Need help interpreting the meteogram

[dkuchta5]

A couple of things elude me in the meteogram. There is a thin lin graph running through it, with no label. I suspect it may be the atmospheric pressure, but hard to tell.

The 2nd thing is the label at left that says "Clouds, rain in". I assume that means rain in inches, but directly below it is a rain icon labelled "Rain" in dark blue, and the rain amount appears to be indicated by a vertical blue bar on the days when rain is predicted. So if the blue label and bars are showing rainfall in inches, what is the "Clouds, rain in." label indicating?

Yes the thin line is the atmospheric pressure. Values of pression are just above.
Cloud, rain in. (or mm) is just a title.
Rain in blue is the non convective rain shown in blue as a bar graph, together with convective rain in pink, or snow in light blue. Values of these type of precipitation are shown above the bar graph.
