.NET Chart Grid Lines

Scale gridlines are synchronized with the scale major and minor tick values and are used to measure and interpret the data that is displayed by the control. Gridlines appear on the plot of Cartesian, Ternary, Polar, and Radar charts. They can also appear on the chart walls in 3D Cartesian charts.

Use Grid Lines to Improve Readability
Grid lines help users estimate data values and align data points with axes.

Keep Them Subtle
Use light colors, thin or dashed lines, or partial transparency so they don’t distract the user from the data.

Alignment with Major Ticks
Align grid lines with major ticks by default to maintain a clean and readable chart plot.

Minimize Minor Grid Lines
Only include minor grid lines when they provide additional needed precision.

Enable Horizontal or Vertical Lines Selectively
For certain charts, like bar or line charts, it may be more effective to use only horizontal or only vertical grid lines.
