Problem:
If there exist empty cells in the selected data range, the PetroPlot program might hang up.
In the following example, trace element data are not complete.
Now we select a data range and run the PetroPlot "Multi-XY Plot" function
PetroPlot hangs up, gives only one series even we selected all data.
Solution:
Create two columns with sequential data.
Run the PetroPlot "Multi-XY Plot" function
Format the TempX vs TempY chart
Copy the TempX vs TempY chart to another place, and run "Change XY" function
The result.
