We are using UltraWinChart to generate PieCharts. Experiencing issues with pie chart when there are negative values in the dataset. It just doesn't come up. But if I try to plot the same in excel it woks fine. Does the winChart control treat negative values in a different way?
like Excel, UltraWinChart will plot the absolute value of any negative values in a Pie Chart.
this.ultraChart1.ChartType = ChartType.PieChart;this.ultraChart1.Data.DataSource = new double[] { 1, 1, 1, -1 };this.ultraChart1.Data.DataBind();
this should generate a pie with four equally sized slices.
