Can you programatically create charts?

[Philip Allwright]

Is it possible to programatically create charts in Xamarin Forms?

In particular I want to create a bar chart that has between 1-30 data groups and in each group there can be up to 8 items.

e.g. The X axis could show classrooms (1-30), for each class room there are 1-8 timeslots, and the numeric Y axis would show student numbers.

Doing this in xaml is possible but messy. I had a quick look but couldnt see how to set up the series programtically.

 

Is this  possible and if so can you supply an example please.

Thanks

Hi Philip,

Yes,  you can create a chart programmatically.  An example can be found here. 

Here is a sample chart definition using C#: 

var chart = new RadCartesianChart
{
    HorizontalAxis = new CategoricalAxis(),
    VerticalAxis = new NumericalAxis(),
    BindingContext = new ViewModel()
};

var series = new BarSeries();

series.SetBinding(ChartSeries.ItemsSourceProperty, new Binding("Data"));

series.ValueBinding = new PropertyNameDataPointBinding { PropertyName = "Value" };
series.CategoryBinding = new PropertyNameDataPointBinding { PropertyName = "Category" };

chart.Series.Add(series);

For more chart examples check our SDK application: https://docs.telerik.com/devtools/xamarin/demos-and-sample-apps/sdk-browser-overview#sdk-browser-application.
