Bar Chart

Bar charts use horizontal tetragons to display information as bars. There are three types of bar chart, normal, stacked, and 100% stacked.

There are nine types of bar series available to create bar charts. Of these, the BarSeries, StackedBarSeries, and Stacked100PercentBarSeries are parent classes to two subclasses, one for date/time data and one of indexed data.

Normal

Normal bar charts create tetragons based on the data from a BarSeries. They use the DateTimeYAxis or IndexedYAxis as the y-axis (YAxis) and NumericXAxis as the x-axis (XAxis).

The following example uses an IndexedBarSeries to create a bar chart with indexed data.

// Create a PDF Document
Document document = new Document();
// Create a Page and add it to the document
Page page = new Page();
document.Pages.Add(page);

// Create a chart
Chart chart = new Chart(0, 0, 400, 230);
// Create a plot area
PlotArea plotArea = chart.PrimaryPlotArea;
// Create header titles and add it to the chart

Title title1 = new Title("Website Visitors");
Title title2 = new Title("Year 2007");
chart.HeaderTitles.Add(title1);
chart.HeaderTitles.Add(title2);

// Create a indexed bar series and add values to it
IndexedBarSeries barSeries1 = new IndexedBarSeries("Website A");
barSeries1.Values.Add(new float[] { 5, 7, 9, 6 });
IndexedBarSeries barSeries2 = new IndexedBarSeries("Website B");
barSeries2.Values.Add(new float[] { 4, 2, 5, 8 });
IndexedBarSeries barSeries3 = new IndexedBarSeries("Website C");
barSeries3.Values.Add(new float[] { 2, 4, 6, 9 });

// Create autogradient and assign it to series
AutoGradient autogradient1 = new AutoGradient(180f, CmykColor.Red, CmykColor.IndianRed);
barSeries1.Color = autogradient1;
AutoGradient autogradient2 = new AutoGradient(180f, CmykColor.Green, CmykColor.YellowGreen);
barSeries2.Color = autogradient2;
AutoGradient autogradient3 = new AutoGradient(180f, CmykColor.Blue, CmykColor.LightBlue);
barSeries3.Color = autogradient3;

// Add indexed bar series to the plot area
plotArea.Series.Add(barSeries1);
plotArea.Series.Add(barSeries2);
plotArea.Series.Add(barSeries3);

// Create a title and add it to the xaxis
Title lTitle = new Title("Visitors (in millions)");
barSeries1.XAxis.Titles.Add(lTitle);

//Adding AxisLabels to the yAxis
barSeries1.YAxis.Labels.Add(new IndexedYAxisLabel("Q1", 0));
barSeries1.YAxis.Labels.Add(new IndexedYAxisLabel("Q2", 1));
barSeries1.YAxis.Labels.Add(new IndexedYAxisLabel("Q3", 2));
barSeries1.YAxis.Labels.Add(new IndexedYAxisLabel("Q4", 3));

Stacked

Stacked charts display related data, one on top of the other. They use DateTimeYAxis or IndexedYAxis as the y-axis (YAxis) based on the series and NumericXAxis as the x-axis (XAxis).

The following example uses an IndexedStackSeries to create a bar chart based on indexed data.

// Create a PDF Document
Document document = new Document();
// Create a Page and add it to the document
Page page = new Page();
document.Pages.Add(page);

// Create a chart
Chart chart = new Chart(0, 0, 400, 230);

PlotArea plotArea = chart.PrimaryPlotArea;

// Create header titles and add it to the chart
Title title1 = new Title("Website Visitors");
Title title2 = new Title("Year 2007");
chart.HeaderTitles.Add(title1);
chart.HeaderTitles.Add(title2);

// Create a indexed stacked bar series elements and add values to it

100% Stacked

100% stacked charts are similar to stacked charts, but the data is expressed as a percentage. These charts use DateTimeYAxis or IndexedYAxis as the y-axis (YAxis) based on the series and PercentageXAxis as the x-axis (XAxis).

The following example uses an Indexed100PercentStackedBarSeries to create a bar chart based on percentage indexed data.

// Create a PDF Document
Document document = new Document();
// Create a Page and add it to the document
Page page = new Page();
document.Pages.Add(page);

// Create a chart
Chart chart = new Chart(0, 0, 400, 230);
// Create a plot area
PlotArea plotArea = chart.PrimaryPlotArea;

// Create header titles and add it to the chart
Title title1 = new Title("Website Visitors");
Title title2 = new Title("Year 2007");
chart.HeaderTitles.Add(title1);
chart.HeaderTitles.Add(title2);

// Create a indexed 100% bar series elements and add values to it
Indexed100PercentStackedBarSeriesElement seriesElement1 = new Indexed100PercentStackedBarSeriesElement("Website A");
seriesElement1.Values.Add(new float[] { 5, 7, 9, 6 });
Indexed100PercentStackedBarSeriesElement seriesElement2 = new Indexed100PercentStackedBarSeriesElement("Website B");
seriesElement2.Values.Add(new float[] { 4, 2, 5, 8 });
Indexed100PercentStackedBarSeriesElement seriesElement3 = new Indexed100PercentStackedBarSeriesElement("Website C");
seriesElement3.Values.Add(new float[] { 2, 4, 6, 9 });

// Create autogradient and assign it to series
AutoGradient autogradient1 = new AutoGradient(180f, CmykColor.Red, CmykColor.IndianRed);
seriesElement1.Color = autogradient1;
AutoGradient autogradient2 = new AutoGradient(180f, CmykColor.Green, CmykColor.YellowGreen);
seriesElement2.Color = autogradient2;
AutoGradient autogradient3 = new AutoGradient(180f, CmykColor.Blue, CmykColor.LightBlue);
seriesElement3.Color = autogradient3;

// Create a Indexed 100% Stacked Bar Series
Indexed100PercentStackedBarSeries barSeries = new Indexed100PercentStackedBarSeries();
// Add SeriesElements to the Indexed 100% Stacked Bar Series
barSeries.Add(seriesElement1);
barSeries.Add(seriesElement2);
barSeries.Add(seriesElement3);
// Add series to the plot area
plotArea.Series.Add(barSeries);

// Create a title and add it to the xaxis
Title lTitle = new Title("Visitors (in millions)");
barSeries.XAxis.Titles.Add(lTitle);

//Adding AxisLabels to the yaxis
barSeries.YAxis.Labels.Add(new IndexedYAxisLabel("Q1", 0));
barSeries.YAxis.Labels.Add(new IndexedYAxisLabel("Q2", 1));
barSeries.YAxis.Labels.Add(new IndexedYAxisLabel("Q3", 2));
