Subtitles?

[Steve]

I looked around through the forums and documentation but could not find anything... is there a way to set a subtitle of the chart, that is one a different line with the main title, that uses a different font and/or color?

Hello Steve,

Thank you for writing.

You can use the HTML-like Text Formatting to set the chart title. 

Let me know if you have additional questions.

Hi Steve,

Here is the correct link: HTML-like Text Formatting.

Please let me know if there is something else I can help you with.

Unfortunately I encountered a problem with this solution. It looks fine on the screen but when I call ExportToImage, it renders the HTML code to the image. The attached file cdf-screenshot is how it looks on the screen and the file cdf-exporttoimage is how it looks after calling ExportToImage

Hello Steve,

Thank you for writing back.

This is considered an issue and I have logged it in our Feedback Portal. It is caused because the text is not painted with the correct method. You can track the item for status changes and add your vote for it here.

To workaround this you can manually paint the text:

private void radButton1_Click(object sender, EventArgs e)
{
    radChartView1.ShowTitle = false;

    TextPrimitiveHtmlImpl impl = new TextPrimitiveHtmlImpl();
    TextParams textParams = this.radChartView1.ChartElement.TitleElement.TextParams;
    SizeF size = impl.MeasureOverride(new SizeF(500f, 200), textParams);

    using (MemoryStream stream = new MemoryStream())
    {
        radChartView1.ExportToImage(stream, new Size(500, 500 - (int)size.Height));

        Bitmap bmp = new Bitmap(500, 500);

        using (Graphics g = Graphics.FromImage(bmp))
        {
            g.Clear(Color.White);
            textParams.paintingRectangle = new RectangleF(Point.Empty, size);
            impl.PaintPrimitive(new RadGdiGraphics(g), textParams);
            g.DrawImage(Image.FromStream(stream), 0, size.Height, 500, 500 - size.Height);
        }

        bmp.Save(@"D:\xfile.bmp");
    }

    radChartView1.ShowTitle = true;
}
