Introduction

Map

  • The Map tab provides a colored map that visualizes the overall performance data of each province. Move the pointer over a province on the map to view the performance metric data of the province.
  • The Statistical Data section provides the overall performance metric data of monitoring locations. For more information about metrics, see the Metrics section.
  • The Detailed Data section provides the detailed performance metric data of monitoring locations. For more information about metrics, see the Metrics section.

Analysis chart

  • The Analysis Chart tab provides a horizontal bar chart that visualizes performance metric data of carriers. Move the pointer over a horizontal bar to view the data of specific performance metrics.
  • The Statistical Data section provides the overall performance metric data of monitoring locations. For more information about metrics, see the Metrics section.
  • The Detailed Data section provides the detailed performance metric data of monitoring locations. For more information about metrics, see the Metrics section.

Trend chart

  • The Trend Chart tab provides a line chart that visualizes performance metric data of carriers. Move the pointer over a point along the line to view the data of specific performance metrics.
  • The Statistical Data section provides the overall performance metric data of monitoring locations. For more information about metrics, see the Metrics section.
  • The Detailed Data section provides the detailed performance metric data of monitoring locations. For more information about metrics, see the Metrics section.

Region chart

  • The Region Chart tab provides a horizontal bar chart that visualizes performance metric data of carriers. Move the pointer over a horizontal bar to view the data of specific performance metrics.
  • The Statistical Data section provides the overall performance metric data of monitoring locations. For more information about metrics, see the Metrics section.
  • The Detailed Data section provides the detailed performance metric data of monitoring locations. For more information about metrics, see the Metrics section.

Scatter chart

  • The Scatter Chart tab provides a scatter chart that visualizes performance metric data of carriers. Move the pointer over a point in the scatter chart to view the data of specific performance metrics.
  • The Statistical Data section provides the overall performance metric data of monitoring locations. For more information about metrics, see the Metrics section.
