Hi all, Hopefully somebody has come across this before.

I am trying to create a line chart that can have repeated data in each column e.g {table} id | number 22 | 23 | 22 | 23 | 25 | 24 | {table}

My problem is the graph will only get rendered if one column has unique data.

Charting exception: Error number 0 in 5: X-value already exists. Wrapped Exception: X-value already exists. com.xpn.xwiki.XWikiException: Error number 0 in 5: X-value already exists. Wrapped Exception: X-value already exists. at com.xpn.xwiki.plugin.charts.ChartingMacro.exception(ChartingMacro.java:143) at com.xpn.xwiki.plugin.charts.ChartingMacro.execute(ChartingMacro.java:80) at com.xpn.xwiki.render.filter.MacroFilter.handleMatch(MacroFilter.java:90) at org.radeox.filter.regex.RegexTokenFilter$1.handleMatch(RegexTokenFilter.java:91) at org.radeox.regex.JdkMatcher.substitute(JdkMatcher.java:48) at org.radeox.filter.regex.RegexTokenFilter.filter(RegexTokenFilter.java:89) at org.radeox.filter.FilterPipe.filter(FilterPipe.java:169) at com.xpn.xwiki.render.XWikiRadeoxRenderEngine.render(XWikiRadeoxRenderEngine.java:92) at com.xpn.xwiki.render.XWikiRadeoxRenderer.render(XWikiRadeoxRenderer.java:118)

If i make all the data unique in one column above then the chart renders ok. Is there a parameter that i can use to allow repeated data or is the charting macro designed to have one column with unique data?

Regards, John Carroll

I need to draw a line chart for my manager *today*, and I cannot figure out how to use the chart macro parameters correctly.

Could someone please post the chart macro syntax that was used to generate the line charts displayed on the XWiki.org chart macro sample page? http://code.xwiki.org/xwiki/bin/view/Macros/ChartingSamples

Thank you very much!!
