Bug ID: 358451 Summary: Constants are not graphed correctly Product: kalgebra Version: unspecified Platform: Fedora RPMs OS: Linux Status: UNCONFIRMED Severity: normal Priority: NOR Component: general Assignee: aleix...@kde.org Reporter: richard-...@esplins.org Constants are helpful for creating lines in the viewport, for comparing against more complex functions, and for explaining what graphs are to beginning learners. Kalgebra handles constants in un-intuitive ways. Case: Y=5 attempt 1 Steps to reproduce: * 2D Graph * Add Function * 5 Expected behavior: * A straight line at y=5 (for any value of x, y equals 5) Observed behavior: " "Function type not recognized" Case: Y=5 attempt 2 Steps to reproduce: * 2D Graph * Add Function * y=5 Expected behavior: * A horizontal line at y=5 (for any value of x, y equals 5) Observed behavior: " Graph is y = x+5 (line with slope of 1, x intersect at -5 and y intersect at 5) Case: X = 5 Steps to reproduce: * 2D Graph * Add Function * X=5 Expected behavior: * A vertical line at x=5 (for any value of y, y equals 5) Observed behavior: " Graph is y = x-5 (line with slope of 1, x intersect at 5 and y intersect at -5) Reproducible: Always In the 3D case, it is similarly difficult to create lines or planes that exist only in one axis. The engine seems to handle these cases incorrectly. -- You are receiving this mail because: You are watching all bug changes.
