Bug ID: 60847
Summary: CTPlotArea OOXML type needs a cleaner interface
Product: POI
Version: 3.16-dev
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: P2
Component: XSSF
Assignee: dev@poi.apache.org
Reporter: gwool...@apache.org
Target Milestone: ---
It has separate methods to get lists of all the different chart types it could
possibly contain. These have many overlapping/common properties. It is really
annoying to have to write code that explicitly names each list and calls the
proper getXYZChartList() method, then call the same getTitle() method on each
one, typed explicitly.
There should be a common interface defining the common properties, perhaps even
a hierarchy of interfaces, and chart/plot wrapper/handler class, at least for
XSSF, if not common with HSSF, that can return a List of all the charts as
implementations of the common interface(s) defining all the common
methods/properties.
Callers could still get at the underlying explicit types, but in many instances
wouldn't care, and this would remove the need for a lot of boilerplate in
consumer code.
(I'm looking in particular at Vaadin Spreadsheet Charts, and the gyrations they
had to go through to get chart definitions out of POI).
