Volfix app - visualisation of the volume bars and time duration back

hello,

1. the Volfix Application shows 1 whole week which is to much, is it possible to change that into 1 day ? I only want to see 1 or maximum 2 days in the app.

2. the volume bars on the chart bottom are very very small with some kind of line or moving average in it - can I remove that line and make the volume bars bigger/ Higher to see them better ?

thanks
