Add option for user-defined fit line model in visualizations

Currently, we are able to draw fit lines in bubble charts via the Insights menu by enabling the Show fit line option. However, this option chooses the model of the fit line automatically to always be the "best fit" for the data as deemed by Cognos, be it a linear or a quadratic relationship. In some cases the business logic of the x and y variables may necessitate examining e.g. the goodness of linear fit in particular, but the automation may spuriously plot a quadratic line depending on the observations plotted.


A new option Fit line model shall be added to the visualization insights menu. The option should allow the user to select between Automatic as selected by the automatic algorithm and user-forced Linear or Quadratic models. Furthermore, a No constant term option should exist, allowing users to force at least the linear fit line to cross the axis' origin.

    Hi, You can do this today in Reporting by defining a calculation for the Baselines - can you confirm if you would like this feature in report visualizations or in dashboarding.
