Question

I want my chart backgroud line will be dotted. Which property can i use for dotted in syncfusion? I tried but i coudn't do this. I don't know exactly which propertly will use for dotted line.
Here is my code:
control.AutoTempFileCleanUp = true;
control.OutputFormat = ImageProviderOutputFormat.DiskFile;
control.Model.Series.Clear();
ChartModel chartModel = new ChartModel();
ChartSeries chart = new ChartSeries(yAxisBar1LegendName, ChartSeriesType.Column);
chart.Text = yAxisBar1LegendName;
control.ChartArea.PrimaryXAxis.TickLabelsDrawingMode = ChartAxisTickLabelDrawingMode.UserMode;
// = string.Format("");
control.ChartArea.PrimaryXAxis.Labels.Add(new ChartAxisLabel("", Color.Black, new Font("Arial", 10), 0, "", ChartValueType.Custom));
int counter = 1;
DoubleRange dr = new DoubleRange(1, 100);
foreach (DataRow row in ds.Tables[0].Rows)
{
double bar1Value = Convert.ToDouble(row[yAxisValueColumn1]);
chart.Points.Add(counter, bar1Value);
control.ChartArea.PrimaryXAxis.Labels.Add(new ChartAxisLabel(row["ModuleCode"].ToString(), Color.Black, new Font("Arial", 10), counter, "", ChartValueType.Custom));
counter++;
}
chart.PrepareStyle += new ChartPrepareStyleInfoHandler(series_PrepareStyle);
control.ChartArea.PrimaryXAxis.DrawGrid = false;
control.PrimaryXAxis.GridLineType.ForeColor = Color.DarkGray;
control.PrimaryYAxis.GridLineType.ForeColor = Color.DarkGray;
control.PrimaryXAxis.LineType.ForeColor = Color.DarkGray;
control.PrimaryYAxis.LineType.ForeColor = Color.DarkGray;
control.Text = chartHeader;
control.ChartArea.PrimaryYAxis.Title = yAxisText;
control.ChartArea.PrimaryXAxis.Title = xAxisText;
control.ChartArea.PrimaryXAxis.TitleAlignment = StringAlignment.Center;
control.ChartArea.PrimaryXAxis.IsVisible = true;
control.ChartArea.PrimaryXAxis.LabelAlignment = StringAlignment.Center;
control.ChartArea.PrimaryXAxis.VisibleRange.Min = 0;
control.ChartArea.PrimaryXAxis.VisibleRange.Max = counter;
control.ChartArea.PrimaryXAxis.VisibleRange.Interval = 1;
control.ChartArea.PrimaryYAxis.EdgeLabelsDrawingMode = ChartAxisEdgeLabelsDrawingMode.Center;
control.ChartArea.PrimaryYAxis.GridDrawMode = ChartAxisGridDrawingMode.Default;
//control.PrimaryXAxis.EdgeLabelsDrawingMode = ChartAxisEdgeLabelsDrawingMode.Center;
control.PrimaryXAxis.Font = new Font("Arial", 10F);
control.PrimaryYAxis.Font = new Font("Arial", 10F);
counter = 0;
foreach (ChartSeries series in control.Series)
{
Color color;
if (counter == 0)
{
color = Color.Green;
else
{
color = Color.Red;
}
series.Style.Interior = new BrushInfo(color);
series.Style.Border.Color = Color.DarkGray;
series.Style.Font.Bold = true;
series.Style.TextColor = Color.Black;
series.Style.TextOrientation = ChartTextOrientation.Left;
series.Style.TextFormat = "{0}";
counter++;
}
control.Width = 650;
control.Series3D = false;
control.ShowLegend = false;
control.BorderStyle = BorderStyle.None;
control.BorderAppearance.SkinStyle = ChartBorderSkinStyle.None;
//control.Legend.Alignment = ChartAlignment.Far;
}
Here is my chart image:

Thanks for using syncfusion products.
We have analyzed your query. If you want to customize the grid lines in axis, then you can use the “DashStyle” property in GridLineType which property is used to change the line style. And you can also specify the grid line style as Dash, DashDot, DashDotDot, Dot, Solid in axis.
And please find the below code snippet
this.ChartWebControl1.PrimaryYAxis.GridLineType.DashStyle = System.Drawing.Drawing2D.DashStyle.DashDot;
And we have also prepared a sample for your reference in ASP.NET classic platform and attached in the below location.

Please find the output of the sample below:
And also we wish to let you know that the above mentioned property is also applicable for chart control in windows forms, ASP.NET classic and ASP.NET MVC classic platforms.
