Practising the following steps, you can insert a Column Chart in MS Excel 2013:

As a report developer, you are required to share contract price by manager dynamically with the following key requirements:

• The report must show the name of the manager
• The report must show the total contract price for each manager
• Series color to be used in chart series
• The report must be generated in the Spreadsheet Document

<Total Contract Prices by Managers<<foreach [m in
managers]>><<x [m.Manager]>>

="Total Contract Price<<y [m.Total_Contract_Price]>><<seriesColor [color]>>"

Please download the sample Dynamic Chart Series Color document we created in this article:

• dynamic-chart-series-color.xlsx

For a chart with dynamic data, you can set colors of chart series dynamically based upon expressions. To use the feature, do the following steps:

• Declare a chart with dynamic data in the usual way

• For chart series to be colored dynamically, define corresponding color expressions in names of these series using seriesColor tags having the following syntax:

  <<seriesColor [color_expression]>>
  

A color expression must return a value of one of the following types:

• A string containing the name of a known color, that is, the case-insensitive name of a member of the KnownColor enumeration such as “red”
• An integer value defining RGB (red, green, blue) components of the color such as 0xFFFF00 (yellow)
• A value of the Color type

Following code snippet generates the report:

from groupdocs.assembly import DataSourceInfo, DocumentAssembler
from groupdocs.assembly.data import DocumentTable, DocumentTableOptions

options = DocumentTableOptions()
options.first_row_contains_column_names = True
table = DocumentTable("managers.docx", 1, options)
table.columns["Total_Contract_Price"].type = float

assembler = DocumentAssembler()
assembler.assemble_document("dynamic-chart-series-color.xlsx", "dynamic-chart-series-color-report.xlsx", [
    DataSourceInfo(table, "managers"),
    DataSourceInfo("Coral", "color"),
])
