SfChart provides the following two properties to zoom the chart: ZoomFactor and ZoomPosition The ZoomFactor property defines the zooming level and the ZoomPosition property defines the zooming (scrolling) position for chart. Both values should fall between 0 and 1. For instance, when ZoomFactor is 0.5 and ZoomPosition is also set to 0.5 for the chart with 10 data points, it shows last 5 data points in chart. Here, ZoomFactor decides no of points (5), and ZoomPosition decides range of values to display (from 6 to 10). C#

In Android I was using ZoomFactor and Zoom position as value bound to my viewmodel and all seems to work.
In iOS seems that I need to set them via code behind, otherwise they don't work as expected.
Can you check it?
Thank you
