Bar charts can be used to show comparisons of data against targets and limits in either a vertical or horizontal chart.
You can compare only one specific set of data, where each bar represents the data, or you can cluster sets of data so that each specific set of data has its own bar, but the related sets are clustered and compared against other clustered data.
For example, this clustered bar chart shows 4 plants and 3 sets of data (clustered) for each plant: overall equipment effectiveness, downtime, and yield. In the same chart, you can see how downtime and yield affect the overall effectiveness of each plant, and how each plant compares against the others. The data is visualized in percentages.
Define Bar Chart Attributes
After you have created and configured some basic attributes for a chart, you can begin to design the “look” of the chart. Here, we show you the basic attributes that you need to set in order design a basic bar chart. To see all of the possible attributes you can configure, see Charts Attributes & Keywords Reference Guide.
Name X and Y Axes
Name the X and Y axes, as these labels will appear on the chart to identify the data represented. For example, the Downtime Bar Chart below shows Plant Downtime and Percent as the labels. You can see these labels in the chart above.
Select Query Chart Type
Here’s where you decide how you want to cluster data, or not.
Standard Bar Chart
Stacked Bar Chart
Clustered Bar Chart
Select Chart Orientation
Select Numbers & Unit of Measure Format
Use the pulldown menu to decide if the data information should be numbers, units of measure, or both.
Create & Name Bars
Now it’s time to add bars to your chart. You can add up to 20 bars.
Give a label to each bar or cluster of bars. For example, Bar 1 Name here is Plant 1.
Enter Values and/or Interface
Design Charts with Targets & Visualizations
You have the option to add targets and baselines to your chart to add more meaning to the data. For example, if you create a chart to show yield for manufacturing plants, you may set a baseline of minimum acceptable yield and a target for expected yield.
Set a Target and/or Baseline
Targets can be entered as values, or returned from an interface. To enter a value, use the Target column, otherwise use the Target Interface column to select a previously defined interface.
You can add up to 5 additional lines to each chart.
Note: Formulas and Functions can be used in the Target and Baseline attribute columns.
Give the Target a Name and Color
The Target Name, if you decide to use one, displays as a tooltip when you hover over the line in the chart.
Target Color adds color to the Target line. Use the pulldown menu to select a color.
Add Conditional Coloring
Conditional Coloring allows you to change the color of the bar above and below the Target line based on the value comparison.
Above Target Color and Below Target Color allow you to select those Conditional Colors, and you can name each in the Above and Below Target Name.
For example, if you set targets for performance, you can set the color to green above the target line and use Pass as an Above Target Name.
