Excel scatterplot needs basic formatting

I have a few data results that I need formatting for my scatterplot. I have done it myself, but I'm having some issues. I want the data on the x axis to be logarithmically transformed, which I have done, and I need the first data point to start further away from 0 on the x axis. Secondly, I need a curvilinear line to go across the data points, and lastly I need the standard deviations to be bigger while keeping the same values.

Attached is what the graph looks like at the moment and another graph that shows what I'm looking for.
