Input
XYRange
Specify the XY range to location the stiffs in a Stiff Map diagram]
Range
Specify the input ions Na. The unit of these input values are mg/L.
Specify the input ions K. The unit of these input values are mg/L.
Specify the input ions Ca. The unit of these input values are mg/L.
Specify the input ions Mg. The unit of these input values are mg/L.
Specify the input ions Cl. The unit of these input values are mg/L.
Specify the input ions HCO3. The unit of these input values are mg/L.
Specify the input ions CO3. The unit of these input values are mg/L.
Specify the input ions SO4. The unit of these input values are mg/L.
Specify the additional cations. The unit of these values are mg/L.
Specify the additional anions. The unit of these values are mg/L.
Conversion Factors is equal to ionic charge divided by molecular weight. The unit is Meq/mg.
Specify a column label row as group info for the ions. Select None means each column will be one point. If column A, B and F are one group, A and B are cations, F is anion, then A+B is one point in Cations and F is a point in Anions, and they are at same vertical position. If all 8 ions are selected to plot, and this control is set to None, Origin will use the system default grouping info, that is Na+K+Cl, Ca+HCO3+CO3 and Mg+SO4.
You can set a column to specify the sample ID to label the polygons.
