Hi,

How to apply different colors for uptrend and down trend in line (column) chart

(eg)For the upward line chart the color should be red and for downward chart it should be green


when the chart is a straight line(not up or down) the color should be white

Hi Sivaprasad,

Thank you for using Syncfusion products.

I have applied different colors for up and down trend in line chart. Please refer to the following code snippet.

[ C# ]
void series1_PrepareStyle(object sender, ChartPrepareStyleInfoEventArgs args)
{
ChartSeries series = sender as ChartSeries;
if (series != null&& args.Index < series.Points.Count -1)
{
if (series.Points[args.Index].YValues[0] == series.Points[args.Index+1].YValues[0])
args.Style.Interior = new Syncfusion.Drawing.BrushInfo(Color.White );
else if (series.Points[args.Index].YValues[0] < series.Points[args.Index+1].YValues[0])
args.Style.Interior = new Syncfusion.Drawing.BrushInfo(Color.Red);
else
args.Style.Interior = new Syncfusion.Drawing.BrushInfo(Color.Green );

}

}

Also kindly take a look at the attached sample.
