Conclusion
Calc makes saving a chart as a stand-alone images easy. Excel for Windows method is longer, harder, and more cumbersome. While many Office users may not be concerned with making their charts stand-alone, others need this capability desperately. Anyone who needs to post their charts to a Website or share it independently of the application used to create it will find this feature important.
Calc’s simplicity gives it a great advantage over Excel in this regard. The open-source application has another advantage as well. It is flexible. Calc can open documents in Excel formats and typically not break the formatting of those documents.
Charts created in Excel spreadsheets still appear when the documents are opened with Calc. When a chart created in Excel is right-clicked on in Calc the “Save as Image” is in the list.
Excel users may find that using LibreOffice as a companion application for creating stand-alone graphs is much easier than using the copy and paste method that Microsoft recommends. In many ways Excel is more advanced than Calc. However, the open-source application has some features and functions that it does better than Excel or does better.
This is clearly one of them.
