Hi Eric,
Thanks for the sample.
1. Please find attached the sample which uses IChartAxisLabelModel to display the labels in Y axis. While doing so please be sure that the Indexed property of the Chart is set to true.
2. You can have the secondary axis at the desired position by creating a new instance of the Chart Axis class. Kindly have a look at the ChartMultipleAxes sample under [Installed Drive]:\Program Files\Syncfusion\Essential Studio\version number\Windows\Chart.Windows\Samples\ChartAxes\ChartMultipleAxesSample to have a better idea about this feature.
