Line Chart
The line chart plots the results in a line chart. The min and max ranges on the X and Y axis are from the Range Low and Range High (AMR) set within the Test Settings.
X-axis = Reference results
Y-axis = Actual results
Solid Black Line = Line of best fit
Dotted Red Line = TEa min and max
Dotted Blue Line = If using SEa or REa, the min and max acceptable for that Error Allowance
Error Index Chart
Error Index Chart is used to visualize the differences between actual and the Error Allowance from the reference value, helping to assess the accuracy of a model.
Y-axis - Error Index: Error Allowance from the reference value.
X-axis -Actual Result.
0 Line - Ideal prediction, no error.
Red Lines - Error thresholds at +1 and -1 – acceptable error range.
Data Points - Error for each observation – closer to 0 means better prediction.
Bias Chart
The bias chart visually represents the difference between measured and reference values, highlighting systematic and random error.
Y-Axis - Bias between measured and reference results.
X-Axis - Measured result value
Dotted Line - Mean bias. A large mean bias can indicate a shift or systemic error.
Percentage Bias Chart
The percentage bias chart visually represents the difference between measured and reference values.
Y-Axis - Percent bias between measured and reference results.
X-Axis - Measured result value
