Subject: tdf#138556 Don’t add Open Values to stock chart types 1 and 3
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A new function was defined, XdataInterpreter::getChartTypeSpecificData.
Being 100% chart-type-agnostic when retrieving chart data is impossible;
candlestick charts can have different numbers of sequences per series,
and this information is not present in any other chart type.
