Axis in Blazor Smith Chart component

28 Jul 2021 / 4 minutes to read

Smith Chart supports two different types of axes. They are:

  • Horizontal Axis - The axis is drawn as a straight line in the horizontal direction of the Smith Chart.
  • Radial Axis - The axis is drawn as a circular path.

Labels Customization

Axis labels are used to indicate what type of data is bound for the Smith Chart. The use of axis labels makes it easy to determine at which interval chart is being rendered. The axis labels for the horizontal and radial axes can be customized using the properties listed as following.

Smith chart axis label customization

Gridlines

Gridlines on the horizontal and the radial axes can be used to make data in a chart easier to see. Gridlines extend from any horizontal or radial axis around the plot area of the Smith Chart. Both the horizontal and radial axes support major and minor gridlines. Major gridlines are drawn from the position in which the labels are rendered. Minor gridlines are drawn between two major gridlines using the Count property in the minor gridlines.

The following properties can be customized in both the major and minor gridlines.

  • Width - Used to customize the width of the gridlines.
  • DashArray - Used to customize whether the gridline has to render as normal line or dashed line.
  • Visible - Used to enable or disable the visibility of the gridlines.
  • Opacity - Used to customize the opacity of the major gridlines.
  • Color - Used to customize the color of the major gridlines.
  • Count - Used to customize the count of the minor gridlines.
