Mixing ScatterChart and AreaChart isn't currently possible, and also isn't planed, and I want to take this opportunity to explain the rationale behind it.
Area/Line/Column/Bar/SteppedArea/Candlestick charts are all "function charts". "Function" as in "mathematical function" - something that maps values from some domain to target values. The domain can be either discrete or continuous<http://code.google.com/apis/chart/interactive/docs/customizing_axes.html#Discrete_vs_Continuous>, and each domain value has exactly one target value (or null). Each function chart can have multiple series, where each series is a single mathematical function, configured by the series option, and all series in the chart share the same domain. ComboChart is a function chart where each series can be of different type, from the above types (yes, all of the above types, the docs are out-dated). ScatterChart, on the other hand, is not a function chart. Each "domain" value can have multiple "target" values, even within the same series (and therefor the terms "domain" and "target" aren't really accurate for scatter chart). That's why scatter chart and function charts don't mix, at least not easily. That said, you can try a ComboChart with 2 series, one of them configured with {type: 'area'} and the other configured with {type: 'line', lineWidth: 0, pointSize: 7}. This might be good enough for you. On Wed, Mar 28, 2012 at 8:08 PM, asgallant <[email protected]>wrote: > I'm afraid that this is not (yet?) possible.
