About the library Bodoconsult.Core.Charting

What does the library

Bodoconsult.Core.Charting is a library for creating charts from database data. The workflow for using the library is generally as follows:

  1. Getting data as DataTable from a database
  2. Create a ChartData object to make general settings for the chart and load the data from the DataTable as List
  3. Create a ChartHandler and deliver the ChartData object to it
  4. Export the data to a file

To work properly the DataTable objects must have a certain logical structure depending on the type of chart you want to create.

How to use the library

The source code contains NUnit test classes the following source code is extracted from. The samples below show the most helpful use cases for the library.

Chart data input

All chart types require a IList as input.

There are three classes implementing IChartItemData: ChartItemData, PieChartItemData and PointChartItemData. See the description for each chart type below for the required type of data input.

Style the charts

Chart styling is based on the class ChartStyle from the library Bodoconsult.Core.Typography you can download via Nuget. See the following code fragments for how chart styling is done in the test project.


    public static class TestHelper
    {
		...
		
        /// <summary>
        /// Load a default style for the charts
        /// </summary>
        /// <param name="chartData"></param>
        /// <param name="highResolution"></param>
        public static void LoadDefaultChartStyle(ChartData chartData, bool highResolution = false)
        {

            var chartStyle = GlobalValues.DefaultTypography().ChartStyle;

            if (highResolution)
            {
                chartStyle.Width = 4500;
                chartStyle.Height = 2781;
                chartStyle.FontSize = 12;
            }

            chartStyle.CopyrightFontSizeDelta = 0.6F;
            chartStyle.BackgroundColor = Color.Transparent;
            //_chartStyle.AxisLineColor = Color.DarkBlue;

            //
            chartData.ChartStyle  = chartStyle;
            chartData.Copyright = "(c) Testfirma";

        }
		
		
	...
    }



    public static class GlobalValues
    {
        /// <summary>
        /// Get a elegant default typography
        /// </summary>
        /// <returns></returns>
        public static ITypography DefaultTypography()
        {
            var typography = new ElegantTypographyPageHeader("Calibri", "Calibri", "Calibri")
            {
                ChartStyle =
                {
                    Width = 750,
                    Height = 464,
                    FontSize = 10,
                    BackGradientStyle = GradientStyle.TopBottom,
                }
            };

            return typography;
