Logger Pro Power User Features

Are you looking for ways to expand your use of Logger Pro? Here are tips to get you started with some of the advanced features of our powerful data-collection and analysis software:

  1. Add multiple pages within a single Logger Pro file to organize graphs, data tables, pictures, and other information. All pages share the same underlying data and data-collection settings. See the Page menu for options.
  2. Combine data from several files into one by choosing Import from ▶ Logger Pro File from the File menu. You can use this feature to easily compare data from multiple groups.
  3. Choose Strike Through Data Cells from the Edit menu to temporarily ignore some data points. This is a great way to remove selected data from graphs or curve fits without actually deleting the values. The values are shown with a line through them in the data table. The feature can be used to ignore preliminary motion detector data, for example.
  4. When the graph is selected, you can use the spacebar to start or stop data collection. No more hunting for the Collect button.
  5. Draw predictions before doing experiments. To do this, choose Draw Prediction from the Analyze menu.
  6. Add a second vertical axis to display data of incommensurate units on the same graph. For example, graph pH and the derivative of pH on a single graph. Choose Graph Options from the Options menu to enable and configure a second y-axis.
  7. Choose Model from the Analyze menu to plot functions on a graph; then, adjust the parameters in the function helper object by selecting the parameter and using the arrow keys or by selecting the value of the parameter and entering values by typing on the keyboard or using cursor keys. Use this feature to have students find their own best-fit line and then compare it to the least-squares fit.
  8. Use calculated columns to display inferred quantities, even during data collection. For example, graph kinetic energy using a calculated column of 1/2 mv2 from the Motion Detector velocity data. Use a user parameter for m while you’re at it, and then add a parameter control for m using the Insert menu.
  9. Show error bars on a graph; error bars can be a fixed fraction, fixed value, or independently entered values. Enable error bars by choosing Column Options from the Data menu.
  10. Create a semi-log or log-log graph by choosing Graph Options from the Options menu.
