Ubuntu Libreoffice chart going haywire in Windows

Good day All

I have a spreadsheet document (an .xls file) containing figures and charts. The border and fill properties of this document has preset RGB color combination (which I successfully added using Libreoffice options). However the charts (column graphs) continues to go haywire with sometimes its axis labels getting misaligned or entire chart looking shabby (size or position or both of graph, labels and headings getting changed)

What could be the possible solution?

I thought of locking up the .xls file (leaving only the user input area open) by password protecting the formatting of the documents. However the above problem persists.

Appreciate any help
