java - Apache POI set Excel chart title -

-

i'm creating excel workbook scratch. 1 of sheets contains chart, , want set chart title.

apache poi has setcharttitle method on hssfchart, neither xssfchart nor format-agnostic chart have methods set chart title. since need create .xlsx files problem me.

after poking around in poi code , ooxml specifications managed come code setting title on newly created chart:

    if (chart instanceof xssfchart) {         xssfchart xchart = (xssfchart) chart;         ctchart ctchart = xchart.getctchart();         cttitle title = ctchart.addnewtitle();         cttx tx = title.addnewtx();         cttextbody rich = tx.addnewrich();         rich.addnewbodypr();  // body properties must exist, can empty         cttextparagraph para = rich.addnewp();         ctregulartextrun r = para.addnewr();         r.sett("my chart title");     }

this seems work - can load resulting file in excel 2013 , chart there correct title.

is there easier way this? gotchas need out when changing chart title in workbook created in excel?
