Returns the formula for the categories the values are plotted against — the x values of a
scatter or bubble series — or null if the series states none.
Returns the cells getCategoriesFormula names, or null.
getValuesRange for when there are none to return.
Returns how the series is drawn. The same as IChart.getChartType except in a combo.
Returns the formula naming the series — Sales!$C$3 — or null when the name is written
into the chart, or there is none.
Returns the cells getNameFormula names, or null.
getValuesRange for when there are none to return.
Returns the cells getValuesFormula names.
null when the formula is not one plain reference into this workbook: an array
literal, a defined name, several areas, another workbook, or #REF!.
Returns true if the series is plotted against the secondary axes.
One series of a chart: what it is called and the cells it plots.
Remarks
Each part of a series is stated as a formula —
Sales!$C$4:$C$15— the way the file and a chart's own dialog state it. The formula is the contract: it is what can say#REF!, name a defined name, or point at another workbook. Theget…Rangeforms resolve the plain case.
