What is the primary reference line for longitude?

The prime meridian is the line of 0 longitude, the starting point for measuring distance both east and west around the Earth. The prime meridian is arbitrary, meaning it could be chosen to be anywhere. Any line of longitude (a meridian) can serve as the 0 longitude line.

What is the reference line?

Reference Lines allow you to place lines on the plot at specific locations to mark important values. You could use these to mark control limits or to indicate a trend line for a set of data.

    What are the special lines of latitude?

    Several lines of latitude have special significance. One of these is the equator. Two other special lines of latitude are the 30th parallels. The area between them, straddling the equator, is commonly referred to as the low latitudes. The low latitudes are generally warm lands. The two 60th parallels are also special lines of latitude.
