If you re plotting pH you do not need a log scale since the pH is
the -log(H+ conc), so the log has already been taken,
Give us a few data points that you need to plot.
best wishes

I am trying to plot pH data in a scatter chart. I need to need to use log
scale for yaxis but cannot seem to figure out how to do the following.

1. cannot display minor gridline labels (since this is log scale...using
range of 1-10) how do I get the minor labels to appear?

2. how do I just show a subsection of this y-axis range without placing
the
x-axis in the middle of the chart? for example, if I set the x axis to
cross
at 5...then I still have the portion of the chart below 5 showing.
