JA Google Charts Axis Scale and Values

The values on the horizontal axis are rendered in double quotes. If this is intentional, how do I remove these quotes?
The area graph vertical axis automatically scales the values: 100, 120, 140. How do I set my own custom scale so I have the values in 5 units as follows: 100, 105, 110, 115, 120?

Please have a look at the screenshot attached.

No, by default, there are not double quotes there. Could you share the credentials of your site eg: URL, Admin + FTP account so I can take a look?
