I don't see the bug. Third and fourth chart in Sheet2 contain a data range 

Third Chart: $Sheet2.$A$2380:$B$5190
Fourth Chart: $Sheet2.$A$3592:$B$5042

But starting in row 4069 there are **no** x-values, while there are y-values up
to row 5270. No x-values are taken as "0" and hence you get date 1899-12-30
(which is based on default calc settings day 0). Adapt data ranges to be last
row 

Third Chart: $Sheet2.$A$2380:$B$4068
Fourth Chart: Fourth Chart: $Sheet2.$A$3592:$B$4068</pre>
