Vizualizing and Exploring Your Data

 

Using a Case Study where we start by exploring/investigating lots that fail the lower spec for dissolution, see how to:

 

  • Analyze one variable at a time, leveraging dynamic linking to scan for relationships and ID areas for data cleanup
  • Use Graph Builder to quickly explore data and switch between graph types easily
  • Use Fit Y by X to model relationship between 2 variables, produce various analysis report types based on data type and include some related statistics

 

Questions answered by Clark Ledbetter @Clark_Ledbetter and Mark Zwald @mzwald at the live webinar.

 

Q: How do I handle spec limits that are different for different rows of data?

A: See this JMP Community article by a JMP Developer:  Process specification limits that differ based on a grouping column . It goes over how to input multiple spec limits that differ based on a grouping column (ex: Supplier Name). It will then separate the capability analysis based off the grouping and the differing spec limits.

 

Q: How do you start recoding, like you did for Jones and Smith?

A: You can access the recode utility by right-clicking on the column name in the data table or from the Cols menu at the top.

 

Q:  How do you have the LSL (Lower Specification Limit) line shown?

A: Spec limits are handled by column properties in JMP. When you specify the spec limit column property, there is a check box option to show reference lines for the defined specs.

 

Q: Can we do caption box plots in JMP 15?

A: You can add captions by going to the Tools menu and select Annotate. You can use this to add captions to any JMP report.

 

Q: Is there a way to show spec lines by default on graphs? I have to manually do it each time.

A:  You can set a JMP Preference for this. Go to File > Preferences > Platforms > Manage Limits, and check the "Show Limits All" option.

 

Q: Explain what the normal quantile chart means please? Why is this important?

A: One use is it allows you to determine if your distribution is normally distributed if the normal quantile chart shows a linear relationship.

 

Bonus: Here are some related answers from Mark Zwald  @mzwald at a related JMP 16 session:

Q: How do you access column view selector?     

A: You can access column viewer from the Column menu.

 

Q: Does "recode" create a new column?

A: You can have it create a new column or have it recode in the existing column.

 

Q: When do I see Distribution Frequencies instead of Quantiles and Summary Statistics?

A: Frequencies are shown for columns with categorical modeling types, either nominal (red bars) or ordinal (green bars).  Continuous data (blue triangles) shows the quantiles and summary statistics.

 

Q: If replacing the existing column during recode, can i reverse it back later?

A: You can undo the recode to get back the existing values.  In general, it's good practice to make a new column so that you preserve the original values.

 

Q: Does LOCAL data filter mean it's only filtering in the window and not doing anything to the underlying data table?

A: Yes               

 

Q: Is there a way to keep range of graphs fixed during filter animation?

A: Yes, from the red triangle menu in graph builder, select the "Lock Scales" option.

 

Q: Can we capture Animation effect (in Local Data Filter) in a PowerPoint?           

A: In the windows version of JMP you can.  Select animation from the red triangle of the data filter.  Click the record button in the Local Data Filter, turn on the filter animation, then click stop and then save the result as a .gif file.  If you insert that .gif into PPT, it will animate when you present the slide.

Q: How can I make a graph with x-axis showing # of observations, y-axis showing accumulative # of sale representatives?

A: In addition to Nick's answer, there is a Cumulative Sum summary statistic available in Graph Builder when you make a Bar Chart.

 

Q: Can you display the number of data points for box plot on the Graph Builder Graph?

A: When you do a Oneway analysis from the Fit Y by X platform and turn on the "Means and Std Dev" option, you will see the number of observations in each categorical level.

 

Q: Can we group scripts on JMP data table for common categories?

A: Yes. Select the scripts you wish to group, right click and select Group Scripts.
