Graph Setup Options

BHS -> Staff -> Mr. Stanbrough ->Pasco Interface Notes-> this page

The Graph Setup dialog will open: The options are:

• Name: You can type a new name for the graph, if you choose.
• Data Points: If this is not checked, data points won't be displayed. Is there a good reason to do that? If you don't show the data points, you must select "Connected Points" or "Bar Graph" to have anything displayed in the Graph Window.
• Connected Points: This is a "connect the dots" style graph. You will probably want to uncheck this one, for just about all physics graphs.
• Bar Graph: Displays the data as a bar graph - not generally useful for physics experiments.
• Grid: Show/hide the graph paper background.
• Point Protectors: Graphic elements that draw attention to the location of data points, which can sometimes be hard to see. Personal preference, here.
• Integral Histogram: This is used in conjunction with the Bar Graph.
• Auto-Scale During Sampling: If this option is checked, the graph will automatically rescale itself if a data point would fall outside of the current graph.
• Auto-Scale Time Axis: If this option is checked, the graph will automatically rescale itself if the time for a data point falls outside the current horizontal graph range.
• Error Bars: You can choose either horizontal or vertical error bars (or both). If the "%" box is checked, then the value in the "+/-" field is interpreted as a relative uncertainty, otherwise it is interpreted as an absolute uncertainty.
