Graphs or Charts DSL allows to quickly draw charts. The most complex part is transforming the source data to dataset accepted by the API.

Code Sample

Figure 1. Barchart Graph.
Graph Sample for Barcharts
        Set<String> dates = []
        Set<String> origins = []
        Map<String, List<BigDecimal>> totalPerOrigin = [:]
        rowResults.each {
            String d = it['date_part'].toString()
            String o = it['origin'].toString()
            dates << d
            origins << o
            if (!totalPerOrigin[o]) totalPerOrigin[o] = []
            totalPerOrigin[o] << new BigDecimal(it['total_price']?.toString() ?: "0.0").round(0)
        }

        UiChartSpecifier chart = new UiChartSpecifier() (1)
        chart.ui {
            barChart(dates.sort(), { (2)
                origins.sort().eachWithIndex { o, i ->
                    dataset o, ChartDatasetSpec.Color.values()[i], totalPerOrigin[o] (3)
                }
            })
        }

  1. Create the charts description and call ui method

  2. Add one barChart with dates label

  3. create dataset for each origin
