RadChartView doesn't support center the position of its axis. To achieve such requirement you can hide the VerticalAxis and use annotation to draw a custom one in the center of the plot area. You can take a look at the following steps.
Use the Visibility or the ElementBrush property of the Axis to hide it.
Create a new CartesianGridLineAnnotation and position it at the center of the plot area. This will be the new axis line.
Decide (or calculate) how many labels you want to display on the axis and where. Then use CartesianCustomAnnotation to draw the ticks and the labels.
For your convenience, we have created sample project demonstrating the approach described above. Keep in mind that this custom code is not fully tested and we cannot guarantee that it will work properly in all expected scenarios. You can further test and modify the project to fit the desired scenario.
