            Bug ID: 112016
           Summary: Calc Diagram rendered/cached image not the same as
                    current diagram picture
           Product: LibreOffice
           Version: 5.3.4.2 release
          Hardware: All
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Calc
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: gstr1234 at gmail.com

Novadays I've noticed that a diagram's picture different in Calc screen as copy
the pasted picture in writer. (not fuzzy or empty, it seems correct diagram but
values were invalid on it.)

My ods has 20 diagrams. Data of them are calculated by many functions on many
sheets. I used to copy diagrams to writer odt document.

When I noticed this thing I have made png-s by saving as html and I found 2
pngs from 20 which weere not the same as picure shown in calc for the same type
diagram.

Those pngs were the correct diagrams of a previous version of the current ods
file. (this ods is reused annually with different data set)

It means for me that diagrams (can) have saved pictures (image cache?) inside
the ods and for some reason in my ods those old images were not replaced when
the diagram was redrawn de to source data change.

Finally I found CTRL-SHIFT-F9 which recalculates and redraw diagrams and
replaces the stored images as well .... If I don't forget  it!!!!

I guess it would be a very useful and desirable change in LO to delete cached
version of digarams as a 1st step when a diagram is redrawn on screen due to
data change. It would be much better than pasting an incorrect diagram which
sometimes almost invisible until somebody asks sg like this on a meeting: How
the hell can be this number 2 today when you've promised it will be 4.5 at
least till the end of this year!!! 

The only thing I remember when I have copied diagrams that I was faster than LO
could refresh everything. Maybe I have saved earlier the ods than previous
diagram chache refresh process finished on all diagrams (?)
After CTRL-SHIFT-F9 all diagrams were correctly copied to writer. But an error
message wuld be much better than a different picture in target document.
