Define a Value Bar Column for a Matrix Widget

Use the Columns page (in the Matrix Widget Properties window) to define how a value bar column looks and behaves on a Matrix Widget.

A value bar column displays a bar whose width represents a value. For example, display a value bar comparing the number of changes approved for each row.

Good to know:

• Calculated columns are calculated after all numeric columns have been retrieved.
• Calculated columns cannot query themselves.

To define a value bar column for a Matrix Widget:

1. Create a Widget.
2. In the Type drop-down, select Matrix.
3. Click the Columns page.
4. Click Add>Calculated column.

   

5. Define how the value will be calculated:
   1. Click the Calculated Value page.
   2. Click the Selector button , and then select the Tokens (System Functions, Expressions, Stored Values, Metrics, and/or Counters) and math operators to build the calculation.
6. Define how the value bar looks:
   1. Click the Value-Line page.

      

   2. Define the width of the value bar, either:
      • Set Complete Line Based on Largest Value: Select this radio button to auto-determine the maximum width; the width of the value bars is based on the largest value of any row. For example, if the Hardware category has a value of 10, which is the largest, then the value bar for Hardware category will fill the entire width, and all other bars will be a percentage of that width.
      • Set Specific Threshold: Select this radio button to specify a maximum width. You can then select the following options:
        • Show Values That Exceed the Threshold: Select this check box to show overages on the value bar (values that are greater than the specified threshold). Overages can be displayed in a different color (see Overage Color below). If not selected, value bars that exceed the maximum width appear cut off.
        • Draw a Line to Indicate the Threshold Position: Select this check box to draw a short vertical line to indicate the specific threshold to make it easier to see.
   3. Draw a Border Around the Value Bar: Select this check box to draw a box around the whole value bar. If not selected, the value bar is free-floating.
   4. Define the colors of the value bar:
      1. Bar Color: Select the primary color for the value bar.
      2. Bar Color Expression: Select this check box to use an Expression to conditionally change the color of the value bar. Then, define the Expression.
      3. Overage Color: Select this check box to use a specific color for overages (bars that exceed the maximum width). Then, select a color.
      4. Overage Expression: Select this check box to use an Expression to conditionally change the color of the overage. Then, define the Expression.
      5. Use Solid Colors: Select this option to use a solid color on the value bar. By default, values bars are drawn using gradients, darkening towards the bar color as they get longer.
   5. Fixed Height: Select this check box to use a fixed height for the value bar. Then, specify the height. By default, the value bar takes up a calculated percentage of the available space for the row.

7. Select OK.
