ChartSeries.CategoriesFormatsArray Property
Format on the cell where the data is. So for example if you are charting a range A1:A3, this property will return an array with the numeric format strings for A1, A2 and A3.
This format is applied to the data if the data format for the axis or the label is null.
Each value in the array holds the format for one data point in the chart.
Remarks
You can't change this value, since it is the cell format. To change it, change the cell formats for the data instead. If the category axis has more than one level of labels, this property will return each level as a row in an array. To get all levels concatenated by carriage returns, use CategoriesFormats
