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).

Indexed

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

1. Create three IndexedBarSeries instances and add values to each.
2. Add the series to the plot area.
3. Add y-axis labels to each of the series (IndexedYAxisLabel).
4. Add the chart to the page and produce the PDF.

// 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));

Date/Time

The following example illustrates a normal bar chart using date/time data. Perform the following steps to create the chart.

1. Create three DateTimeBarSeries instances and add values.
2. Add the series to the plot area.

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).

Indexed

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

1. Create the IndexedStackedBarSeries instance.
2. Create three IndexedStackedBarSeriesElement and add values to each.
3. Add the elements to the series.
4. Add the series to the plot area.
5. Add the y-axis labels (IndexedYAxisLabel).
6. Add the chart to the page and create the PDF.

// 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

// 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
IndexedStackedBarSeries barSeries = new IndexedStackedBarSeries();

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

seriesElement1.Values.Add(new float[] { 5, 7, 9, 6 });
IndexedStackedBarSeriesElement seriesElement2 = new IndexedStackedBarSeriesElement("Website B");
seriesElement2.Values.Add(new float[] { 4, 2, 5, 8 });
IndexedStackedBarSeriesElement seriesElement3 = new IndexedStackedBarSeriesElement("Website C");
seriesElement3.Values.Add(new float[] { 2, 4, 6, 9 });

// Create autogradient and assign it to series

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).

Indexed

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

1. Create a Indexed100PercentStackedBarSeries instance.
2. Create three Indexed100PercentStackedBarSeriesElement instances and add values to each.
3. Add the elements to the series.
4. Add the x-axis title and the y-axis labels (IndexedYAxisLabel).
5. Add the series to the plot area.
6. Add the chart to the page and produce the PDF.

// Create a PDF Document

// Create a Page and add it to the document

Date/Time

The following example illustrates a 100% stacked bar chart with date/time data. Perform the following steps to produce the chart.

1. Create a DateTime100PercentStackedBarSeries instance.
2. Create three DateTime100PercentStackedBarSeriesElement instances and add elements to each.
3. Add the elements to the series and the series to the plot area.
4. Add the x-axis title and the y-axis date/time label format.
5. Add the chart to the page and produce the PDF.

// 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, 200);

// Get the default plot area from the chart
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 date time 100 percent stacked bar series
DateTime100PercentStackedBarSeries stackedBarSeries1 = new DateTime100PercentStackedBarSeries();

// Create a date time 100 percent stacked bar series element and add values to it
DateTime100PercentStackedBarSeriesElement seriesElement1 = new DateTime100PercentStackedBarSeriesElement("Website A");
seriesElement1.Values.Add(5, new DateTime(2007, 1, 1));
seriesElement1.Values.Add(7, new DateTime(2007, 2, 1));
seriesElement1.Values.Add(9, new DateTime(2007, 3, 1));
seriesElement1.Values.Add(6, new DateTime(2007, 4, 1));
DateTime100PercentStackedBarSeriesElement seriesElement2 = new DateTime100PercentStackedBarSeriesElement("Website B");
seriesElement2.Values.Add(4, new DateTime(2007, 1, 1));
seriesElement2.Values.Add(2, new DateTime(2007, 2, 1));
seriesElement2.Values.Add(5, new DateTime(2007, 3, 1));
seriesElement2.Values.Add(8, new DateTime(2007, 4, 1));
DateTime100PercentStackedBarSeriesElement seriesElement3 = new DateTime100PercentStackedBarSeriesElement("Website C");
seriesElement3.Values.Add(2, new DateTime(2007, 1, 1));
seriesElement3.Values.Add(4, new DateTime(2007, 2, 1));
seriesElement3.Values.Add(6, new DateTime(2007, 3, 1));
seriesElement3.Values.Add(9, new DateTime(2007, 4, 1));

//add date time 100 percent stacked bar series elements to it
stackedBarSeries1.Add(seriesElement1);
stackedBarSeries1.Add(seriesElement2);
stackedBarSeries1.Add(seriesElement3);

// Add date time stacked bar series to the plot area
plotArea.Series.Add(stackedBarSeries1);

// Create a title and add it to the XAxis
Title title3 = new Title("Viewers");
stackedBarSeries1.XAxis.Titles.Add(title3);

// Set label  format to the axis labels
stackedBarSeries1.YAxis.LabelFormat = "MMM";

// Add the chart to the page
page.Elements.Add(chart);

// Save the PDF
document.Draw(outputPath);
