Bar Plot


A bar plot is created by selecting Bar Plot from the New Plot Window command in the Plots menu, as shown.  



The Bar Plot set up dialog operates in exactly the same manner as the X-Y plot.  The only difference is that the Bar Plot provides a list of different bar types in place of a list of plot symbols.  


Note that all of the bar types except the solid bars are transparent so multiple bar plots can be produced to provide a 'stacked-bar' plot.   Strings can be plotted on the X-axis and then moved if necessary to provide labels for the bars.   The Professional version allows the selection of a column in the table containing string variables from the menu control below the Add point labels check box.  In this case, the labels associated with each point are set to the strings in the selected data column and they are plotted with the bars.  The labels can be moved to the desired locations.


The width of the bars is initially set to a default value, but it can be changed by moving the slider bar in the Symbol group box of the Modify Plot dialog (see below).  


The Professional version provides an option to create side-by-side bar plots when two or more bar plots are overlayed on the same set of axes.  To create a side-by-side bar plot, first plot two or more sets of data in a new bar plot.  Note that this can be done in one step by selecting two or more columns of data from the Y-axis list in the New Plot dialog and then selecting the Side-by-side bar plot check box, as shown 



Click OK and enter a caption for the Y-axis to create the plot.  The Side-by-side option can also be specified in the  Modify Plot dialog.



Note that the spacing between groups of bars can be changed with the slider control in the Symbol group box.
