Assign dynamic data to series

[Devesh]

Hi,

I am trying to assign dynamic data to series which is coming from some database. But it seems, there is some issue which i am not able to figure it out.

Here is my code. Please look into it.

for (var i = 0; i < serieslist.Count; i++) {

     List<SeriesAttributeModel> ChartData = new List<SeriesAttributeModel>();

     ChartData = (serieslist[i] as SeriesModel).SeriesData;

     ColumnSeries Series = new ColumnSeries();

     Series.SetBinding(ChartSeries.ItemsSourceProperty, "ChartData");

     Series.XBindingPath = "Month";

     Series.YBindingPath = "Count";

     Series.EnableAnimation = true;

     Series.AnimationDuration = 1.0;

     Series.EnableTooltip = true;

     Series.EnableDataPointSelection = true;

     Series.DataMarker = new ChartDataMarker();

     Series.LegendIcon = ChartLegendIcon.Circle;

     Series.Label = "ABC";

}

Note: serieslist - it's a list of all series with chart data.

I am getting a blank screen with primary and secondary axis only. You can check it in attachement.

Please let me know, what is the issue ?

Also i want to know, does SfChart supports annotations ?

Instead of 

Series.SetBinding(ChartSeries.ItemsSourceProperty, "ChartData");

Try this, 

Series.ItemsSource = "Your data list";

It's working for me.

Hi Devesh,

Query 1 :“Issue in dynamic data to series”

You can resolve this issue by replacing following code snippet 

  

List<SeriesAttributeModel> ChartData {get; set;} 

ChartData = new List<SeriesAttributeModel>(); 

 

 Query 2 :“Annotations in SfChart”

Currently, we don’t have support for annotation in SfChart. We will consider this as future request and it will be available in any of our upcoming release.

Thanks for your reply. But for the query 1, i have already posted one solution.

The solution which you have given, i have already done that, but it's not working. Please check my code which i have shared.

Hi Devesh,

In your previous code snippet, you have declared ChartData as field instead of property. We have modified the sample for this and attached for your reference.

Please check and let us know if your issue is different from this.

Hi Divya,

I have already tried with the new approach which you have mentioned. But when i assign ChartData with dynamic data, currently it's static, it's shows a blank chart.

Anyways, the solution which i have provided, it's working with dynamic data also.

Many thanks for your support.
