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

use antishov\Morris;
use yii\web\JsExpression;

echo Morris\Line::widget([
     'resize' => true,
     'gridTextSize' => 11,
     'element' => 'lineChart',
     'data' => [
         ['date' => '2017-06-14', 'value' => 2],
         ['date' => '2017-06-15', 'value' => 4],
         ['date' => '2017-06-16', '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).

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).

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

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).

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).

barColors - Array containing colors for the series bars.
