I have the following 2D bar chart setup: X axis - date (each bar is 1 day) Y axis - sales revenue One set of data (date, revenue) The date range spans 2-3 months. Straightforward enough... My question: is it possible to display month labels underneath groups of bars? Due to the x-axis spanning 2-3 months, there needs to be a clear visual separation for the months, whilst keeping it a continuous linear progression of dates. i.e. the x-axis may span dates 20/09 to 23/11. so we want to show "September" centred underneath bars 20/09-30/09, "October" underneath dates 01/10-31/10 and "November" underneath dates 01/11-23/11? What I've tried/found: Looking through the API/documentation I could only find grouping the months into "datasets" and setting up a "category" for each one. The only problem with that is it would group the days of each month next to eachother - whereas they need to be sequential... Does it need to be multi-series? Any thoughts? Is it possible - and if so how? Thanks.

plotSpacePercent did the trick - thanks. As for the side gaps - attached is the XML... any ideas appreciated! data.xml

Further to the original question/solution of using a multi-series column chart; this has worked great so far and thanks for your input. However there are some further cosmetic tweaks I'd like to make: a) How can we reduce the gap between data sets in the plot? I'd like them all to appear next to each other as if a single data set. I'm using date ranges like 10/11/2009 to 10/01/2010 - i.e. part way into a month. Use of a multi-series column chart requires a complete set of data for each category (month) - i.e. 31 days = 31 datasets - with 3 items each. Therefore I have had to pad out the 'unavailable' days with 0 values. This leaves a big gap at the start and end of the chart plot. How do we eliminate this gap?

Hi - that's a great help. Thanks very much!
