--- Comment #2 from Alain Fagot Bearez <alain.bea...@cua.li> --- In your code, you open twice the same file but you try to change the chart after its slideshow has been closed. This is the cause of the Rule M2.4 exception. Would you mind trying to adapt your code in order to avoid this? You might also be interested in trying the code available in the pull request #68 which could make it easier to define new values for your chart. https://github.com/apache/poi/pull/68 In that branch you would find a BarChartDemo under the examples, which shows how to access the charts without closing the presentation. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@poi.apache.org For additional commands, e-mail: dev-h...@poi.apache.org
