Configure a line layer

• Color: Set the values for MinValue Color, MaxValue Color, and NoData Color.
  • MinValue Color indicates the color of the line that has the minimum value in the value field.
  • MaxValue Color indicates the color of the line that has the maximum value in the value field.
  • NoData Color indicates the color of the line that has no value in the value field.
  If the value indicated by a line is between the maximum value and the minimum value, the color of the line is a gradient color calculated based on the value. For more information, see Configure item description.
  Note If the Color values in both the Configuration plane and the color field in the Data plane are set, the Data plane value takes effect.
• LineWidth: Set the line width by dragging the slider or entering a value.
• Dotted Line: Select a line type from the drop-down list.

• Hover: Enable or disable the hover function by clicking the Eye icon. You can set the color and width of the line displayed for the hover effect. This effect is displayed only when you preview the layer or after you release the layer.
• Click FitBounds: Select this check box to enable the focus effect for the line. After you enable this effect, the system automatically focuses the line that you have clicked. The line focus effect is displayed only when you preview the layer or after you release the layer.
• FitBounds Padding: Set the fitbounds padding of lines by dragging the slider. You must select the Click FitBounds check box before setting this parameter. The padding setting is displayed only when you preview the layer or after you release the layer.
• Callback ID: Set the field for associating data between widgets. This filed must be associated with the data of this widget, and you can only set one field for this parameter.
  Note This function is also added to the Interaction plane where you can set multiple fields. Additionally, this function will be removed from the Configuration plane. Therefore, we recommend that you upgrade the widget to the latest version.
