Installation

HighchartsSt has been tested and used in Pharo, GemStone/S 64 and VA Smalltalk, but should likely work in other dialects too.

The builder (the tool that auto-generates the code), however, only works on Pharo.

Prerequisites

By default we load the stable version of Seaside, but the wrapper will likely work on any Seaside 3 version. So you can lock the Seaside baseline to whatever version you're using.

Basic Installation

You can load the framework with (change master to some released version if you wan't a pinned version):

Metacello new
	baseline: 'HighchartsSt';
	repository: 'github://ba-st/HighchartsSt:master/repository';
	load.

Loading groups

There's several groups to choose when loading:

• Highcharts will load the runtime support for Highcharts
• Highstock will load the runtime support for Highstock
• Tools will load the code generation tool
• Development will load all the packages including the tests and the code generation tool

Getting Started

To have Highcharts working, the only thing you must do is to register the wanted HighchartsLibrary into your app root class (notice there are 3 possible subclasses of it). Example:

yourApp
		addLibrary: JQDevelopmentLibrary;
		addLibrary: Highcharts6OnlineLibrary.

Then you can render a basic chart like this:

renderBarGovermentComputersChartOn: html

	| chart series data |

	data := OrderedCollection new
		add: (ChartDatum belongingTo: 'Facebook' withValue: 515333);
		add: (ChartDatum belongingTo: 'YouTube' withValue: 178001);
		add: (ChartDatum belongingTo: 'GMail' withValue: 154504);
		add: (ChartDatum belongingTo: 'Twitter' withValue: 184083);
		add: (ChartDatum belongingTo: 'Amazon' withValue: 100762);
		add: (ChartDatum belongingTo: 'Pandora' withValue: 78868);
		yourself.
	series := ChartSeries named: 'John' composedOf: data.

	html text: 'chart: '.
	chart := html highcharts newChart.
	chart yAxis title text: 'Visits'.
	chart legend enabled: false.
	chart chart type: 'column'.
	chart title text: 'Sites visited on D.C. government computers'.
	chart subtitle text: 'Source: District of Columbia'.
	chart xAxis title text: 'Site'.
	chart xAxis type: 'category'.
	chart plotOptions column colorByPoint: true.
	chart plotOptions column dataLabels enabled: true.
	(chart addSeriesForType: 'column')
		index: 0;
		name: series name;
		data: (series dataAsPointsOn: html).
	html div script: chart

The default installation of Highcharts includes some examples. You can start your Seaside adaptors, for example like this:

(ZnZincServerAdaptor port: 9999)
   	codec: GRPharoUtf8Codec new;
   start.

And then watch the live examples with your browser in http://localhost:9999/HighchartsDemo

Running the tests

Tests are auto-generated for the auto-generated code. These are under the packages HighchartsStV6-Tests and HighstockStV6-Tests. We warned that there's more than 40K test so it will take a while to run, and later be shown in the Test Runner.

Future work

Besides the issues, the following are also desired features:

• Support Highmaps
• Improve documentation
• Improve CI Support to test independently the several groups available
• Deploy the examples to the cloud
• Automatically propose Pull Requests when new versions of Highcharts are available

Authors

• The Mercap Team and Maximiliano Tabacman for the original implementation.
• The Quuve Team and Mariano Martinez Peck for the Pharo port and further development and improvements.
