When a day is missed the graph will show a dramatic drop to >100
This gives a whole lot of false-positives when analysing the results - it looks like the keyword dropped out of the top 100.
I'd suggest changing the presentation so that either the line can start and stop when dates are missing, or ignoring the missing day and drawing a straight line between the actual results.
