DataLabels class

Encapsulates a collection of all the DataLabel objects for the specified Series.

Inheritance: DataLabels → ChartTextFrame → ChartFrame

The DataLabels type exposes the following members:

Properties

Property	Description

auto_scale_font	True if the text in the object changes font size when the object size changes. The default value is True.
background_mode	Gets and sets the display mode of the background
background	Gets and sets the display mode of the background
is_automatic_size	Indicates whether the chart frame is automatic sized.
x	Gets or sets the x coordinate of the upper left corner in units of 1/4000 of the chart area.
y	Gets or sets the y coordinate of the upper left corner in units of 1/4000 of the chart area.
height	Gets or sets the height of frame in units of 1/4000 of the chart area.
width	Gets or sets the width of frame in units of 1/4000 of the chart area.
shadow	True if the frame has a shadow.
shape_properties	Gets the `ChartFrame.shape_properties` object.
is_default_pos_be_set	Indicates whether default position(DefaultX, DefaultY, DefaultWidth and DefaultHeight) are set.
default_x	Represents x of default position
default_y	Represents y of default position
default_width	Represents width of default position
default_height	Represents height of default position
is_auto_text	Indicates the text is auto generated.
is_deleted	Indicates whether this data labels is deleted.
text_horizontal_alignment	Gets and sets the text horizontal alignment.
text_vertical_alignment	Gets or sets the text vertical alignment of text.
rotation_angle	Represents text rotation angle.
is_automatic_rotation	Indicates whether the text of the chart is automatically rotated.
text	Gets or sets the text of data label.
linked_source	Gets and sets a reference to the worksheet.
text_direction	Represents text reading order.
reading_order	Represents text reading order.
direction_type	Gets and sets the direction of text.
is_text_wrapped	Gets or sets a value indicating whether the text is wrapped.
is_resize_shape_to_fit_text	Gets or sets whether a shape should be auto-fit to fully contain the text described within it. Auto-fitting is when text within a shape is scaled in order to contain all the text inside.
show_value	Represents a specified chart’s data label values display behavior. True displays the values. False to hide.
show_cell_range	Indicates whether showing cell range as the data labels.
show_percentage	Represents a specified chart’s data label percentage value display behavior. True displays the percentage value. False to hide.
show_bubble_size	Represents a specified chart’s data label percentage value display behavior. True displays the percentage value. False to hide.
show_category_name	Represents a specified chart’s data label category name display behavior.True to display the category name for the data labels on a chart. False to hide.
show_series_name	Indicates whether the series name displays for the data labels on a chart. True to show the series name. False to hide.
show_legend_key	Represents a specified chart’s data label legend key display behavior. True if the data label legend key is visible.
number_format	Represents the format string for the DataLabels object.
number	Gets and sets the built-in number format.
number_format_linked	True if the number format is linked to the cells (so that the number format changes in the labels when it changes in the cells).
separator_type	Gets or sets the separator type used for the data labels on a chart.
separator_value	Gets or sets the separator value used for the data labels on a chart.
position	Represents the position of the data label.
is_never_overlap	Indicates whether the datalabels display never overlap. (For Pie chart)
shape_type	Gets or sets shape type of data label.

Methods

Method	Description
set_position_auto	Set position of the frame to automatic
characters	Returns a Characters object that represents a range of characters within the text.
apply_font	Apply the font of the datalabels to all child nodes.

Example

from aspose.cells import Workbook
from aspose.cells.charts import LabelPositionType

# Set the DataLabels in the chart
wb = Workbook("chart.xlsx")
chart = wb.worksheets[0].charts[0]
for i in range(len(chart.n_series)):
    datalabels = chart.n_series[i].data_labels
    # Set the position of DataLabels
    datalabels.position = LabelPositionType.INSIDE_BASE
    # Show the category name in the DataLabels
    datalabels.show_category_name = True
    # Show the value in the DataLabels
    datalabels.show_value = True
    # Not show the percentage in the DataLabels
    datalabels.show_percentage = False
    # Not show the legend key.
    datalabels.show_legend_key = False
