    InsightJS Travis Results

    InsightJS is a JavaScript data aggregation and visualization library that allows you to quickly load and find patterns in datasets. Given a data set, InsightJS can group the records across the dimensions of the data to quickly aggregate and provide statistics on the data.

    Version 1.4.0 (08-Jan-2015)

    • Library changes:

      • Added grouping to Simple Chart builders
      • Added parameter to insight.Legend constructor to allow a chosen series to be omitted from the legend
      • Added Series title truncation in insight.Legend
    • Issues fixed:

      • Fixed bug where Legend is cut off if a series title is too long

    Version 1.3.0 (18-Nov-2014)

    • Library changes:
      • Charts can now be styled using CSS
      • Added Simple Chart builders that produce charts with default configurations

    Version 1.2.1 (04-Nov-2014)

    • Library changes:
      • Improved documentation for working with groupings.
      • Updated Grouping calculations to improve consistency
        • Grouping.count() stores total count in value.propertyName.totalCount rather than value.propertyName.Total
        • Grouping.mean() stores mean in value.propertyName.mean rather than value.propertyName.Average
        • Grouping.sum() stores sum in value.propertyName.sum rather than value.propertyName.Sum
      • Removed insight.Chart.title
      • Added insight.Series.title
      • Updated library to work with crossfilter to 1.3.11
      • Added utility, insight.conversion, for converting arff data to json data

    Issues fixed:

    • insight.DataSet.group function ignored any filter already applied on the DataSet.

    Version 1.2.0 (07-Oct-2014)

    • Library changes:

      • Added Chart.titlePadding, to configure the distance between the chart title and plot area.
      • Added Axis.tickWidth and Axis.tickColor to configure the appearance of axis tick marks. Defaults are taken from the Theme.axisStyle.tickLineColor and Theme.axis.tickLineWidth respectively.
      • Added BarSeries as a common base class between RowSeries and ColumnSeries. BarSeries should not be initialized directly, but contains methods used in both RowSeries and ColumnSeries.
      • Added manual axis domains. Use Axis.axisRange(min, max) to set the axis range to a custom range.
      • Renaming
        • insight.Axis.axisLabelColor => insight.Axis.axisTitleColor
        • insight.Axis.axisLabelFont => insight.Axis.axisTitleFont
        • insight.Axis.label => insight.Axis.title
        • insight.Theme.axisStyle.showGridlines => insight.Theme.axisStyle.shouldShowGridlines
        • insight.Theme.axisStyle.axisLabelFont => insight.Theme.axisStyle.axisTitleFont
        • insight.Theme.axisStyle.axisLabelColor => insight.Theme.axisStyle.axisTitleColor
        • insight.Theme.seriesStyle.showPoints => insight.Theme.seriesStyle.shouldShowPoints
        • insight.Formatters => insight.formatters.
        • insight.Scales.Linear => insight.scales.linear
        • insight.Scales.Ordinal => insight.scales.ordinal
        • insight.Scales.Time => insight.scales.time
        • insight.Constants => insight.constants
        • insight.Utils => insight.utils
        • insight.correlation.fromDataSet => insight.correlation.fromDataProvider
    • Issues fixed:

      • Date axis tick labels were jumping on interactive charts
      • Charts were not able to be drawn with no data

    Getting Started

    Using InsightJS requires the following libraries:

    InsightJS is also compatible with RequireJS.

    Include the required libraries and InsightJS.

    Load a dataset and start analyzing and creating charts!

    <script type="text/javascript" src="//cdnjs.cloudflare.com/ajax/libs/insightjs/1.2.0/insight.min.js"></script>
    d3.json('appstore.json', function(data)
        var dataset = new insight.DataSet(data);
        var genreGroup = dataset.group('genre', function(d)
            return d.primaryGenreName;
        var chart = new insight.Chart('AppGenres', '#chart')
        var x = new insight.Axis('Genre', insight.scales.ordinal)
        var y = new insight.Axis('No. Apps', insight.scales.linear);
        var columns = new insight.ColumnSeries('columns', genreGroup , x, y)
                                        return d.value.Count;
