Greetings!

I have to create rectangle using C#, can anyone help me with this this?

Code for currently rectangle:
Code: Select all
 public static ChartDataLabel Add(this ChartDataLabelCollection dataLabels, int paragraphs)
        {
            var cd = dataLabels.Add();

            cd.LabelValueVisible = true;
            cd.TextFrame.Paragraphs.Clear();
            for (int i = 0; i < paragraphs; i++)
            {
                cd.TextFrame.Paragraphs.Append(CreateParagraph());
            }

            return cd;
        }

        public static ChartDataLabel Add(this ChartDataLabelCollection dataLabels, string text)
        {
            var cd = dataLabels.Add(1);
            cd.TextFrame.Paragraphs[0].Text = text;

            return cd;
        }

        public static TextParagraph CreateParagraph()
        {
            var paragraph = new TextParagraph
            {
                Alignment = TextAlignmentType.Left,
                Text = string.Empty
            };
            paragraph.FirstTextRange.Format.FontHeight = 8;
            return paragraph;
        }

Dear rokaf,

Thanks for your inquiry.
According to your picture, I guess below two requirements are what you want.
1. Change the color of shape line to black, if so, please refer to following code.
Code: Select all
            var cd = dataLabels.Add();           
            cd.LabelValueVisible = true;
            //change the line color
            cd.Line.FillFormat.FillType = FillFormatType.Solid;
            cd.Line.FillFormat.SolidFillColor.Color = Color.Black;
           //your code...


2. Do you want to change the data label shape as below ?

You could provide us with the expected MS PPT file for further investigation.

Dear rokaf,

Thanks for your information again.
There is no direct way to set the transparency at present, yet there is a workaround that is using alpha when filling the color. Sample code for your reference:
Code: Select all
            cd.Fill.FillType = FillFormatType.Solid;
            cd.Fill.SolidColor.Color = Color.FromArgb(0x60,Color.Red);

I have one more question: how can I add outline shadow to my rectangle?

Here is how my code looks like:

Code: Select all
        public static ChartDataLabel Add(this ChartDataLabelCollection dataLabels, int paragraphs)
        {
            var cd = dataLabels.Add();

            cd.LabelValueVisible = true;
            cd.TextFrame.Paragraphs.Clear();

            cd.Fill.FillType = FillFormatType.Solid;
            cd.Fill.SolidColor.Color = Color.FromArgb(0x99, Color.White);
           

            cd.Line.FillFormat.FillType = FillFormatType.Solid;
            cd.Line.FillFormat.SolidFillColor.Color = Color.Black;
            for (int i = 0; i < paragraphs; i++)
            {
                cd.TextFrame.Paragraphs.Append(CreateParagraph());
            }

            return cd;
        }

Can I create it if I'll use the following algorithm?

Code: Select all
IAutoShape shape = slide.Shapes.AppendShape(ShapeType.Rectangle, new RectangleF(50, 100, 100, 50));

shape.ShapeStyle.LineColor.Color = Color.Red;

//Effect
PresetShadow shadow = new PresetShadow();
shadow.Preset = PresetShadowValue.FrontRightPerspective;
shadow.Distance = 10.0;
shadow.Direction = 225.0f;
shape.EffectDag.PresetShadowEffect = shadow;


Can I merge it with my code structure?

Code: Select all
  public static ChartDataLabel Add(this ChartDataLabelCollection dataLabels, int paragraphs)
        {
            var cd = dataLabels.Add();

            cd.LabelValueVisible = true;
            cd.TextFrame.Paragraphs.Clear();

           
            cd.Fill.FillType = FillFormatType.Solid;
            cd.Fill.SolidColor.Color = Color.FromArgb(0x99, Color.WhiteSmoke);
     

            cd.Line.FillFormat.FillType = FillFormatType.Solid;
            cd.Line.FillFormat.SolidFillColor.Color = Color.Black;


            cd.TextFrame.Paragraphs.Append(CreateHeader());

            for (int i = 1; i < paragraphs; i++)
            {
                cd.TextFrame.Paragraphs.Append(CreateParagraph());
            }

            return cd;
        }

Dear rokaf,

Thanks for your inquiry.
After an in-depth investigation, we found a way to set the shadow of the data lable.
Please refer to the below code.
Code: Select all
cd.Effect.PresetShadowEffect = new PresetShadow();
cd.Effect.PresetShadowEffect.ColorFormat.Color = Color.Red;           
cd.Effect.PresetShadowEffect.Distance = 10.0f;
cd.Effect.PresetShadowEffect.Direction = 225.0f;

Thank you!
But I still didn't get how to set shadow size, can you help me?
I need to create this shadow using code(check shadow.png).
For now I've successfully created shadow with needed blur and transparency:
Code: Select all
            cd.Effect.OuterShadowEffect = new OuterShadowEffect();
            cd.Effect.OuterShadowEffect.ColorFormat.Color = Color.FromArgb(99,154,154,154);
            cd.Effect.OuterShadowEffect.BlurRadius = 5;

How can I create point like this?(point jpg)

And maybe there are any extra ways to make datalabel look like rectangle with rounded corners? For example using picture or something? (shape.jpg)
