3.6. Generating Charts and Graphs:

IronXL allows you to create charts and graphs directly from your Python code. For example, in the Python Excel application you can create a bar chart with the following code:

from ironxl import *     workbook = WorkBook.Load("test.xlsx")
worksheet = workbook.DefaultWorkSheet // Excel sheet
chart = worksheet.CreateChart(ChartType.Line, 10, 10, 18, 20)
series = chart.AddSeries("A1:A5", "B1:B5")
series.Title = "Line Chart"
chart.Position.LeftColumnIndex = 2
chart.Position.RightColumnIndex = chart.Position.LeftColumnIndex + 3

This code adds a clustered bar chart to the worksheet, using data from cells A1 to A5 as the category labels and data from cells B1 to B5 as the series values. The chart title is set to "Line Chart".
