Yeah, I was wondering what that was meant to show... I only got mine the other day. As a guess, it looks like it's trying to show where you were within target, above target and below target but it's really just a guess.
Looking at the user manual (which is available online from here: https://www1.accu-chek.co.uk/documents/smartpix/SmartPix_User_EN_090518_rgb.pdf) it says the following:
"Metabolic Control
For each day of the period analysed the mean blood glucose
level (MBG) and the standard deviation
(SD/variance of the levels) are calculated. These two results
together provide the coordinates at which one entry (per
day) is made on the chart. The mean blood glucose level is
plotted along the y-axis while the standard deviation is
plotted along the x-axis.
This type of presentation produces a “point cloud”. To allow
faster assessment of the metabolic situation based on this
general picture, the chart is split up into four “quadrants”.
Each of these quadrants represents a certain constitution of
the metabolic situation and is described by the attributes
“stable/unstable” (depending on the standard deviation) and
“low/high” (depending on the mean blood glucose levels).
Each quadrant thus has two attributes.
Example:
Mean blood glucose levels below 150 mg/dL (or 8.3 mmol/L)
with a standard deviation of less than 50 mg/dL (or
2.8 mmol/L) are plotted in the left lower quadrant. The latter
has the attributes “stable-low”. If both levels are above those
limits, the entry is made in the right upper quadrant
(“unstable-high”).
Two ellipses are plotted, centred around the mean level of all
represented levels (marked by a blue cross). They illustrate
the variance of the daily mean levels and the daily blood
glucose variations over the selected period as a simple (1
SD) and two-fold (2 SD) standard deviation of the levels
displayed.
Good metabolic control can be recognised by as many dots
as possible in the “stable-low” quadrant (bottom left); there
should, however, have been no cases of hypoglycemia, or as
few as possible in the relevant period."
