Logger Pro Graphing Instructions
Follow these instructions to enter data into Logger Pro
1. Open Logger Pro on the Desktop.
2. Double-click on the “X” in the Data Set window.
3. In the box labeled “Name”, change the name to match the variable of the data column on your worksheet.
Change the “Short Name” to the symbol for that variable. Enter the correct units in the box labeled “Units”.
4. Click “Done”.
5. Repeat Steps 2-4 for the column labeled “Y” in the Data Set window.
6. Click in the box in the left-hand column of the Data Set window in Row 1 and begin entering data according
to your worksheet.
7. Right-click on the Graph window and select “Graph Options”.
8. Enter a title for your graph (usually “Dependent vs. Independent”), and then click “Done”.
9. Right-click on the Graph window again and select “Autoscale” -> “Autoscale from 0”.
Follow these instructions when a graph needs to be straightened because it is NOT linear
1. Click “Data” pull-down menu and select “New Calculated Column...”.
2. Change the name of the calculated column so that it is the name of your modified variable, as well as the short
name and units.
3. Select the variable you wish to modify from the pull-down menu labeled “Variables (Columns)” (below the
equation box), then type necessary math operations and click “Done”. You should now notice a new column,
already completed in your Data Set window (you may have to scroll to the right).
4. Click “Insert” pull-down menu and select “Graph”. Left click on the
dependent variable on the graph and select the appropriate variable from
the menu. Repeat for the independent variable.
5. To automatically arrange your page, click Ctrl+R.
6. Click the new graph to make it active, auto-scale from 0, then click the “Linear Fit” button on the toolbar (see
above).
7. If the Linear Fit matches the graph, use the data in the box to write a slope-intercept equation, substituting the
m-value for the slope and the b-value for the y-intercept.
Follow these instructions when a graph is linear
1. Click on the “Linear Fit” button in the toolbar.
2. If the Linear Fit matches the graph, use the data in the box to write a slope-intercept equation, substituting the
m-value for the slope and the b-value for the y-intercept. Include units.
m-value or slope
b-value or y-intercept
