Graphs
Graphs let you build charts from your event data. You choose the chart type, what to measure, and the colours — EDGR pulls the data and draws it. Saved graphs can be added to your dashboard as a widget, and the data is always live against whatever time range you’re viewing.
1. Choose a chart type
The chart type determines the shape of the visualisation and what question it’s answering:
| Chart type | Best for asking |
|---|---|
| Bar (over time) | How many events happened per day, week, or month? |
| Line or area | Is this trending up or down over time? |
| Pie or donut | What proportion does each type contribute? |
| Total by type (bar) | Across the full range, which event type happened most? |
See Graph examples for rendered examples of each type.
2. Add series
Each chart is made of one or more series: a named, coloured line, bar, or slice. For each series you pick:
- Event type: which event type to count, or leave empty for all events
- Colour: the bar fill, line colour, or pie segment colour
- Label: shown in the legend
Bar and line charts support multiple series, so you can compare event types side by side. Pie charts show one slice per series.
3. Set granularity
Granularity controls how finely data is grouped — how much time each bar or point represents:
- Daily: one point per day
- Weekly: one point per week
- Monthly: one point per month
- Hourly: one point per hour (max 24-hour range)
The time range itself is not saved inside the graph — it’s set by the context (dashboard time range or the range picker on the graph viewer page). The same graph can show different data depending on where you view it.
4. Choose a layout
For bar and line charts with multiple series, you can control how they’re arranged:
- Overlap: series are drawn on the same axis, layered over each other
- Stacked: series are stacked so you can see both the individual values and the total
- 100% stacked: rescales everything so bars always add up to 100%, showing proportion rather than raw count
- Grouped: side-by-side bars per time period (bar charts only)
5. Set display options
- Cumulative: shows a running total instead of counts per period. Instead of “how many this week”, it shows “how many total so far”.
- From total: when cumulative is on, starts the running count from your all-time total before the selected range rather than from zero. Useful for a number that should just keep climbing.
- Fit y-axis: zooms the y-axis in to the range your data actually occupies, rather than always starting at zero. Most useful on cumulative charts where values start high and the daily movement is small.
- Show average: draws a dashed average line across the chart.
Saving and using graphs
- Go to Graphs and tap New graph
- Configure the chart type, series, and display options
- The preview updates live as you make changes
- Tap Save to store the graph in your library
The graph can then be added to any dashboard as a Graph widget.
Things worth knowing
Total by type shows the full range, not individual periods. The total count chart shows overall totals per event type across the entire selected range — there’s no day-by-day breakdown. Use “Bar (over time)” for that.
Pie charts are single-series per slice. One series per slice of the pie. Use “Total by type” to compare across event types in a bar format.
