How to create a graph with multiple axes using Blazor Chart?

This article explains how to add multiple Y axis in Blazor Chart

Blazor Chart with multiple Y axis

Blazor Charts provide a support to use multiple axis at a time by using ChartAxes.

The ChartAxes is a secondary axis collection that can be used to add “n” number of axes to the chart in addition to the basic X and Y axis. By mapping with the axis unique name, series can be linked to it.

In the below code example, the series and axis are linked together by using Name property of ChartAxis by providing same name for YAxisName property.

 <ChartAxes>
  <ChartAxis Name="YAxis" OpposedPosition="true"/>
 </ChartAxes>
 <ChartSeriesCollection>
    ...
    <ChartSeries YAxisName="YAxis" DataSource="@WeatherReports" XName="Month" YName="Product2" Fill="pink" >
    </ChartSeries>
</ChartSeriesCollection>

The following code snippet illustrates how to create graph with multiple Y axis.

Index.razor

@using Syncfusion.Blazor.Charts

<SfChart>

    <ChartPrimaryXAxis ValueType="Syncfusion.Blazor.Charts.ValueType.DateTime" Interval="1" IntervalType="IntervalType.Months">
        <ChartAxisMajorGridLines Width="0"/>
        <ChartAxisMinorGridLines Width="0"/>
    </ChartPrimaryXAxis>

    <ChartPrimaryYAxis>
        <ChartAxisMajorGridLines Width="0"/>
        <ChartAxisMinorGridLines Width="0"/>
    </ChartPrimaryYAxis>

    <ChartAxes>
        <ChartAxis Name="YAxis" OpposedPosition="true" Interval="10" Minimum="10" Maximum="50"/>
    </ChartAxes>

    <ChartSeriesCollection>
        <ChartSeries DataSource="@WeatherReports" XName="Month" YName="Product1" Type="ChartSeriesType.Spline" Fill="blue">
        </ChartSeries>
        <ChartSeries DataSource="@WeatherReports" XName="Month" YName="Product2" Type="ChartSeriesType.Spline" Fill="pink" YAxisName="YAxis">
        </ChartSeries>
    </ChartSeriesCollection>

</SfChart>

@code {

    public class Chart
    {
        public DateTime Month { get; set; }
        public double Product1 { get; set; }
        public double Product2 { get; set; }
    }

    public List<Chart> WeatherReports = new List<Chart>
    {
        new Chart { Month = new DateTime(2005, 01, 01), Product1 = 21, Product2 = 26 },
        new Chart { Month = new DateTime(2005, 02, 01), Product1 = 24, Product2 = 20 },
        new Chart { Month = new DateTime(2005, 03, 01), Product1 = 36, Product2 = 30 },
        new Chart { Month = new DateTime(2005, 04, 01), Product1 = 30, Product2 = 40 },
        new Chart { Month = new DateTime(2005, 05, 01), Product1 = 25, Product2 = 35 },
        new Chart { Month = new DateTime(2005, 06, 01), Product1 = 20, Product2 = 30 },
        new Chart { Month = new DateTime(2005, 07, 01), Product1 = 40, Product2 = 20 },
        new Chart { Month = new DateTime(2005, 08, 01), Product1 = 35, Product2 = 45 },
    };
}
