Another question, the answer to "Stack Overflow", made me change the "Orthogonal Coordinate Decimal". For instance:
axisSet.xAxis.orthogonalCoordinateDecimal = CPTDecimalFromString(@"0")
This made my X axis go through the origin. To raise my X axis relative to my graph, I changed the value to "25000", as in:
axisSet.xAxis.orthogonalCoordinateDecimal = CPTDecimalFromString(@"25000")
, , - . 0 185 000, 25 000 4, 30 (, , ). 0-185 000 5,0 , , .
