LabQuest App

The Table menu allows you to create, modify, or delete 
columns of data. Anything in columns can be graphed. 
The following tools are available from the Analyze 
menu: 



 

 –New Manual Column 

creates an empty column into which you can 
enter or generate values directly. Tip: To make a 
graph of data from other sources, enter values in two manual columns, and then plot 
them in a LabQuest graph. 

 



 

 –New Calculated 

Column creates a new column whose values are 
based on other columns by a mathematical 
formula. Tap the Name field to enter a name for 
the new column, tap the units field to enter the 
units, then tap the Equation Type field and 
choose an equation for the calculations in this 
column. For example, you might define a 
calculated column as the inverse square of 
another column. After creating a calculated 
column, you can display the calculated data on a graph, or manipulate it further with 
additional calculated columns. 

 



 

 – This allows you to access the fields for setting the column name, 

units, and displayed precision. Alternatively, you can access these fields by simply 
tapping on the column name from the Table screen. 

 



 

 – This allows you to delete a manual or calculated column of data. 

Note that you cannot delete data collected from a sensor; however, you can hide data 
using the 

 tool. 

 



 

If you have stored at least one run using the 

 tool, this option will 

be selectable from the Table menu. Upon choosing Delete Run, tap the desired run name 
to delete the run. You will not be able to delete the last run created.

 



 

 – This action will clear all data in the table. Upon choosing this option, you 

will be prompted to confirm. 

 



 

Strike Through Data and Restore Data

 – Use these tools to ignore/restore selected data. 

Struck data are ignored for analysis and graphing, and the graph will update accordingly. 
To restore all data, tap the Table menu and choose Restore Data. Note that you can also 
access these tools from the graph screen by tapping on the Graph menu. 

 



 

 – Use this tool to tag a data point with a comment. After selecting the point 

within the table and tapping Tag Data, a circle will be displayed on the graph screen to 

“tag” the data. To add a comment, tap to select the Graph tab, locate the tagged point and 
tap to place the Examine cursor at this point. Then tap the info box at the right and enter a 
comment into the blank field.
