Charts With Dynamic Series (VB.Net / netframework)
Note
This demo is available in your FlexCel installation at <FlexCel Install Folder>\samples\vb\VS2022\netframework\20.Reports\75.Charts With Dynamic Series and also at https://github.com/tmssoftware/TMS-FlexCel.NET-demos/tree/master/vb/VS2022/netframework/Modules/20.Reports/75.Charts With Dynamic Series
Overview
Examples of how to create a chart with one series per row. Charts with one series per row are not a common thing to do. You will normally want your series in columns, as shown in the example Charts. Even for this demo, the charts would probably look better if we had them with one series per column. But if you need to do it, you can use this example as a base.
Concepts
How to use swap series to create a chart with a series per row, as explained in Creating charts with dynamic series.
To use <#swap series> in an embedded chart, you name the chart with a name containing <#swap series>.The tag will be removed from the final chart name. To use <#swap series> in a chart sheet, you write it on the sheet name. And again, the tag will be removed from the final sheet name.
How to use the FlexCelReport.CustomizeChart event to further customize the chart.

' General Information about an assembly is controlled through the following
' set of attributes. Change these attribute values to modify the information
' associated with an assembly.
'
<Assembly: AssemblyTitle("")>
<Assembly: AssemblyDescription("")>
<Assembly: AssemblyConfiguration("")>
<Assembly: AssemblyCompany("")>
<Assembly: AssemblyProduct("")>
<Assembly: AssemblyCopyright("(c) 2002 - 2014 TMS Software")>
<Assembly: AssemblyTrademark("")>
<Assembly: AssemblyCulture("")>
'
' Version information for an assembly consists of the following four values:
'
' Major Version
' Minor Version
' Build Number
' Revision
'
' You can specify all the values or you can default the Revision and Build Numbers
' by using the '*' as shown below:
<Assembly: AssemblyVersion("6.2.1.0")>
'
' In order to sign your assembly you must specify a key to use. Refer to the
' Microsoft .NET Framework documentation for more information on assembly signing.
'
' Use the attributes below to control which key is used for signing.
'
' Notes:
' (*) If no key is specified, the assembly is not signed.
' (*) KeyName refers to a key that has been installed in the Crypto Service
' Provider (CSP) on your machine. KeyFile refers to a file which contains
' a key.
' (*) If the KeyFile and the KeyName values are both specified, the
' following processing occurs:
' (1) If the KeyName can be found in the CSP, that key is used.
' (2) If the KeyName does not exist and the KeyFile does exist, the key
' in the KeyFile is installed into the CSP and used.
' (*) In order to create a KeyFile, you can use the sn.exe (Strong Name) utility.
' When specifying the KeyFile, the location of the KeyFile should be
' relative to the project output directory which is
' %Project Directory%\obj\<configuration>. For example, if your KeyFile is
' located in the project directory, you would specify the AssemblyKeyFile
' attribute as [assembly: AssemblyKeyFile("..\\..\\mykey.snk")]
' (*) Delay Signing is an advanced option - see the Microsoft .NET Framework
' documentation for more information on this.
