ASP.NET Bar Chart with Custom Labels

In this blog post we will look on how to build a bar chart with multiple series, custom X-labels and inner labels using MindFusion.Charting for ASP.NET control.

1. General Appearance of the Chart

We want to show three data series and we want to show the first values of each series in a cluster, then second cluster with the second values of each series etc. In order to render the bars in this order we set the BarType property to BarType.Clustered3D. We correct the Depth3D to make the bars less thick and increase the distance between each series with DistBtwBars. We make the bars wider, setting BarWidth to 30.

    //general appearance
    BarChart1.BarType = MindFusion.Charting.BarType.Clustered3D;
    BarChart1.BarWidth = 30f;        
    BarChart1.Depth3D = 15f;
    BarChart1.DistBtwBars = 10f;

2. Grid

Our bars are vertical e.g. it is a column chart, so we would like to have a horizontal grid. We set the GridType property to GridType.HorScale and we set the AltGridBrush and GridBruh to different gray colors to give us nice alternating grid stripes. For the outlining of the whole plot area we use the PlotAreaOutlinePen.

    //grid settings
    BarChart1.GridBrush= new MindFusion.Drawing.SolidBrush(System.Drawing.Color.FromArgb(242, 239, 224));
    BarChart1.GridPen= new MindFusion.Drawing.Pen(System.Drawing.Color.FromArgb(204, 196, 185));
    BarChart1.GridType = MindFusion.Charting.GridType.HorScale;
    BarChart1.PlotAreaOutlinePen = new MindFusion.Drawing.Pen(System.Drawing.Color.FromArgb(204, 196, 185));

3. Labels Inside Bars

The labels inside bars show the data of each bar – this is done by setting the InnerLabelType property to LabelType.Data. We use a white LabelBrush to draw the labels and set their InnerLabelBorder to Border.RoundedRect. The background of the inner labels is set to gray.

    //inner labels settings
    BarChart1.InnerLabelBackground = new MindFusion.Drawing.SolidBrush(System.Drawing.Color.FromArgb(112, 128, 144));
    BarChart1.InnerLabelBorder = MindFusion.Charting.Border.RoundedRect;
    BarChart1.InnerLabelType = MindFusion.Charting.LabelType.Data; 
    BarChart1.LabelBrush = new MindFusion.Drawing.SolidBrush(System.Drawing.Color.FromArgb(255, 255, 255));

4. Title

We want not only title but also second title – or a subtitle. That’s why we use both the TitleText and SubTitleText properties. We leave no distance between them – we set SubTitleOffset to 0. But we would like the two titles to be well above the plot area, that’s why we set bigger TitleOffset.

    //title and subtitle
    BarChart1.SubTitleOffset = 30;
    BarChart1.SubTitleText = "all major continents";
    BarChart1.TitleOffset = 0;
    BarChart1.TitleText = "Sales";

5. Labels at the Axes

The X-labels are custom text – we set them with XLabels. The title of the Y-axis is rotated, so we use LabelOrientation.BottomToTop.

    //axes labels settings
    BarChart1.XAxisSettings.LabelSeriesIndex = 1;
    BarChart1.XLabels.Add(new List(){ "Europe", "Asia", "North America", "South America"});
    BarChart1.YAxisSettings.TitleLabel = "in mlns. USD";
    BarChart1.YAxisSettings.TitleLabelOrientation = MindFusion.Charting.LabelOrientation.BottomToTop;
