I am using loop to create multile line charts in ppt. For country ( Column A)=AR I am plotting line charts for different C=1,2 and 3 on same plot. In the Y axis I will have column D and on X axis I will have column B

Similary for different country.

Question 1: I am not able to choose particular line graph available in ppt which also shows Y-DATA LABELS. Also my X-axis is not properly formatted. How to align x labels 45 degree slanting.

Here is the code for one country:

chart_data = ChartData()
cat=['202001','202002','202003','202004','202005','202006','202007']
chart_data.categories = cat
        
for i in list(data["C"].unique()):
            
    chart_data.add_series(i,tuple(data[data['C']==i]['D']))
    x, y, cx, cy = Inches(1), Inches(1), Inches(10.5), Inches(6)
    chart = slide.shapes.add_chart(XL_CHART_TYPE.LINE, x, y, cx, cy, chart_data).chart

    chart.has_legend = True
    chart.legend.include_in_layout = False
    chart.series[0].smooth = True

Here is the output that I get:

Expected Output is

Question 2: How can I add a dotted vertical line, move the legend to the top and change font size of legend, and finally to add xlabel, ylabel and titles using the above code?

Please help.
