You will most likely have to read it in line by line and process and convert
the fields to build a data array, except in the simplest of cases: if the
first field (I assume you meant hrs:min) will be used as a data label, and you
want something like a lines plot from all of the remaining fields. That would
be 9 data sets, 9 lines, but all plotted to the same scale. That is probably
not what you want.
It isn't hard to read and process it. This example builds a data array with
the first field as a label and 10th field as a value, for a single line or bar
plot:
With a little more work, you could decode the hrs:min field and convert it to
a time value. This would be useful if the samples are not at uniform intervals
and you want to see that in the graph.

My weather station creates a csv file like
22:10,281,44,55,66,77,88,99,00,1010.9
which is basically an APRS weather string with some math done on the last
field of Baro Pressure. The first field is time in hes:min
Is there a way to read that into my php code and only use certain fields or do
I have to make an array from the array?
