Input

XYRange

Specify the XY range to location the stiffs in a Stiff Map diagram]

Na na

Input

Range

<optional>

Specify the input ions Na. The unit of these input values are mg/L.

K k

Input

Range

<optional>

Specify the input ions K. The unit of these input values are mg/L.

Ca ca

Input

Range

<optional>

Specify the input ions Ca. The unit of these input values are mg/L.

Mg mg

Input

Range

<optional>

Specify the input ions Mg. The unit of these input values are mg/L.

Cl cl

Input

Range

<optional>

Specify the input ions Cl. The unit of these input values are mg/L.

HCO3 hco3

Input

Range

<optional>

Specify the input ions HCO3. The unit of these input values are mg/L.

co3 CO3

Input

Range

<optional>

Specify the input ions CO3. The unit of these input values are mg/L.

so4 SO4

Input

Range

<optional>

Specify the input ions SO4. The unit of these input values are mg/L.

Input

Range

<optional>

Specify the additional cations. The unit of these values are mg/L.

Input

Range

<optional>

Specify the additional anions. The unit of these values are mg/L.

Conversion Factors factor

Input

Range

<optional>

Conversion Factors is equal to ionic charge divided by molecular weight. The unit is Meq/mg.

• This option could be None if there is no additional ion, that means all the input ionic data has been multiplied by built-in conversion factor automatically. The plot data will be in the unit "Meq/L";
• If there is any additional ion, you are supposed to select the column label row filled with conversion factors. Then the plot data should be in the unit "Meq/L" gotten by Input Ionic(mg/l)*Conversion Factors(Meq/mg).
Group group

Input

Range

<optional>

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.

Sample ID samp

Input

Range

<optional>

You can set a column to specify the sample ID to label the polygons.
