See the attached screenshot.
I have a TKChart with a TKChartBarSeries. If I display the y axis to the right then it is missing the last label. Note that if I display it to the left (the default) it displays fine.
var categoryAxis = new TKChartCategoryAxis (objectCategories.ToArray ());
categoryAxis.Style.LabelStyle.Font = UIFont.BoldSystemFontOfSize(10);
categoryAxis.Style.LabelStyle.TextAlignment = TKChartAxisLabelAlignment.Right;
If necessary I can product a sample app but am hoping this is something you might be able to confirm. The version of TelerikUI is 2016.1.324.0.
