2. Set “Variable type” to “Chemical parameters” Conductivity calculated for geothermal fluid at 72°C Electrical conductivity can be calculated by the new USGS method from 0 - 95°C and up to 1 molal ionic strength. The APHA method used in GWB10 and earlier, by contrast, was limited to 20-30°C and.5 molal ionic strength.

3. New in GWB11, any special plot can plot multiple samples. Schoeller diagram plots multiple lines together. Stiff, Radial, Bar charts, and Pie charts plot side-by-side. XY, Series, Time Series, Ternary, Piper, and Durov diagrams plot multiple markers together.

4. You control which samples are displayed from the Samples pane of that plot’s Configuration Dialog. Only selected samples in the Available list plot. You can cycle through samples one at a time. Plot all samples together.

5. Use Block, Next block to cycle through groups of samples. You set the number in the group on the Plot pane. You can quickly cycle from one Block of samples to the next. You can set Blocks for Schoeller, Stiff, Radial, Bar charts, and Pie charts.

6. New in GWB11, you can control details of the Stiff, Radial, and Schoeller Diagrams You can add cations, like Fe ++, or anions to the default plot. Use Up/ Down to reorder.

7. You can remove all the default analytes and replace them with others, including uncharged species. Use Up/ Down to reorder. Use non-electrical equivalent units to plot uncharged species, like organic compounds. By default, the Radial plot shows major cations and anions in electrical equivalent units.
