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?
