A possible workaround is to manually set the MajorStepUnit and the MajorStep properties according to your setup.

Edit: Avalable in R3 2017 SP release.

Bars are too thin in iOS when items are per day.

If the series is added after the page constructor, the vertical axis labels are not shown.

As a workaround, create the series in the constructor and set its ItemsSource at a later stage.

Series labels are not displayed for horizontal BarSeries in UWP.

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.

DateTimeContinuousAxis displays incorrect labels when MajorStepUnit is Month. There are two labels for some months with 31 days.

If you have BarSeries with CombineMode set to "Stack" with zero values, the bars are placed to the maximum of the y-axis. 
As a work-around, you would need to manually adjust the Maximum value of the vertical axis.

Available in the 2018 R2 SP release.

Available in the R3 2018 SP release.

Ability to set a custom Trackball details DataTemplate. This would allow for two scenarios:

- Custom Styling
- Show other values alongside data point values

If we have a Chart with combined barseries and lineseries, and the lineseries is added first, the bars are misaligned - they are not placed in the center of the axis label on Android.

As a workaround, make sure to add first the barseries, then the lineseries.
