Charts¶
python-pptx provides an API for adding and manipulating charts. A chart object, like
a table, is not a shape. Rather it is a graphical object contained in
a GraphicFrame
shape. The shape API, such as position, size, shape id, and
name, are provided by the graphic frame shape. The chart itself is accessed
using the chart
property on the graphic frame shape.
Chart
objects¶
The Chart
object is the root of a generally hierarchical graph of component
objects that together provide access to the properties and methods required
to specify and format a chart.
- class pptx.chart.chart.Chart(chartSpace, chart_part)[源代码]¶
A chart object.
- property category_axis¶
The category axis of this chart. In the case of an XY or Bubble chart, this is the X axis. Raises
ValueError
if no category axis is defined (as is the case for a pie chart, for example).
- property chart_style¶
Read/write integer index of chart style used to format this chart. Range is from 1 to 48. Value is
None
if no explicit style has been assigned, in which case the default chart style is used. AssigningNone
causes any explicit setting to be removed. The integer index corresponds to the style’s position in the chart style gallery in the PowerPoint UI.
- property chart_title¶
A
ChartTitle
object providing access to title properties.Calling this property is destructive in the sense it adds a chart title element (c:title) to the chart XML if one is not already present. Use
has_title
to test for presence of a chart title non-destructively.
- property chart_type¶
Member of XL_CHART_TYPE enumeration specifying type of this chart.
If the chart has two plots, for example, a line plot overlayed on a bar plot, the type reported is for the first (back-most) plot. Read-only.
- property has_legend¶
Read/write boolean,
True
if the chart has a legend. AssigningTrue
causes a legend to be added to the chart if it doesn’t already have one. Assigning False removes any existing legend definition along with any existing legend settings.
- property has_title¶
Read/write boolean, specifying whether this chart has a title.
Assigning
True
causes a title to be added if not already present. AssigningFalse
removes any existing title along with its text and settings.
- plots[源代码]¶
The sequence of plots in this chart. A plot, called a chart group in the Microsoft API, is a distinct sequence of one or more series depicted in a particular charting type. For example, a chart having a series plotted as a line overlaid on three series plotted as columns would have two plots; the first corresponding to the three column series and the second to the line series. Plots are sequenced in the order drawn, i.e. back-most to front-most. Supports len(), membership (e.g.
p in plots
), iteration, slicing, and indexed access (e.g.plot = plots[i]
).
- replace_data(chart_data)[源代码]¶
Use the categories and series values in the
ChartData
object chart_data to replace those in the XML and Excel worksheet for this chart.
- class pptx.chart.chart.ChartTitle[源代码]¶
Provides properties for manipulating a chart title.
- format[源代码]¶
ChartFormat
object providing access to line and fill formatting.Return the
ChartFormat
object providing shape formatting properties for this chart title, such as its line color and fill.
- property has_text_frame¶
Read/write Boolean specifying whether this title has a text frame.
Return
True
if this chart title has a text frame, andFalse
otherwise. AssigningTrue
causes a text frame to be added if not already present. AssigningFalse
causes any existing text frame to be removed along with its text and formatting.
- property text_frame¶
TextFrame
instance for this chart title.Return a
TextFrame
instance allowing read/write access to the text of this chart title and its text formatting properties. Accessing this property is destructive in the sense it adds a text frame if one is not present. Usehas_text_frame
to test for the presence of a text frame non-destructively.
Legend
objects¶
A legend provides a visual key relating each series of data points to their assigned meaning by mapping a color, line type, or point shape to each series name. A legend is optional, but there can be at most one. Most aspects of a legend are determined automatically, but aspects of its position may be specified via the API.
- class pptx.chart.chart.Legend[源代码]¶
Represents the legend in a chart. A chart can have at most one legend.
- font[源代码]¶
The
Font
object that provides access to the text properties for this legend, such as bold, italic, etc.
- property horz_offset¶
Adjustment of the x position of the legend from its default. Expressed as a float between -1.0 and 1.0 representing a fraction of the chart width. Negative values move the legend left, positive values move it to the right.
None
if no setting is specified.
- property include_in_layout¶
True
if legend should be located inside plot area.Read/write boolean specifying whether legend should be placed inside the plot area. In many cases this will cause it to be superimposed on the chart itself. Assigning
None
to this property causes any c:overlay element to be removed, which is interpreted the same asTrue
. This use case should rarely be required and assigning a boolean value is recommended.
- property position¶
Read/write XL_LEGEND_POSITION enumeration value specifying the general region of the chart in which to place the legend.
Axis
objects¶
A chart typically has two axes, a category axis and a value axis. In general, one of these is horizontal and the other is vertical, where which is which depends on the chart type. For example, the category axis is horizontal on a column chart, but vertical on a bar chart.
A chart where the independent variable is in a continuous (numeric) range, such as an XY/scatter chart, does not have a category axis. Rather it has two value axes.
A category is perhaps most commonly a string label, such as 'East'
or
'Revenue'
; however a category can also be a number or a date (although
all categories in a chart must be the same type).
When a chart’s categories are dates, the category axis is generally, but not
necessarily a DateAxis
object.
A Chart may have zero to four axes. A pie chart, for example, has neither a category nor a value axis.
- class pptx.chart.axis._BaseAxis[源代码]¶
Base class for chart axis objects. All axis objects share these properties.
- property axis_title¶
An
AxisTitle
object providing access to title properties.Calling this property is destructive in the sense that it adds an axis title element (c:title) to the axis XML if one is not already present. Use
has_title
to test for presence of axis title non-destructively.

The
ChartFormat
object providing access to the shape formatting properties of this axis, such as its line color and fill.
- property has_major_gridlines¶

True
to this property causes major gridlines to be displayed. AssigningFalse
causes them to be removed.
- property has_minor_gridlines¶
Read/write boolean value specifying whether this axis has gridlines at its minor tick mark locations. Assigning
True
to this property causes minor gridlines to be displayed. AssigningFalse
causes them to be removed.
- property has_title¶
Read/write boolean specifying whether this axis has a title.
True
if this axis has a title,False
otherwise. AssigningTrue
causes an axis title to be added if not already present. AssigningFalse
causes any existing title to be deleted.
- major_gridlines[源代码]¶
The
MajorGridlines
object representing the major gridlines for this axis.
- property major_tick_mark¶
Read/write XL_TICK_MARK value specifying the type of major tick mark to display on this axis.
- property maximum_scale¶
Read/write float value specifying the upper limit of the value range for this axis, the number at the top or right of the vertical or horizontal value scale, respectively. The value

indicates the upper limit should be determined automatically based on the range of data point values associated with the axis.
- property minimum_scale¶
Read/write float value specifying lower limit of value range, the number at the bottom or left of the value scale.
None
if no minimum scale has been set. The valueNone
indicates the lower limit should be determined automatically based on the range of data point values associated with the axis.
- property minor_tick_mark¶
Read/write XL_TICK_MARK value specifying the type of minor tick mark for this axis.
- property reverse_order¶
Read/write bool value specifying whether to reverse plotting order for axis.
For a category axis, this reverses the order in which the categories are displayed. This may be desired, for example, on a (horizontal) bar-chart where by default the first category appears at the bottom. Since we read from top-to-bottom, many viewers may find it most natural for the first category to appear on top.
For a value axis, it reverses the direction of increasing value from bottom-to-top to top-to-bottom.
- tick_labels[源代码]¶
The
TickLabels
instance providing access to axis tick label formatting properties. Tick labels are the numbers appearing on a value axis or the category names appearing on a category axis.

Return
True
if this axis title has a text frame, andFalse
otherwise. AssigningTrue
causes a text frame to be added if not already present. AssigningFalse
causes any existing text frame to be removed along with any text contained in the text frame.
Value Axes¶
Some axis properties are only relevant to value axes, in particular, those related to numeric values rather than text category labels.
- class pptx.chart.axis.ValueAxis[源代码]¶
An axis having continuous (as opposed to discrete) values.
The vertical axis is generally a value axis, however both axes of an XY-type chart are value axes.
- property crosses¶

Read/write string (e.g. “$#,##0.00”) specifying the format for the numbers on this axis. The syntax for these strings is the same as it appears in the PowerPoint or Excel UI. Returns ‘General’ if no number format has been set. Note that this format string has no effect on rendered tick labels when
number_format_is_linked()
isTrue
. Assigning a format string to this property automatically setsnumber_format_is_linked()
toFalse
.
- property number_format_is_linked¶
Read/write boolean specifying whether number formatting should be taken from the source spreadsheet rather than the value of
number_format()
.
- property offset¶
Read/write int value in range 0-1000 specifying the spacing between the tick mark labels and the axis as a percentange of the default value. 100 if no label offset setting is present.
_BasePlot
objects¶
A plot is a group of series all depicted using the same charting type, e.g. bar, column, line, etc. Most charts have only a single plot; however, a chart may have multiple, as in where a line plot appears overlaid on a bar plot in the same chart. In the Microsoft API, this concept has the name chart group. The term plot was chosen for python-pptx to avoid the common mistake of understanding a chart group to be a group of chart objects.
Certain properties must be set at the plot level. Some of those properties
are not present on plots of all chart types. For example, gap_width
is only present on a bar or column plot.
- class pptx.chart.plot._BasePlot[源代码]¶
A distinct plot that appears in the plot area of a chart. A chart may have more than one plot, in which case they appear as superimposed layers, such as a line plot appearing on top of a bar chart.
- categories[源代码]¶
Returns a
Categories
sequence object containing aCategory
object for each of the category labels associated with this plot. TheCategory
class derives fromstr
, so the returned value can be treated as a simple sequence of strings for the common case where all you need is the labels in the order they appear on the chart.Categories
provides additional properties for dealing with hierarchical categories when required.
- property data_labels¶
DataLabels
instance providing properties and methods on the collection of data labels associated with this plot.
- property has_data_labels¶

The following properties are only present on bar-type plots, which includes both bar and column charts.
- class pptx.chart.plot.BarPlot[源代码]¶
A bar chart-style plot.
- property gap_width¶
Width of gap between bar(s) of each category, as an integer percentage of the bar width. The default value for a new bar chart is 150, representing 150% or 1.5 times the width of a single bar.
- property overlap¶
Read/write int value in range -100..100 specifying a percentage of the bar width by which to overlap adjacent bars in a multi-series bar chart. Default is 0. A setting of -100 creates a gap of a full bar width and a setting of 100 causes all the bars in a category to be superimposed. A stacked bar plot has overlap of 100 by default.
BubblePlot
objects¶
The following properties are only present on bubble-type plots.
Categories
objects¶
Category plots provide access to a Categories
object with their
.categories property.

- property flattened_labels¶
Return a sequence of tuples, each containing the flattened hierarchy of category labels for a leaf category. Each tuple is in parent -> child order, e.g.
('US', 'CA', 'San Francisco')
, with the leaf category appearing last. If this categories collection is non-hierarchical, each tuple will contain only a leaf category label. If the plot has no series (and therefore no categories), an empty tuple is returned.
- property levels¶
Return a sequence of
CategoryLevel
objects representing the hierarchy of this category collection. The sequence is empty when the category collection is not hierarchical, that is, contains only leaf-level categories. The levels are ordered from the leaf level to the root level; so the first level will contain the same categories as this category collection.

DataLabels
objects¶
A data label is text that labels a particular data point, usually with its value, allowing the point to be interpreted more clearly than just visually comparing its marker with its axis.
A DataLabels

Font
object providing text formatting for this data label.This font object is used to customize the appearance of automatically inserted text, such as the data point value. The font applies to the entire data label. More granular control of the appearance of custom data label text is controlled by a font object on runs in the text frame.
- property has_text_frame¶
Return
True
if this data label has a text frame (implying it has custom data label text), andFalse
otherwise. AssigningTrue
causes a text frame to be added if not already present. AssigningFalse
causes any existing text frame to be removed along with any text contained in the text frame.
- property position¶
Read/write XL_DATA_LABEL_POSITION member specifying the position of this data label with respect to its data point, or
None
if no position is specified. AssigningNone
causes PowerPoint to choose the default position, which varies by chart type.
Series
objects¶
A series is a sequence of data points that represent a coherent set of observations across each of the categories in the chart. For example, on a chart having regional categories “West”, “East”, and “Mid-west”, a series might be “Q1 Sales” and have values 42, 120, and 34. The series in this case coheres around the first quarter time period.
In general, the type (class) of a series object depends upon the chart type. The following properties are available on series objects of all types.
