Thanks Tony, no real surprises, particularly after scaling the observation counts.
It is rather difficult to estimate the range for the x-axis values. Presumably the number of users in each range is cumulative over the range, and not just for the representative label value. The graph would be clearer if you could label the ranges on the x-axis as between bounds rather than an approximately central value.
Do you have the raw numbers easily available?

Each bin is to the next level. The x-axis legend is taken from the binning intervals, so it is difficult to change them ..

Yes, I have the data, it is from the backup data dump I get each month. Your question is stored as a query so easy to redo or reconfigure or regraph ...

So ask!

Can you do a log/log plot?

half log OK?

logarithmic x axis would be interesting

but log/log might give an approximate line and we could see if the slope varies over time.
