WEBVTT 00:00:05.880 --> 00:00:11.230 When doing an experiment in Logger Pro, the action happens primarily in the graph. 00:00:11.230 --> 00:00:15.360 When you collect data, that data is recorded to the data table, and is plotted 00:00:15.360 --> 00:00:19.920 in real time. Seeing the graph being drawn while you observe some scientific 00:00:19.920 --> 00:00:25.170 principle, is a wonderful experience and a powerful learning tool. In this video, 00:00:25.170 --> 00:00:29.380 I'll show how to use the graph options to better tailor your graphs to illustrate 00:00:29.380 --> 00:00:34.320 the scientific principles in your lab. The data collected here was part of the lab 00:00:34.320 --> 00:00:38.830 "Newton's Second Law," from Physics with Vernier. In this lab, I connected a 00:00:38.830 --> 00:00:43.640 Dual-Range Force Sensor, an accelerometer, to a dynamics cart. I held onto the force 00:00:43.640 --> 00:00:48.700 sensor and wiggled the cart back and forth. Logger Pro recorded both the force 00:00:48.700 --> 00:00:54.190 and acceleration data. Netwon's Second Law's relationship between force and 00:00:54.190 --> 00:00:59.160 acceleration. By default, Logger Pro has recorded these quantities with respect to 00:00:59.160 --> 00:01:04.670 time. But since I have data for both, recorded simultaneously, I can choose to 00:01:04.670 --> 00:01:10.150 plot force versus acceleration. I can choose what is plotted on each axis by 00:01:10.150 --> 00:01:17.915 clicking on the axis title. I'll change the horizontal axis to plot acceleration. 00:01:26.266 --> 00:01:29.660 The relationship between force and acceleration looks pretty linear, so 00:01:29.660 --> 00:01:37.630 I'll do a quick linear fit. I can make further changes in the Graph 00:01:37.630 --> 00:01:42.210 Options menu. You can find the Graph Options menu either by right-clicking on 00:01:42.210 --> 00:01:52.680 the graph, or by selecting it and going to the Options menu above. First, I can add 00:01:52.680 --> 00:02:05.820 a title to the graph. By default, Logger Pro connects one data point to the next. 00:02:05.820 --> 00:02:10.580 If you'd like to turn that option off, uncheck this box here. For this force 00:02:10.580 --> 00:02:15.480 versus acceleration graph, it makes more sense not to connect the data points. In 00:02:15.480 --> 00:02:19.090 this menu there are lots of other options here to change how the data points are 00:02:19.090 --> 00:02:27.650 plotted, how the grid looks and other graph details. Now that I have the graph 00:02:27.650 --> 00:02:32.980 set up how I like, I can collect another run of data in the same graph. In fact, 00:02:32.980 --> 00:02:41.710 you can set up the graph options before or after data collection. Using the graph 00:02:41.710 --> 00:02:45.530 options is an easy way to tailor your graph to better illustrate the scientific 00:02:45.530 --> 00:02:51.040 principles in your experiment. Look for more video tutorials to get the most out 00:02:51.040 --> 00:02:52.500 of Logger Pro.
