How to Create a Heat Map with Color Background

RIPL 7 introduced the ability to generate a scatter chart with a yellow-to-red background. This type of chart is also called a heat map, where x,y values are considered more severe as the points are plotted up and to the right. Typically, a heat map is used to plot Likelihood of Failure on one axis and Consequence of Failure on the other axis, rendering a visual that quickly identifies segments with the highest overall risk.

1. To enable a yellow-to-red color gradient for a RIPL scatter chart, have your database administrator set the MatrixColorChart parameter in the dbo Settings table of your RIPL database to either Yes or YesWithCounts.



2. In RIPL, select the components you want to be included in your chart in the component hierarchy frame. Make sure click the blue check icon .

3. Select the risk evaluation for the Risk of Failure (often called ROF in many RIPL databases) to display the analyzed data grid. Ensure that the model state is green , which means the analysis has run with the most up to date information and configurations within RIPL.

4. Within the grid, left-click the top of the COF column; then shift+left click the LOF column.

5. Click Matrix.



6. The matrix chart will display, as well as a heat map, similar to the one shown. If not, try right-clicking the chart and changing both the X-Axis and Y-Axis to four divisions. The yellow-to-red background only works on a 4x4 matrix.



7. Each point on the heat map represents a dynamic segment within the Risk of Failure evaluation. The more a datapoint is to the right and the higher up on the chart it is placed equals more risk. Click on a datapoint to display a dialog box with details for LOF, COF, ROF score as well as the component the segment is on and its linear referenced location.
