The curve is defined, by default, as 150 line segments. If you plan to zoom in and plot only part of the curve On the dialog that pops up, choose to make one graph for each data set (in this context, a data set is a curve). If you want each curve to be on its on graph, go to the results table, find the "New" dropdown menu in the toolbar (looks like a green plus sign), and choose "New Graph of existing data.". Plotting each curve on a separate graphīy default, Prism will make graph that contains all of the curves on one graph. Then click on one curve at a time, and enter the value for the parameter that varies among curves. Often you'll want to first click "select all" and enter most of the parameters. Select one or more of these curves (or click "select all") and then enter the parameter values below. The top of the third tab lists all the curves you will generate. Put in front of a line that only applies to column A, etc. If you need to do something more complicated, remember you can write the equation so some lines only apply to certain data sets. The latter usually makes more sense and is easier. Specify on the bottom of the second (Options) tab whether you want to label each curve manually (enter the labels the top of the third tab) or you want each column labeled using the value of one of the parameters. You'll also want to label the columns of the computed table. Instead, define the values on the third tab. You'll want one parameter in the equation to vary from curve to curve. If you choose to plot more than one curve (a choice on the first tab), the rest of the dialog works a bit differently. Tips for plotting a function Plotting a family of curves On the third tab (Parameter values), enter the parameter values (or click the fish hook icon to hook analysis or info constants). There is little reason to change the default (150), unltess you want to plot only a portion of the curve on some graphs, in which case you should increase that value.Ĥ. You can choose the number of line segments that will define the curve. The "curve" is actually a set of X and Y coordinates that define a series of points that are connected to form the curve. On the second tab (Options), choose whether you also want to plot the first derivative, second derivative or integral of the function. On the first tab (Function), choose the equation, the starting and ending values of X, and the number of curves you want to plot.ģ. Start from any data table or graph, click Analyze, open the Generate Curve folder, and then select Plot a function. Rather it generates curves from an equation you choose and parameters you enter.ġ. Prism offers a Plot a function analysis, but it doesn't in fact analyze any data.
