The trend charts contain both score and cost graphs that plot the score or cost values in the vertical axis against all the scorecard runs in the horizontal axis. By default, the trend chart shows data from the last 10 scorecard runs. You can view the number of total rows and invalid rows for the metric in the trend chart. The trend chart also displays whether the score and cost trends remained constant or moved up or down based on the last scorecard run.

The Analyst tool uses the historical scorecard run data for each date and latest valid score values to calculate the score. The Analyst tool uses the latest threshold settings in the chart to depict the color of the score points. You can view the Good, Acceptable, and Unacceptable thresholds for the score. The thresholds change each time you run the scorecard after editing the values for scores in the scorecard. When you export a scorecard, the Analyst tool includes the trend chart information including the score and cost information in the exported file.
