1. I want to always appear on the vertical axis the range of 1E-08 to 1E0
The code we provided was meant to serve as a guide, so that you can create a solution that serves your purposes. You should be able to achieve the desired effect by setting the range of the axis. The code we sent previously should take the actual range of the axis in mind and build up the annotations.
2. when I apply Zoom, labels are moved
I apologize for not seeing it before, but you are using zooming so I think that we should use a different approach. I think it would be easier not to use annotations, but use custom elements outside the chart. I have attached a modified version of the previous project to demonstrate one way to achieve this with the conversion api of the chart. Please note that this is not meant to be the final code in your actual application, but a guide to help you implement the solution you require.
Again I would like to apologize for the inconvenience. Let us know if you have any additional questions.
