DesktopChart how to fix Y scale and decimal value

I’m new to DesktopChart, and have taken a look at the Desktop Chart example, but still have so many questions.

Q1: Can you set a fixed Min-Max value for a LineChart to prevent auto-scaling?
Q2: Can you create a horizontal grid, to mark increments in the X-axis?
Q3: Can the double values display using formatting? (e.g. x.0, x.00, x.000)

I should add, I’ve been using “ChartView” from Jeremie Leroy for a couple years with great success. I’d like to start new projects with the native XOJO DesktopChart just to ensure future support, but it does have a learning curve.
