General graph settings (SET)This section describes how to use the general graph settings screen to make thefollowing settings for each graph (GPH1, GPH2, GPH3).• Graph TypeThe initial default graph type setting for all the graphs is scatter graph. You can selectone of a variety of other statistical graph types for each graph.• ListThe initial default statistical data is List 1 for single-variable data, and List 1 and List2 for paired-variable data. You can specify which statistical data list you want to usefor x -data and y -data.• FrequencyNormally, each data item or data pair in the statistical data list is represented on agraph as a point. When you are working with a large number of data items however,this can cause problems because of the number of plot points on the graph. Whenthis happens, you can specify a frequency list that contains values indicating thenumber of instances (the frequency) of the data items in the corresponding cells ofthe lists you are using for x -data and y -data. Once you do this, only one point isplotted for the multiple data items, which makes the graph easier to read.• Mark TypeThis setting lets you specify the shape of the plot points on the graph.1 2 3 4
