đź“– Afaqy Knowledge Base / AVL / Dashboard / Charts
The Charts section is a visual analytics layer built directly on top of Statistics data. It does not introduce new metrics; instead, it transforms tabular statistics into interactive visual insights exactly as shown in the UI and video.
Chart Types
Charts are grouped by analytical purpose. Each chart card represents a single statistical question.
Performance Charts
Used to measure operational efficiency and behavior over time.
Examples:
- Average Performance – Fuel Consumption
- Aggregated fuel consumption across selected units
- Displayed as a bar or column chart
- Supports hierarchical drill‑down (Level 1 → Level 2)
- Round Trip Count per Geofence
- Number of completed trips within defined geofences
- Displayed as a table or chart depending on configuration
Chart Interactions
Charts are interactive and support:
- Hover tooltips for exact values
- Drill‑down navigation (when hierarchical levels exist)
- Switching between chart and list/table view (where applicable)
Status & Activity Charts
Used to visualize availability and reporting behavior.
Examples:
- Online Units vs offline trends
- Reporting activity frequency
- Alert generation over time
Chart Header Information
Each chart card includes a standardized header containing:
- Chart title (e.g. Average Performance – Fuel Consumption)
- Metric scope (e.g. All selected units)
- Date range applied to the chart
This ensures charts remain auditable and context‑aware, especially when exported or shared.
Charts are typically used by managers and analysts to quickly understand performance, trends, and distribution without scanning large tables.
Creating a chart
The following steps explain how to create a chart and configure its data, layout, and visualization options.
- Open the Charts Module
- From the main menu, go to Dashboard → Charts.
- Click Add to create a new chart.
- Select Units
- In the Units panel, browse or search for the required units.
- Expand unit groups if needed.
- Select the checkbox next to each unit you want to include in the chart.
- Choose the Chart Type
- From the Chart Type dropdown, select Mileage.
- Define the Date Range
- In the Date section, select one of the predefined options:
- Today
- Yesterday
- Week
- Month
- Alternatively, select Specified Interval and manually set:
- From date and time
- To date and time
- Set the Data Range
- Under Data Range, choose one of the following:
- Top Ten Selected to display only the top 10 results
- All Selected to display all selected units
- Select the Chart Visualization
- In the Type section, choose how the data is displayed:
- Bar
- Doughnut
- Pie
- Configure the Layout Size
- Under Layout size, select One column.
- Apply Geofence Filters (Optional)
- From the Geofences dropdown, select one or more geofences to filter the chart data.
- Configure the X-Axis
- In X Axis Configuration, select Unit Name to display unit names on the horizontal axis.
- Set Mileage Limits
- In the Mileage section:
- Enter a Min value (in KM) to define the minimum mileage.
- Optionally, enter a Max value to limit the maximum mileage displayed.
- Save the Chart
- Click Save to create and add the chart to the dashboard.
Charts Tools
Each chart includes a standardized toolset in the top‑right corner. These tools behave consistently across all charts.
Chart View
Displays the data as a graphical chart (bar, line, etc.).
Change Chart Type
Allows switching the visualization type for the same dataset, such as:
- Bar chart
- Line chart
- Column chart
- Pie chart (where applicable)
The underlying data remains unchanged; only the visual representation is affected.
Export
Exports the chart’s underlying data to Excel, respecting:
- Selected date range
- Unit / group filters
- Status filters
Table View Icon
Switches the visualization into a detailed tabular list representing the same dataset.
Toggle Chart Layout Size
Changes the layout of the chart container, allowing users to switch between:
- Standard embedded view
- Expanded / wide layout (for better readability)
- Full‑screen mode (if enabled)
This is especially useful for charts with large datasets or wide tables.
More Options
Provides additional chart‑specific actions, such as:
- Full‑screen view
- Reset filters (chart‑level)
- Configuration options (if permitted)
Export Rules
- Exports always reflect current chart state
- Drill‑down level is preserved in the export
- Exported data matches table view exactly
Operational Use Cases
- Management performance reviews
- Trend and anomaly detection
- Operational KPI tracking
- Visual reporting for stakeholders
Statistics remains the primary analytical foundation of the system, while Charts act as its visual interpretation layer.
