A chart type is determined by the chart:class attribute (19.15 ODF 1.3) of the <chart:chart> or <chart:series> element. The value of this attribute is a namespaced token. So it is easily possible to introduce a new chart type for "ODF extended". We could use chart:class="loext:min-max-bar", for example. Introducing a new subtype of the column or bar chart would be possible too. That has been done for the bar-of-pie and pie-of-pie chart types. It has introduced the attributes loext:sub-bar and loext:split-position at the <chart:chart> element. I don't like that solution. I would prefer to have it in the <style:style> element and have a dedicated new chart type, see bug 163921. We have already min-max bars as opening-closing bar in the stock chart type. Minimum and maximum values are given as separate <chart:series> elements and the fact that a min-max-bar has to be drawn is given by the chart:japanese-candle-stick="true" attribute in the style element of the chart in the ODF file markup. Internally the series are distinguished by the Role property, "values-min" and "values-max" for this case. For the new proposed chart type, details of an ODF markup has to be discussed. But I see no principle problems with ODF. I would not call it "stacked", because the term "stacked" includes a summing up. But in the proposed new chart type, several series use the same place on the category axis without summing up their values. Such placement is already possible by using "Overlap=100%" in a column/bar chart. So the only new aspect would be to describe a column/bar by minimum-maximum. I thing, that the requested chart type is useful. -- You are receiving this mail because: You are the assignee for the bug.
