Doughnut chart not displaying data labels

[talhasch]

"chart.plots[0].has_data_labels = True" does not activate data labels for doughnut charts.

@talhasch, thanks for reporting this! Can you please copy the text of your second post into the original post and delete the second one? You can also put your code snippet in between a pair of triple backticks. I'd suggest the title "Setting _BasePlot.has_data_labels = True doesn't work for doughnut".

Same here, with python-pptx@0.6.10. Here is a repro.

chart_data = ChartData()
chart_data.categories = ['Yes', 'No']
chart_data.add_series('Series 1', (42, 24))

for chart_type in [XL_CHART_TYPE.PIE, XL_CHART_TYPE.DOUGHNUT]:
    for has_data_labels in [True, False]:
        slide = presentation.slides.add_slide(presentation.slide_layouts[1])
        placeholder = slide.placeholders[13]
        chart = placeholder.insert_chart(chart_type, chart_data).chart

        for plot in chart.plots:
            plot.has_data_labels = has_data_labels

Hey @jmm @scanny , is there any fix of this issue yet ? I am still not able to add data labels in doughnut chart .

def apply_data_labels(chart): plot = chart.plots[0] plot.has_data_labels = True for series in plot.series: values = series.values counter = 0 for point in series.points: data_label = point.data_label data_label.has_text_frame = True data_label.text_frame.text = str(values[counter]) counter = counter + 1

This works @mohit879 , I am sorry there is problem with indentation.

Cool, thanks @sbthunder !

d_plot = chart.plots[0]
d_plot.has_data_labels = True
for series in d_plot.series:
    values = series.values
    counter = 0
    for point in series.points:
        ddl = point.data_label
        ddl.has_text_frame = True
        ddl.text_frame.text = str("{:.0%}".format(values[counter]))
        ddl.text_frame.paragraphs[0].font.name = "calibri"
        ddl.text_frame.paragraphs[0].font.size = Pt(9)
        ddl.font.color.rgb = RGBColor(255, 0, 0)
        counter = counter + 1`

@scanny - I have formatted the code. Is there any way to set the font color of the data labels of the doughnut chart? I am using the above code but it's not working.

@Himanshu-CEB Google is your friend for figuring out how to format code on GitHub. I can only speak for myself, but I won't even try to read code that's not formatted.

[himanshu-yaduvanshi]

@scanny - can you help me with this now as I have formatted the code.
