+yii2-morrisjs
+===================
+
+This is the [MorrisJS](http://morrisjs.github.io/morris.js/index.html) widget. It's a very simple API for drawing line and bar charts.
+
+## Installation
+
+The preferred way to install this extension is through [composer](http://getcomposer.org/download/). Check the [composer.json](https://github.com/antishov/yii2-morrisjs/blob/master/composer.json) for this extension's requirements and dependencies.
+
+To install, either run
+
+```
+$ composer require antishov/yii2-morrisjs
+```
+
+or add
+
+```
+"antishov/yii2-morrisjs": "@stable"
+```
+
+to the `require` section of your `composer.json` file.
+
+## Usage
+
+### Line Chart
+
+#### Example of code
+```php
+use antishov\Morris;
+use yii\web\JsExpression;
+
+echo Morris\Line::widget([
+     'resize' => true,
+     'gridTextSize' => 11,
+     'element' => 'lineChart',
+     'data' => [
+         ['date' => '14/06/2017', 'value' => 2],
+         ['date' => '15/06/2017', 'value' => 4],
+         ['date' => '16/06/2017', 'value' => 1]
+     ],
+     'xKey' => 'date',
+     'yKeys' => ['value'],
+     'labels' => ['Impressions'],
+     'xLabels' => 'day',
+     'yLabelFormat' => new JsExpression(
+         'function (y) {if (y === parseInt(y, 10)) {return y;}else {return "";}}'
+     ),
+     'yMin' => 'auto 40',
+     'lineColors' => ['rgb(123, 204, 221)'],
+     'pointFillColors' => ['rgb(82, 188, 211)'],
+ ]);
+```
+
+#### Properties
+`resize` - Set to `true` to enable automatic resizing when the containing element resizes. (default: `false`). This has a significant performance impact, so is disabled by default.
+
+`gridTextSize` - Set the point size of the axis labels (default: `12`).
+
+`element` - Identifier that will be assigned to the chart.
+
+`data` - The data to plot. This is an array of objects, containing x and y attributes as described by the xkey and ykeys options. 
+
+`xKey` - A string containing the name of the attribute that contains date (X) values (see available formats at [spec](http://morrisjs.github.io/morris.js/lines.html)).
+
+`yKeys` - A list of strings containing names of attributes that contain Y values (one for each series of data to be plotted).
+
+`labels` - A list of strings containing labels for the data series to be plotted (corresponding to the values in the `ykeys` option).
+
+`xLabels` - Sets the x axis labelling interval. By default the interval will be automatically computed  (see valid interval strings at [spec](http://morrisjs.github.io/morris.js/lines.html)).
+
+`yLabelFormat` -  function that accepts y-values and formats them for display as y-axis labels.
+
+`yMin` - Min. bound for Y-values. Alternatively, set this to `'auto'` to compute automatically, or `'auto [num]'` to automatically compute and ensure that the min y-value is at most `[num]`.
+
+`lineColors` - lineColors	Array containing colors for the series lines/points.
+
+`pointFillColors` - Colors for the series points. By default uses the same values as `lineColors`.
+
+
+### Bar Chart
+
+``` php
+use antishov\Morris;
+use yii\web\JsExpression;
+
+echo Morris\Bar::widget([
+     'element' => 'barChart',
+     'data' => [
+         ['date' => '2017-06-14', 'value' => 2.36],
+         ['date' => '2017-06-15', 'value' => 0.79],
+         ['date' => '2017-06-16', 'value' => 9.99]
+     ],
+     'xKey' => 'date',
+     'yKeys' => ['value'],
+     'labels' => ['Revenue'],
+     'barColors' => ['rgb(82, 188, 211)', 'rgb(49, 167, 193)'],
+ ]);
+```
+#### Properties
+`element` - Identifier that will be assigned to the chart.
+
+`data` - The data to plot. This is an array of objects, containing x and y attributes as described by the xkey and ykeys options. 
+
+`xKey` - A string containing the name of the attribute that contains date (X) values (see available formats at [spec](http://morrisjs.github.io/morris.js/lines.html)).

+
+`labels` - A list of strings containing labels for the data series to be plotted (corresponding to the values in the `ykeys` option).
+
+`barColors` - Array containing colors for the series bars.
