How to Add Error Bars to Bar, Column and Line Charts

This article includes a customized template of a Bar, Column and Line Visualization (originally from Visualization > Bar/Column/Line), which can additionally show error bars.

Requirements

• A Displayr document.
• A standard table or R table that references a standard table. For summary tables, you must display Lower Confidence Interval (%) and Upper Confidence Interval (%) statistics in the cells. For crosstabs, you will need to apply the appropriate Rule from How to Calculate Confidence Intervals for Crosstabs with Numeric Variable Sets and How to Calculate Confidence Intervals for Crosstabs with Categorical Variable Sets and display Lower Confidence Interval and Upper Confidence Interval in your table.
• You wish to use a Bar, Column or Line chart and add error bars using Upper and Lower Confidence Intervals.
