# Axis Grid Lines

## Content



Grid lines are lines that appear perpendicular with major/minor tick marks at unit major/minor intervals. The lines that are placed coincident with major tickmarks at UnitMajor intervals are controlled by the [MajorGrid](/componentone/api/win/online-chart3d/dotnet-framework-api/C1.Win.C1Chart3D.4.8/C1.Win.C1Chart3D.Chart3DAxis.MajorGrid.html) property. Grid lines can help improve the readability of the Chart when you are looking for exact values. The major grid lines appearances are controlled by the [Chart3DGridLines](/componentone/api/win/online-chart3d/dotnet-framework-api/C1.Win.C1Chart3D.4.8/C1.Win.C1Chart3D.Chart3DGridLines.html) properties.

To set grid lines on the XY-plane

Set the [IsOnXYPlane](/componentone/api/win/online-chart3d/dotnet-framework-api/C1.Win.C1Chart3D.4.8/C1.Win.C1Chart3D.Chart3DGridLines.IsOnXYPlane.html) property to true for the grid lines to appear on the XY-Plane.

To set grid lines on the XZ-plane

Set the [IsOnXZPlane](/componentone/api/win/online-chart3d/dotnet-framework-api/C1.Win.C1Chart3D.4.8/C1.Win.C1Chart3D.Chart3DGridLines.IsOnXZPlane.html) property to true for the grid lines to appear on the XZ-Plane.

To set grid lines on the YZ-plane

Set the [IsOnYZPlane](/componentone/api/win/online-chart3d/dotnet-framework-api/C1.Win.C1Chart3D.4.8/C1.Win.C1Chart3D.Chart3DGridLines.IsOnYZPlane.html) property to true for the grid lines to appear on the YZ-Plane.

Grid lines appearance

You can determine the style for the major grid lines through the [Style](/componentone/api/win/online-chart3d/dotnet-framework-api/C1.Win.C1Chart3D.4.8/C1.Win.C1Chart3D.Chart3DGridLines.Style.html) property which returns the **Chart3DLineStyle** object that allows you to customize the grid lines color, pattern, or thickness.
