Chart styles, Y-axis scaling, series settings and controls for chart tiles on Orion Data dashboards.

Chart tiles are dashboard widgets that display sensor data over time. For steps on adding a tile to a dashboard, see [Add a widget to a dashboard](https://docs.oriondata.io/portal/dashboards/how-to-add-a-widget-to-a-dashboard/).

## Chart styles

When configuring a tile in the **Edit Tile** panel, the **Tile Style** selector determines how the data is displayed. Chart-style options include line graph, area chart, bar chart, scatter plot, and similar time-series visualisation styles. The tile header displays a label showing the selected chart style once the tile is saved.

Choose the style that best suits the data being displayed. Line graphs are well suited to continuous sensor readings such as water level or temperature. Area charts work well for showing cumulative or filled data such as soil moisture.

## Y-axis settings

The **Axis Options** section controls the behaviour and appearance of the Y axis for the chart tile.

### Auto vs Manual scaling

By default, the Y axis uses **Auto** scaling, which adjusts the axis range automatically based on the data present in the selected time period.

Switch to **Manual** scaling when you need to fix the axis to a specific range. This is useful when comparing tiles side by side or when you want to prevent the chart from rescaling when values fluctuate.

When **Manual** is selected, two additional fields appear:

- **Y-Axis Upper Bound** - the maximum value displayed on the Y axis
- **Y-Axis Lower Bound** - the minimum value displayed on the Y axis

### Interval

Sets the spacing between gridlines on the Y axis. Set to 0 to let the platform determine the interval automatically.

### Position

Sets which side of the chart the Y axis label appears on. **L** places it on the left and **R** places it on the right. When a tile has two series that use different units or scales, assign one series to **L** and the other to **R** to display two independent Y axes on the same chart.

### Color

Sets the colour of the Y axis line. This is useful when two Y axes are displayed, as it allows each axis to be colour-matched to its corresponding series for clarity.

### Invert Graph

The **Invert Graph** toggle flips the Y axis so that higher values appear at the bottom and lower values at the top. This is particularly useful for depth-based measurements such as depth to water, where a decreasing depth reading represents a rising water level and is more intuitively read from the top of the chart downward.

## Series settings

A chart tile must have at least one series assigned to display data. Multiple series can be added to a single tile, including data from different devices.

In the **Series** section:

1. Select the device from the series selector. The device tag will appear once selected.
2. Use the **Select Series** dropdown to choose the sensor channel to display.
3. Enter a **Label** for the series. This appears in the chart legend.
4. Assign the series to a Y axis position (**L** for left, **R** for right).
5. Select a colour for the series line or fill.
6. Select **+ Add Series** to add further series to the same tile if required.

## Tile controls

Once a chart tile is saved and visible on the dashboard canvas, each tile displays a set of controls in its top right corner:

- **Zoom Tile** - toggles a zoomed view of the tile for closer inspection of the data
- **Export data icon** - exports the data displayed in the tile
- **Camera icon** - saves a screenshot of the tile

## Summary

Chart tiles are configured using the **Edit Tile** panel by selecting a chart style, setting axis options, and assigning one or more sensor series. The Y axis can be scaled automatically or fixed to a manual range, inverted for depth-based data, and split into left and right axes when displaying series with different units. Once on the dashboard canvas, tiles can be zoomed, exported, and screenshotted using the tile controls.

## Next Steps

- Add multiple series to a single chart tile to compare sensor readings from different devices
- Use **Invert Graph** for any depth-to-water or below-ground measurement tiles
- Use **Manual** scaling when displaying tiles side by side that should share the same Y axis range
