Create a Clustered Column Chart in Excel in Python

To add a chart to a worksheet, use Worksheet.Chart.Add(ExcelChartType chartType) method. The ExcelChartType enumeration includes various chart types predefined in MS Excel. The following are the steps to add a clustered column chart in Excel using Spire.XLS for Python.

• Create a Workbook object.
• Get a specific worksheet through Workbook.Worksheets[index] property.
• Write data into the specified cells.
• Add a clustered column char to the worksheet using Worksheet.Chart.Add(ExcelChartType.ColumnClustered) method.
• Set the chart data through Chart.DataRange property.
• Set the position, title, and other attributes of the chart through the properties under the Chart object.
• Save the workbook to an Excel file using Workbook.SaveToFile() method.

from spire.xls import *
from spire.xls.common import *

# Create a Workbook object
workbook = Workbook()

# Get the first sheet
sheet = workbook.Worksheets[0]

# Set chart data
sheet.Range["A1"].Value = "Product"
sheet.Range["A2"].Value = "Diet Coke"
sheet.Range["A3"].Value = "Mountain Dew"
sheet.Range["A4"].Value = "Diet Pesi"
sheet.Range["A5"].Value = "Cherry Coke"

sheet.Range["B1"].Value = "Store A"
sheet.Range["B2"].NumberValue = 35000
sheet.Range["B3"].NumberValue = 46000
sheet.Range["B4"].NumberValue = 28000
sheet.Range["B5"].NumberValue = 51000
sheet.Range["C1"].Value = "Store B"
sheet.Range["C2"].NumberValue = 41000
sheet.Range["C3"].NumberValue = 32000
sheet.Range["C4"].NumberValue = 38000
sheet.Range["C5"].NumberValue = 40000

# Set cell style
sheet.Range["A1:C1"].RowHeight = 15
sheet.Range["A1:C1"].Style.Color = Color.get_Black()
sheet.Range["A1:C1"].Style.Font.Color = Color.get_White()
sheet.Range["A1:C1"].Style.VerticalAlignment = VerticalAlignType.Center
sheet.Range["A1:C1"].Style.HorizontalAlignment = HorizontalAlignType.Center
sheet.AutoFitColumn(1)

# Add a chart to the sheet
chart = sheet.Charts.Add(ExcelChartType.ColumnClustered)

# Set data range of chart
chart.DataRange = sheet.Range["A1:C5"]
chart.SeriesDataFromRange = False

# Set position of the chart
chart.LeftColumn = 5
chart.TopRow = 1
chart.RightColumn = 14
chart.BottomRow = 21

# Set chart title
chart.ChartTitle = "Store Wise Soda Soft Drink Sales"
chart.ChartTitleArea.IsBold = True
chart.ChartTitleArea.Size = 12

# Set axis title
chart.PrimaryCategoryAxis.Title = "Product"
chart.PrimaryCategoryAxis.Font.IsBold = True
chart.PrimaryCategoryAxis.TitleArea.IsBold = True
chart.PrimaryValueAxis.Title = "Sales"
chart.PrimaryValueAxis.HasMajorGridLines = False
chart.PrimaryValueAxis.TitleArea.IsBold = True
chart.PrimaryValueAxis.TitleArea.TextRotationAngle = 90

# Set series color, overlap, gap width and data labels
series = chart.Series
for i in range(len(series)):
    cs = series[i]
    cs.Format.Options.IsVaryColor = True
    cs.Format.Options.Overlap = -50
    cs.Format.Options.GapWidth = 350
    cs.DataPoints.DefaultDataPoint.DataLabels.HasValue = True

# Set legend position
chart.Legend.Position = LegendPositionType.Top

# Save the document
workbook.SaveToFile("ClusteredColumnChart.xlsx", ExcelVersion.Version2016)
