Define chart properties — including type, labels, colors, and styling.
Export the final output with the chart to a PDF format.

Example document Copy

# Use this tag in your template to generate a chart dynamically
# Orders Prices by months<<y [Sum(c => c.Price)]>><<size [Count()]>>

import groupdocs.assembly as ga

    def run():

        # Set the path to your template file
        template = "chart_template.pdf"

        # Connect to your desired data source
        data = ga.DataSourceInfo(GetChartData(), "orders")

        # Save the final document with the chart embedded
        asm = ga.DocumentAssembler()
        asm.assemble_document(template, "result.pdf", data)
