Define Bars panel with values as a data source enabled

The curve list displays the names of all the bar charts in the active window.  The Cut, Copy, Paste, and Add buttons under the bar chart list are used to maintain the bar chart list for the active window.  Bar charts can be copied and pasted into other bar chart windows or within the current bar chart window.  Bar charts can be also be added and deleted from the list, and they can be renamed.

Individual bar charts can be turned on or off.  To turn a bar chart off, select the bar chart from the window and deactivate the Series check box next to the bar chart name.  To turn a bar chart on that was turned off, activate the Series check box.

Bar charts are comprised of data and categories.  Data can be read from an external file, defined as a mathematical expression, or entered as values.  A label identifies categories and tic marks are used to separate them from other categories.  If there are more data points than there are categories, the application adds blank categories to accommodate the extra data points.
