text display in graph

[abc]

I am using syncfusion version 5.2. In my column graph i want that the text should be displayed inside the column and at the top of the column.

I am able to display text at only one point either inside or at top....but i want to display text at both points.

Image of what exactly i want is also attached with this message.

I will be very thankful if anyone could help me with this.

Hi Prabhjeet,

Thanks for the screenshot. It is possible to display text both inside as well as in the top of the column by handling the ChartAreaPaintEvent Handler as given below:

Sample Code:

void chartControl1_ChartAreaPaint(object sender, PaintEventArgs e)
{

if (this.checkBox1.Checked)
{
float y2 = this.chartControl1.PrimaryYAxis.GetCoordinateFromValue(this.chartControl1.PrimaryYAxis.Range.Min);

for (int i = 0; i < this.chartControl1.Series[0].Points.Count; i++)
{
ChartStyleInfo style = this.chartControl1.Series[0].Styles[i];
string s = String.Format("{0:n0}", this.chartControl1.Series[0].Points[i].YValues[0] / this.totalYValue * 100).ToString() + "%";
SizeF sz = e.Graphics.MeasureString(s, style.GdipFont);
float StartX = this.chartControl1.PrimaryXAxis.GetCoordinateFromValue(this.chartControl1.Series[0].Points[i].X) - sz.Width / 2;
float StartY = this.chartControl1.PrimaryYAxis.GetCoordinateFromValue(this.chartControl1.Series[0].Points[i].YValues[0]);
float MiddleY = y2 - StartY;
e.Graphics.DrawString(s, style.GdipFont, new SolidBrush(Color.Black), new PointF(StartX, StartY + (MiddleY / 2) - sz.Height / 2));

}
}

I have attached sample that illustrates the same in this link below.
