// In Excel a chart series is a collection of information that defines which data is plotted such as values, axis labels and formatting.
|
|
//
|
|
// The series options that can be set are:
|
|
//
|
|
// name
|
|
// categories
|
|
// values
|
|
//
|
|
// name: Set the name for the series. The name is displayed in the chart legend and in the formula bar. The name property is optional and if it isn't supplied it will default to Series 1..n. The name can also be a formula such as =Sheet1!$A$1
|
|
//
|
|
// categories: This sets the chart category labels. The category is more or less the same as the X axis. In most chart types the categories property is optional and the chart will just assume a sequential series from 1..n.
|
|
//
|
|
// values: This is the most important property of a series and is the only mandatory option for every chart object. This option links the chart with the worksheet data that it displays.
|
|
//
|
|
// Set properties of the chart legend. The options that can be set are:
|
|
//
|
|
// position
|
|
// show_legend_key
|
|
//
|
|
// position: Set the position of the chart legend. The default legend position is right. The available positions are:
|
|
//
|
|
// top
|
|
// bottom
|
|
// left
|
|
// right
|
|
// top_right
|
|
//
|
|
// show_legend_key: Set the legend keys shall be shown in data labels. The default value is false.
|
|
//
|
|
// Set properties of the chart title. The properties that can be set are:
|
|
//
|
|
// title
|
|
//
|
|
// name: Set the name (title) for the chart. The name is displayed above the chart. The name can also be a formula such as =Sheet1!$A$1 or a list with a sheetname. The name property is optional. The default is to have no chart title.
|
|
//
|
|
// Specifies how blank cells are plotted on the chart by show_blanks_as. The default value is gap. The options that can be set are:
|
|
//
|
|
// gap
|
|
// span
|
|
// zero
|
|
//
|
|
// gap: Specifies that blank values shall be left as a gap.
|
|
//
|
|
// sapn: Specifies that blank values shall be spanned with a line.
|
|
//
|
|
// zero: Specifies that blank values shall be treated as zero.
|
|
//
|
|
// Set chart offset, scale, aspect ratio setting and print settings by format, same as function AddPicture.
|
|
//
|
|
// Set the position of the chart plot area by plotarea. The properties that can be set are:
|
|
//
|
|
// show_bubble_size

// show_leader_lines
|
|
// show_percent

|
|
// show_cat_name: Specifies that the category name shall be shown in the data label. The show_cat_name property is optional. The default value is true.
|
|
//
|
|
// show_leader_lines: Specifies leader lines shall be shown for data labels. The show_leader_lines property is optional. The default value is false.
|
|
//
|
|
// show_percent: Specifies that the percentage shall be shown in a data label. The show_percent property is optional. The default value is false.
