How to analyse a bar chart11/10/2022 ![]() ![]() ![]() Each series is represented by a different style of point. The main variables are X and Y variables. Scatter graphs display X-Y points as a scatter gram.Area is similar to a line, except that the area below the line contains a solid fill.Pie in which each series is represented by a circle, and each value of the main variable has a slice of the circle proportional to the value associated with it.This graph differs from the bar graph because adjacent bars represent equal ranges of the main variable. Each series creates an additional vertical bar at each point. Epi Curve use vertical bars to represent the count or weight for each value of the main variable.Each series creates an additional horizontal bar at each point. Bar graphs use horizontal bars to represent the count or weight of each value of the main variable(s).Each series results in an additional vertical bar at each point the bars are distinguished by their style. Column graphs use vertical bars to represent the count or weight for each value of the main variable(s).To generate a line graph with categorical data, generate a Bar graph and use customization. Each series is represented by a different style of line. The main variables are the X and Y variables. Line graphs connect X-Y points with lines.The following are the graph types capable of being generated by the GRAPH command along with type-specific information (“series” refers to the values of a main variable for a specific value of any crosstab and strata variables): To use a Multiline variable, define a new variable, assign to it the value SUBSTRING(,1,255), and use it in the graph. Multiline (memo) fields cannot be graphed. XTITLE=””, YTITLE=”” are used to pass X- and Y-axis labels from the GRAPH command.Uses the same coding scheme as the FORMAT function. DATEFORMAT=”” is used when a main variable is a date variable to determine the format in which it will be displayed.This title is in addition to the title for each graph, which is set by customization. TITLETEXT=”” represents a title for each page of graphs.Permissible AggFunc values are MIN (minimum), MAX (maximum), AVG (average), STDEV (standard deviation), SUM, SUMPCT (percent based on total of VarName), COUNT (number of records), or PERCENT (percent based on number of records). WEIGHTVAR=() allows multiple records referring to the same values of the main variable, crosstab variable (if any), and strata variable (if any) are represented by the aggregate of VarName.WEIGHTVAR= weights each record by the value of.However, if the sub-title is stratified (under “One Graph for Each Value of” in the dialog screen), it will be filtered out. When saving a template, the template stores the current graph’s background including the main title and the subtitle if it exists. STRATAVAR= generates a graph for each value of VarName.The represents one of the graph types described below.The represents a variable to be used to classify the main variable(s).The represents the (main) variable(s) to be graphed.This command produces graphs from data in Classic Analysis. ![]()
