About Charts

The layout editor supports a variety of chart types and styles to graphically present data in the layout.

After you insert a chart, you can edit the chart properties using the dynamic toolbars or the Properties pane. The Properties pane extends the options from the Chart tab and enables you to enter very specific custom settings for the following:

  • Chart Effect

  • Chart Legend

  • Chart Plot Area

  • Chart Title

  • Chart Label

  • Chart Values

The following Chart Label properties apply to Scatter and Bubble chart types only: Title Font, Title Horizontal Align, Title Text, and Title Visible.

Some font effects such as underline, italic, and bold might not render in PDF output.

The text size for legends, title, and numerical values in Bar charts might be decreased in a PDF output when compared with an interactive output, because the size of the PDF page is lesser than the size of the HTML browser page used for the interactive output.

Insert a Chart

To insert a chart:
  1. From the Insert menu, select and drag the Chart component to the layout.
