Cannot remove X Axis grid-lines for XYDiagram bar chart

created 8 years ago

Hello,

I am experiencing an issue trying to remove all the grid lines from my bar chart. It's a simple 2D bar chart and I've tried the following code to remove the vertical line that appears in each grouping which you can see in the attached image.

C#
( (BarSeriesView)ChartControl.SeriesTemplate.View ).AxisX.GridLines.Visible = false;

I've also tried this:

C#
XYDiagram diagram = (XYDiagram)ChartControl.Diagram;  
diagram.AxisX.GridLines.Visible = false;  
diagram.AxisX.GridLines.MinorVisible = false;  
diagram.AxisX.Tickmarks.Visible = false;  
diagram.AxisX.Tickmarks.MinorVisible = false;  
diagram.AxisX.Interlaced = false;

I was able to remove all the Y-Axis grid lines just fine using the same code above, but of course changing AxisX to AxisY.

Looking forward to your response,
Thanks.

Hello Yuvraj,

ChartControl generates series and diagrams when drawing the content. The proper way to customize the diagram in this case is to handle the BoundDataChanged event. It occurs every time a chart control generates its series points from the underlying data source:

C#
private void chartControl1_BoundDataChanged(object sender, EventArgs e)  
{  
    XYDiagram diagram = (sender as ChartControl).Diagram as XYDiagram;  
    if (diagram == null) return;  
     diagram.AxisX.GridLines.Visible = false;  
    diagram.AxisX.GridLines.MinorVisible = false;  
    diagram.AxisX.Tickmarks.Visible = false;  
    diagram.AxisX.Tickmarks.MinorVisible = false;  
    diagram.AxisX.Interlaced = false;  
}
