***
KNOWN PROBLEMS: the code could be cleaner, the PieChart needs a bit more work...

_No need to restart hass every time you change an option. To test your changes just refresh the page - clear your cache or use a new incongnito window if no change is observed_
***

## Features
* **Can be used standalone of HASS**;
* Updates in real time;
* Sortable by name or value;
* Chart type can be changed on the fly (3 default options: column, bar, piechart - more can ba added;
* Supports one more more entities (recomended to compare: power, temperature, humidity, mold etc.).
* Could be also use as a weather forecast (disabling some of the options might be needed).
* Highly customizable (styling, axes types, annotations etc.). Visit [Google Charts](https://developers.google.com/chart/interactive/docs/gallery) for more information and options ([ColumnChart](https://developers.google.com/chart/interactive/docs/gallery/columnchart), [BarChart](https://developers.google.com/chart/interactive/docs/gallery/barchart), [PieChart](https://developers.google.com/chart/interactive/docs/gallery/piechart)).
* The height of the chart can be set in the `options` section in `googlechart.html`

## Installation
* Download `/www/google_chart/googlechart.html` to `<your-hass-configuration-dir>/www/google_chart/` (create the folder structure if you don't have it - mind the permissions). JQuery, loader.js (google charts loader) and lodash.js (simplifies working with arrays) are also needed.
* Add it to your lovelace configuration e.g.:
```yaml
      - type: iframe
        url: /local/custom_ui/charts/googlechart.html
        aspect_ratio: 90%
```
**Main idea.**
1. Add your HASS URL and Long-Lived Access Token (get it from your profile).
```javascript
       ws = new WebSocket('wss://your_ip_or_url/api/websocket');
```
```javascript
       ws.send(JSON.stringify({"type": "auth","access_token": "Long-Lived-Access-Token"}));
 ```
2. Add your entities as variables in the designated sections.
```javascript
       var router, fridge, laptop, boiler, tv, pc, oven, washer, other, monitor;
```
```javascript
       window.router = JSON.parse(event.data)["result"].filter(function (el) { return el.entity_id == "sensor.router_power"})[0].state;
       window.fridge = JSON.parse(event.data)["result"].filter(function (el) { return el.entity_id == "sensor.fridge_power"})[0].state;
       window.laptop = JSON.parse(event.data)["result"].filter(function (el) { return el.entity_id == "sensor.laptop_power"})[0].state;
       ...
 ```
 ```javascript
        //Set value
        graph["data"].setValue(0, 1, router);
        graph["data"].setValue(1, 1, fridge);
        ...
 ```
  ```javascript
         //Set annotation
         graph["data"].setValue(0, 2, router);
         graph["data"].setValue(1, 2, fridge);
         ...
 ```
  ```javascript
         //Set name
         graph["data"].setValue(0, 0, 'Router');
         graph["data"].setValue(1, 0, 'Fridge');
         ...
 ```
 3. Lots of options to change (a lot more can be added):
 ```javascript
      var options = {
        title: "Instant power in W",
        height: 300,                                     //chart heigh in pixels
        bar: {groupWidth: '69%'},                        //bar/column width - 69% is the golden ratio
        legend: { position: 'none'},                     //if enabled the chartArea option should be modified
        titleTextStyle: {fontSize: 13, bold: false},
        chartArea: {left:35,top:25,right: 5, width:'100%',height:'82%'},
        tooltip: {trigger: 'selection'},                // 'focus'/'selection'/'none'
        vAxis: {minorGridlines: {count: 2, color: '#F4F4F4'}, gridlines: {count: 6}},       //for the column chart 
        hAxis: {minorGridlines: {count: 2, color: '#F4F4F4'}, gridlines: {count: 6}},       //font the bar chart
        // just a commnent for the vAxis/hAxis - if gridlines: {count: x} is set to x=-1(auto) the axis maximum value will change and the chart bars will be most of the time static. I recomend setting it to 5 or more.
        dataOpacity: 0.9,
        fontSize: 11,                                   //font size throughout the chart
        pieHole: 0.4,                                   //from pie to donut - comment or set to 0 to change to pie 
        pieSliceText: 'label',                          //'percentage', 'value' ,'label' ,'none'
        pieSliceTextStyle: {fontSize:10},
        is3D: false,                                     // set to true for 3D pie chart
        backgroundColor: { fill: 'white' },
        //explorer: {}                                   // uncomment to enable pan and zoom in the chart - right click resets
      };
 ```
4. Set a chart refresh period in milliseconds.
```javascript
       var chartrefreshtime = 5000;
```
## How to add more then one chart
* Duplicate `googlechart.html`;
* Change options inside new file;
* Add new iframe in lovelace;

## Changelog
```
2018.Feb.08:
- Some code cleaning. 
- Updated parseInt() to parseFloat().
2019.Jan.09:
- Added websocket version. Will go obsolete when the legacy password will be removed. Same approach for installation inside Home Assistant. The html will also work independetly - without Home Assistant. Just add your IP and legacy password.
