trueCall and Daisy
I couldn’t resist taking my call records from trueCall and putting them in Daisy.
After a minute or so, I was able to draw a simple Daisy chart.
A Daisy Chart of trueCall Data
Obviously, this doesn’t show that much, as only a few records were used to draw the chart.
On the other hand, charts such as this could be used to show perhaps that a particular nuisance call tends to happen between 21:00 and 23:00 on a Wednesday night. Years ago, a chart such as this, drawn of all phone box fraud in Wales, led to the arrest and conviction of one of the Principality’s biggest drug dealers.
