Which does make me guess the generated code is "--start end-{$variableName}".
If you entered 1467142510, the resulting starttime will be too low.

Try entering the number 86400. Does this work? If so, my guess is right
and you need to enter the length (time wise) of the graph, not the start
time of it.
