Daily Revenue Bar or Line Graph

In the X axis you need either column of type date (so 2021-10-01, 2021-11-01, etc.) or 2 columns for month & day, with the visual drilled down to the lowest level. Otherwise it treats day = 1 as a single datapoint, regardless of the month
Another thing is that in your reference chart the values seem to be cumulative, while in the barchart they're individual data points. You can right click on the measure and use 'New quick measure' functionality:

Alternatively you can add sample tables (in format that can be copied to PowerBI) from your model with anonymised data (lke below) and we can write the running total manually.
