
  • Hours of practice on an instrument – level of proficiency
  • Event exercise intensity – calories burned

New Blazor Scatter Line Charts

The Scatter Line chart is very similar to the Scatter chart - it adds a line which connects data points together. In this way, you can handle missing values, provide better visualization of the changes from point-to-point as well as good overall trend clarity of your data.

New Blazor Bubble Charts

In case you need to include a third dimension in your data visualization you can use the Blazor Bubble chart. By utilizing different sizes, colors and opacity you can allow deeper analysis and interpretation of your data.
