Charts and summary figures
The Charts tab plots the active cat’s readings and doses over a chosen time range: a Glucose Levels line chart with the target range as dashed lines, an Insulin Doses bar chart, the Expected Insulin Activity estimate (its own page: the insulin activity curve), and a Summary of four plain figures. Tap either chart to open it full screen and pan or zoom. The Report button in the top right builds the PDF report for the range on screen. Everything redraws as soon as you save an entry.
There is no combined glucose-plus-insulin overlay: the two series are always separate charts, one above the other.
Choosing the time range
Section titled “Choosing the time range”The segment control at the top offers 24h, 7 days, 30 days, 90 days and Custom. Each ends now and reaches back that far. The one selected when you open the tab is the Default Time Range from Settings › Chart Settings (7 days unless you changed it); picking a different one here lasts for the session.
Custom opens a Custom Date Range sheet with a start and end date (dates only — the range covers whole days from the start of the first to the end of the last). Apply draws it; Cancel drops back to 7 days. While Custom is selected the chosen dates and a Change button sit under the segment control.
If the range holds nothing at all the tab shows No Data Available — Start tracking glucose and insulin to see charts. If it holds one series but not the other, the empty chart says No glucose data available or No insulin data available in its place.
The Glucose Levels chart
Section titled “The Glucose Levels chart”A red line joining red points, one per reading, in your glucose unit. Two dashed horizontal lines mark the cat’s target range: green at the target minimum and orange at the target maximum. Readings between them fell inside the range. The chart plots only what you entered — it does not estimate values between readings, and it draws no trend line. Tick spacing follows the range (every 4 hours at 24h, daily at 7 days, every 5 days at 30, fortnightly at 90).
The Insulin Doses chart
Section titled “The Insulin Doses chart”One blue bar per dose; bar height is the units. The vertical axis scales to your largest dose (never lower than 5 units), so ordinary 1–6-unit cat doses fill the chart. A gap means nothing was recorded then, which is not the same as a dose being missed.
The four summary tiles
Section titled “The four summary tiles”Every figure is arithmetic over the entries inside the selected range and nothing more — no variability index, no trend, no score. Each tile has an ⓘ button explaining exactly this.
| Tile | Value | Shows — when |
|---|---|---|
| Average Glucose | The plain mean of every reading in the range, in your unit. Readings at different times of day weigh the same. | No readings in the range |
| Readings in Range | Readings inside the cat’s target range ÷ all readings in the range, as a percentage. It counts readings, not time — a spot check says what the value was at that moment, nothing about the hours between. | No readings, or the profile has no usable target range |
| Total Readings | How many glucose readings the range holds | — |
| Insulin Doses | How many doses the range holds | — |
Readings in Range was named on purpose: a “time in range” figure needs a continuous monitor. Two spot checks a day cannot support one, and the app does not pretend otherwise. On the largest accessibility text sizes the tiles stack one per row.
The ⓘ explanations
Section titled “The ⓘ explanations”Both charts and every tile carry an ⓘ button. For a chart it opens a sheet with two parts — What is this? (what is plotted) and Reading the chart (what each colour is; e.g. Red dots and line — readings you recorded · Green dashed line — target minimum · Orange dashed line — target maximum). For a tile it opens the one-paragraph description in the table above, with the actual target range spelled out (…inside Mochi’s target range of 80–180 mg/dL).
Full-screen view
Section titled “Full-screen view”Tap the glucose or insulin chart (or, with VoiceOver, activate it) to open it full screen — the same data, larger, with a Close button, a caption such as Showing 7 days, and a slider-icon menu. It works in landscape too.
- Drag left and right to pan through time; a flick keeps moving and coasts to a stop. Pinch to zoom around the point under your fingers.
- The window can be as short as 6 hours and as long as your data spans; it is kept over your data, so you cannot pan into empty years, and with less than a window’s worth of data the view simply centres on it.
- The menu offers Reset View, Zoom In (Less Time) (halves the window), Zoom Out (More Time) (doubles it), 6 Hours, 1 Day, 3 Days, 1 Week and All Data.
- Go to Latest appears whenever you have panned away from the newest entries; it snaps back.
- Panning to a stretch with nothing in it shows No Data in Time Range — Try zooming out or panning to see more data.
The view opens on the same span you had selected on the tab (24h → 1 day, 7 days → 1 week, and so on), positioned at the newest data.
