Using predefined images as fill for bar charts

[Robert]

While using the now obsolete ChartView I was able to use custom image files in .png format, (similar, but different from the currently offered GradientStyles) as a filler for my bars in BarCharts. I used:

Series[0].Items[0].Appearance.FillStyle

which had several useful Properties.

What would be the corresponding code using RadChartView to use these same images?

Thanks,
Rob

Hello Robert,

Thank you for writing.

Please have a look at the following code snippet, demonstrating how to assign an image to the elements in the BarSeries :

public Form1()
{
    InitializeComponent();

    BarSeries barSeries = new BarSeries("Performance", "RepresentativeName");
    barSeries.Name = "Q1";
    barSeries.DataPoints.Add(new CategoricalDataPoint(177, "Harley"));
    barSeries.DataPoints.Add(new CategoricalDataPoint(128, "White"));
    barSeries.DataPoints.Add(new CategoricalDataPoint(143, "Smith"));
    barSeries.DataPoints.Add(new CategoricalDataPoint(111, "Jones"));
    barSeries.DataPoints.Add(new CategoricalDataPoint(118, "Marshall"));
    this.radChartView1.Series.Add(barSeries);

    BarSeries barSeries2 = new BarSeries("Performance", "RepresentativeName");
    barSeries2.Name = "Q2";
    barSeries2.DataPoints.Add(new CategoricalDataPoint(153, "Harley"));
    barSeries2.DataPoints.Add(new CategoricalDataPoint(141, "White"));
    barSeries2.DataPoints.Add(new CategoricalDataPoint(130, "Smith"));
    barSeries2.DataPoints.Add(new CategoricalDataPoint(88, "Jones"));
    barSeries2.DataPoints.Add(new CategoricalDataPoint(109, "Marshall"));
    this.radChartView1.Series.Add(barSeries2);
}

private void Form1_Load(object sender, EventArgs e)
{
    foreach (UIChartElement element in this.radChartView1.Series[0].Children)
    {
        RadImageShape imageShape = new RadImageShape();
        imageShape.Image = Properties.Resources._2;
        element.BackColor = Color.Transparent;
        element.BackgroundShape = imageShape;
    }
}

I hope this information helps. Should you have further questions, I would be glad to help.

Yes! thank you, that works very well. I'll check out UIChartElements and RadImageShape for more features.
