When the chart has a lot of data, you may not necessarily want to show it all when the chart initially appears, but you may want to show the chart in a semi-zoomed state. Therefore, there should be properties which govern the ranges by which the chart should appear zoomed initially. So, the end-user should be able to zoom in/out starting from this state and then return to the same state if necessary (avoiding getting the whole data if he zooms out too much).
Allow easy exporting of a chart to a Xamarin.Forms image object. This will allow the images to be shared using social media.
Allow the user to customize the origin of rotation for axis labels.
Request for ranged series types. Here's an example of such a series type from UI for WPF http://docs.telerik.com/devtools/wpf/controls/radchartview/series/cartesianchart-series/bar-series/rangebarseries
Presently the trackball is displayed after a hold gesture. It will be a good addition to the features of the chart if the trackball can get displayed after a single tap.
I would like to have support for selecting a slice of the piechart from code-behind. I have have looked into the chart and series properties but found no selectable datapoints property. The chartSelectionBehavior offers a ClearSelection method and the readonly SelectedPoints property, but nothing to add a selected point.
Ability to set a custom Trackball details DataTemplate. This would allow for two scenarios: - Custom Styling - Show other values alongside data point values
Currently the labels are always positioned at the corresponding datapoint
Currently users could modify the visual appearance of the rendered axis labels, but cannot add a custom label at a specific location.
Currently, depending on the platform, the first piece of the pie is drawn at 3 or 9 o'clock. It should be possible for the developer to set the starting point to be 12 o'clock.
Currently the Annotation is always rendered on top of the series. Add a feature that will allow setting the series above the chart annotation.
Provide more control over the series rendering
