hGraph: Your health in one picture.
hGraph is an open source javascript library for visualizing health data.
hGraph is a React component using D3.

This package can be found on npm and installed like so:
$ yarn add hgraph-react
# or
$ npm install hgraph-reactThe hGraph component is packaged using webpack.
Most props are not required and have sensible defaults built in, as listed below.
| Prop Name | Type | Is Required | Description | Default |
|---|---|---|---|---|
| data | array | true | An array of objects representing the metrics to display in hGraph (see below) | N/A |
| score | number | false | The overall score (hScore) to display in the center of hGraph | N/A |
| width | number | false | The width in pixels hGraph should render at. | 600 |
| height | number | false | The height in pixels hGraph should render at. | 600 |
| margin | object | false | An object representing the values for margins around hGraph. | { top: 70, right: 100, bottom: 70, left: 100 } |
| thresholdMin | number | false | A number value between 0 and 1 (percentage), determining the position the lower threshold of the healthy range renders at. | .25 |
| thresholdMax | number | false | A number value between 0 and 1 (percentage), determining the position the upper threshold of the healthy range renders at. | .75 |
| donutHoleFactor | number | false | A number value between 0 and 1 (percentage), determining the amount of hGraph's radius that should be cut out forming the hole in the center of the graph. | .4 |
| color | string (hex color code) | false | The color of the points and polygon shape. | '#616363' |
| healthyRangeFillColor | string (hex color code) | false | The color of the healthy range band. | '#98bd8e' |
| fontSize | number | false | The size (in pixels) of the font for the labels. | 16 |
| fontColor | string (hex color code) | false | The color of the labels. | '#000' |
| showAxisLabel | boolean | false | Whether or not axis labels should display around hGraph. | true |
| axisLabelWrapWidth | number | false | The width (in pixels) that the labels should wrap text at. | 80 (Note: use null for no wrapping) |
| axisLabelOffset | number | false | The distance (in pixels) that axis labels should be offset from the outer bounds of hGraph's 'absolute max' radius. | 12 |
| areaOpacity | number | false | The opacity of the polygon shape. | 0.25 |
| pointRadius | number | false | The radius (in pixels) of the points for metric values. | 10 |
| pointLabelWrapWidth | number | false | The width (in pixels) that the point labels should wrap text at. | null (no wrapping) |
| pointLabelOffset | number | false | The distance (in pixels) that point labels should be offset from the point. | 8 |
| hitboxRadius | number | false | The radius (in pixels) of the point hitboxes. (hGraph overlays a transparent hitbox over each point which can help users accurately click/touch points, particularly on mobile devices.) | Defaults to props.pointRadius size. |
| showScore | boolean | false | Whether or not to display the overall score (hScore) in the middle of hGraph. | true |
| scoreFontSize | number | false | The size (in pixels) of the font for the overall hGraph score | 120 |
| scoreFontColor | string (hex color code) | false | The color of the hGraph score. | '#000' |
| zoomFactor | number | false | The multiplier factor hGraph should zoom in. | 2.25 |
| zoomTransitionTime | number | false | The amount of time (in milliseconds) the zooming animation should take. | 750 |
| zoomOnPointClick | boolean | false | Configure if hGraph should zoom in/focus on a clicked point and display child points in the graph. | true |
| onPointClick | function | false | Callback function called when a point is clicked. Function is passed 2 arguments: the data object corresponding to the point clicked, and the event. | N/A |
| Property Name | Type | Is Required | Description |
|---|---|---|---|
| id | string | true | A unique (compared to all other metrics) identifier string for the metric. |
| label | string | true | The axis display label for the metric. |
| value | number | true | The patient's recorded value for the metric. |
| healthyMin | number | true | The minimum value possible to still be considered a healthy value. |
| healthyMax | number | true | The maximum value possible to still be considered a healthy value. |
| absoluteMin | number | true | A reasonable minimum possible value for this metric. Note: values below this absolute minimum will be clamped to the min.) |
| absoluteMax | number | true | A reasonable maximum possible value for this metric. Note: values above this absolute maximum will be clamped to the max. |
| unitLabel | string | true | The units the metric is measured in, displayed with the metric value. |
| children | array | false | Optional array of child metrics that comprise this metric. Children metrics should conform to hGraph Metric Objects properties. Children are shown when a point is clicked and hGraph is in the "zoomed in" state. |
Set of health metrics to be displayed on the hGraph. A default set is provided but can be tailored to your installation.

hScore (notional)
hScore is an algorithm for scoring a person's health and can be displayed at the center of the hGraph. hScore is currently a concept and has not been developed.
For development and demo’s, we’ve used Synthea for generating synthetic patient data to display in hGraph.
