Error Bars and Reference Lines
Sometimes additional context is critical to help individuals understand the data in a visualization. For example, it might be important to know what the possible variation in values is, or how the actual values compare to what the expected target was. To help you add more information to your visualizations, in data.iowa.gov's new visualization canvas you can now add error bars and reference lines to your charts.
Error bars can be added from fields in your data to any column or bar chart, and reference lines can be easily added through the chart configurations to any bar, column, line, or histogram chart.
