Introduction

Vaadin

Vaadin is a web application framework for Java. In contrast to Javascript libraries and browser-plugin based solutions, Vaadin features a complete stack that includes a robust server-side programming model as well as client-side development tools based on GWT and HTML5.

More information: https://vaadin.com/home

jqPlot

jqPlot (http://www.jqplot.com) is a plotting and charting plugin for the jQuery Javascript framework and is dual licensed under the MIT and GPL version 2 licenses. jqPlot produces line, bar and pie charts with many features.

dCharts

dCharts is Vaadin add-on for creating charts and is a wrapper for jqPlot library.
For now dCharts support:

Bar Charts Block Charts Bubble Charts Donut Charts Line Charts
Charts Charts-01.png Charts-02.png Charts-03.png Charts-04.png Charts-05.png
Meter Gauge Charts OHLC, HLC and
Candlestick Charts
Pie Charts Pyramid Charts Waterfall Charts

To enable it in OSBP it was neccessary to add OSGi capabilities to the addon.

Chart DSL

Chart DSL generates the vaddin dCharts ui.

The main semantic elements of the ChartDSL are:

  • package - the root element that contains all the other elements. A model can contain multiple packages.
  • import declarations - used to import external models or even Java classes.
  • chart - define the chart configurations, e.g. chart type, polling time, datamart details, etc.
  • as bar/line/pie/donut/bubble/gauge/tree - define the type for this chart .
  • using datamart - define the data source details for this chart , e.g. row/column configurations, legend details and tooltips configurations.


Syntax

Package

Syntax:

package <package name>  {
    import <import models/class name>
     ...

    chart... [using datamart <datamart name>
    {
         ...
    }]
...
}

Chart

Syntax:

chart <char name> [described by <discription>] as 
    <chart type>
    [polling <polling time number>]
    [using datamart <datamart name> {
           ...
    }]

Generate a <chartame>+Chart.java file, in which a java class named <chartname>+Chart extended from java class AbstractHybridVaaclipseView is defined. In this class, chart and chart configurations are defined.

For the tree chart, generate explicit a <chartname>+<treetype>+JsChart.java file, a <chartname>+<treetype>+JsState.java file and a Treemap+<chartname>+<treetype>.js file.

The methods collapse(), expand(), change(), update(), click() or posistion() are defined for CollapseTree or TreeMap.

polling time sets chartRefresher.setRefreshInterval as polling time number * 1000 ms in createView(). It is only for bpm.


chart type

Define how the chart will be displayed, chart type is including

  • bar,
  • line,
  • pie,
  • donut,
  • bubble,
  • gauge and
  • tree

Syntax:

bar [shaded] [animated] [swapped] [stacked]
| line [animated] [showMarker] [trendline] [cursor [zoom] [tooltip]] [fillZero] [filled]
| pie [empty] 
| donut
| bubble [multiplier <value number>] [gradient | transparent]
| gauge [label <label value>] [hasTicks minimum <minValue number> maximum <maxValue number>][ intervals { up to <signed interval value> segmentcolor <rgb string>}]
| tree map|collapsible


Bar

Bar charts illustrate values as vertical or horizontal bars, respectively. Multiple data series, that is, two-dimensional data, are shown with thinner bars or columns grouped by their category.

Syntax:

bar [shaded] [animated] [swapped] [stacked]

Notes:

  • Inner axis is category axis and the outer axis is data axis.
  • shaded will be set with seriesDefaults.setShadow(true).setShadowAlpha(0.05f); in createChart().
  • animated will be set with options.setAnimate(true); in createChart().
  • swapped will be axisSwith which means YX instead of XY as axisPrefix..
  • stacked will be set with options.setStackSeries(true); in createChart().

Example:

chart SalesPerRegion described by "Sales per state/province" as bar shaded stacked swapped using datamart SalesByDistrict {
    axis rows renders category
    axis columns renders linear tickangle 25 
    legend inside toggle replot slow
    tooltip east always inside
}
