Key points about plotting data sets

Once you understand these key points, it will be easy to control which data sets are graphed.

A graph can include many data sets from many tables. By default, Prism makes one graph per table. But you can plot the same data table on multiple graphs, and a single graph can have data from multiple tables.

When you fit a curve by nonlinear regression (or a line by linear regression) the best-fit line or curve is essentially a data set. Prism automatically plots the line or curve on a graph, but you can remove the curve from one graph, or plot it on other graphs. Treat the curves just as you would treat any other data sets.

When you transform or normalize data, the results appear on green data tables. You can't edit these tables, but the data sets on green data tables can be graphed like any other.

Data Sets on Graph tab of the Format Graph dialog

The second tab of the Format Graph dialog lets you add, remove and replace data sets on the graph (and also change the front-to-back or left-to right order of data sets).

Bring up the dialog by double clicking on the graph, or using a shortcut button.

Shortcuts for adding, replacing and removing data sets

You don't need to use the dialog to add or remove data sets.

Add data to a graph by dragging a data or results table from the Navigator and dropping it onto the graph.

Remove or replace a data set by right clicking on any point or bar, and choosing Remove Data Set or Replace Data Set.
