8.4 Graph and Sort Error Tools
The Graph screen shows
each color in the Teach
data drawn together on a
graph. This helps to
visualize difficult points
where taught colors
overlap due to similarity or
a large standard deviation.
The graph shows the sort
data separated out by red,
green, blue and intensity.
A Sort Output taught to a
color with a large standard
deviation will display as a
wide curve, darker colors
will display to the left of
the graph, and lighter
colors will display on the
right. The current reading
for each color is displayed
as vertical line.
In the example shown, Sort Output 4 is unique (no overlaps) in red, green and blue, and overlaps with
just one other output (one other color) in the intensity readings. This makes the color associated with
Sort Output 4 very easy to distinguish. There are no other overlaps in intensity, so the six different
colors in this example can be easily separated, and will likely separate best with relatively high
weighting factors for Blue and Intensity. (Note that the current reading (vertical lines) does not match
with any of the taught data, indicating that the sensor was not seeing any of the taught colors at the time
the screenshot was captured).
The Sort Error screen shows the current calculated error for each sort
output. This tool can help determine how well the sample the sensor is
currently reading is matched and distinguished from other colors. These
numbers can also help in manually determining the error limit value.
