SFChart ColumnSeries not showing

[Andy]

Hi,

I have a StackLayout with a simple ColumnSeries chart in it. It displays an empty space. If I change the charttype to PieSeries or DoughnutSeries it works and the chart is shown. Why is the ColumnSeries type not showing?

XAML View:

...

             <chart:SfChart HeightRequest="300" WidthRequest="100" AreaBackgroundColor="Transparent">

                    <chart:ColumnSeries ItemsSource ="{Binding BeendeteArbeitsgaengeProDatum}"/>

                </chart:SfChart>

...

Model Binding:

      public ObservableCollection<ChartDataPoint> BeendeteArbeitsgaengeProDatum { get; set; }

        public DashboardViewModel()

        {

            BeendeteArbeitsgaengeProDatum = new ObservableCollection<ChartDataPoint>();

               ...

            foreach (var item in _response.BdeDashboard.BeendeteArbeitsgaengeProDatum)

            {

                   BeendeteArbeitsgaengeProDatum.Add(new ChartDataPoint(item.Key, Convert.ToDouble(item.Value)));

            }

        }

Hi Maria, 

 

Greetings from Syncfusion. 

 

We have analyzed the provided code snippet and found that you were missed to add the chart Axis for the chart. We would like to let you know that for Cartesian series it is mandatory to set the PrimaryAxis and SecondaryAxis for chart. Please refer the below code snippet for more details 

 

XAML: 

<chart:SfChart x:Name="chart" HorizontalOptions="FillAndExpand"   

                           VerticalOptions="FillAndExpand"> 

         <chart:SfChart.PrimaryAxis> 

                  <chart:CategoryAxis/> 

         </chart:SfChart.PrimaryAxis> 

         <chart:SfChart.SecondaryAxis> 

                  <chart:NumericalAxis/> 

         </chart:SfChart.SecondaryAxis> 

         <chart:ColumnSeries ItemsSource ="{Binding BeendeteArbeitsgaengeProDatum}"/> 

</chart:SfChart> 

 

 

Hope the above solution helps to resolve the reported issue.  

 

Note: Only for the accumulation series types like Pie and Doughnut series axis is not required and for all other cartesian series Axis needed.

Good morning,

thanks, it works now! 

I've only looked at the chart types code snippet in the documentation (https://help.syncfusion.com/xamarin/charts/charttypes#column-chart)

Have a good day

I spent more than an hour to find out why my chart was not working.

In the documentation I had found nothing about it. I think this information needs this in TOTAL HIGHLIGHT in the documentation.
