Bugs: curves

Table of Contents



NaNs and +/-inf are currently filtered out of curve and histogram data.

This filtering is not performed for other data (e.g. contours, lines)

Line segments

The joints between line segments for curves can be very visible if the lines are thick; for instance

chips> clear()
chips> add_curve([1,1.4,2], [1,2,2])
chips> set_curve(['', 'none', 'line.thickness', 10])


[The join between the two lines at (1.4,2) is not smooth]
