# Trends on mobile

> Select source forms, chart points in Trends View, apply filters, and save views on the KODE OS mobile app.

Chart a point's recent history to spot a drift before it becomes a fault. Pick one or more points, then open `Trends View` for synchronized charts. Adjust the time range and interpolation, and save the view for yourself or your building team. This page follows [Trends](/products/kode-os/trends) on the web.

## Open Trends

Reach `Trends` from the building app launcher, equipment menus, system points, or search when enabled.

## Select points to chart

The `Trends` home screen lists point entries. Each row shows the point name with the device name below and a label for the device origin—virtual or original.

Use `Clear All`, then `Apply` to refresh the list.

## Trends View

Select the points you want to trend from the [Trends home screen](#select-points-to-chart), then tap `Trends View` on the bottom bar.

`Trends View` shows stacked charts that share one time axis. Numeric series appear on the top chart; boolean or state series appear on the lower chart.

### Header controls

| Control       | Purpose                                             |
| ------------- | --------------------------------------------------- |
| Back          | Return to source selection                          |
| `Save View`   | Name and optionally publish the current chart setup |
| Interpolation | Smooth between samples when `On`                    |
| Time range    | Preset or custom window (dropdown)                  |

<div className="flex justify-center w-full my-4">
  <Frame className="w-fit mx-auto" caption="Yesterday with interpolation on">
    <img className="mx-auto block h-auto max-w-[400px] w-full" src="https://mintcdn.com/kodelabs/MYYnSdKhTqQf34f4/images/mobile-app/kode-os-mobile-trends-view-yesterday.png?fit=max&auto=format&n=MYYnSdKhTqQf34f4&q=85&s=9c13758a3e37bdad4f1cf5c46ead8a89" alt="Trends View with numeric and AHU_1 fan state chart for Yesterday" width="400" height="867" data-path="images/mobile-app/kode-os-mobile-trends-view-yesterday.png" />
  </Frame>
</div>

### Legend and pagination

Below the controls, `Left Axis` lists active series (for example, `AHU_1, NumericSwitch` and `AI`). Use `1/2` arrows when more series exist than fit on screen.

### Numeric chart

* Y-axis shows engineering values (for example, 7.5–9.6)
* Multiple series may render as dense bands when sampling is fast
* Pinch or use the bottom range slider to pan and zoom time

<div className="flex justify-center w-full my-4">
  <Frame className="w-fit mx-auto" caption="Last 2 Days spans multiple dates on the X-axis">

  </Frame>
</div>

### State / boolean chart

The lower chart shows boolean or enum-style points (for example, an AHU fan status) as horizontal bars. A toggle above the chart may label the current state (`Off` in the screenshot).

### Time range presets

Tap the time dropdown to change the window.

| `Last 30 Days` / `This Month` | Weekly reviews                           |
| `Custom Range`                | Exact start and end for an investigation |

Select `Close` to return to the chart.

## Save a view

Tap `Save View` to store the current points, range, and interpolation settings.

| `Name`   | Label for the saved view (required)                              |
| `Public` | When checked, others assigned to the building can open this view |

Saved views complement [Bookmarks](/products/mobile-app/get-started/bookmarks) for personal shortcuts; public views behave like lightweight shared templates on mobile.
