Creating Line charts

A Line chart is a type of chart which displays information as a series of data points called 'markers' connected by straight line segments.

Data can be presented in different ways in a Line chart - as lines, area, or stacked area, when you have more than one measure. The Line chart is easy to understand and provides an instant perception of trends.

When to use a Line chart

The Line chart is particularly useful when you want to visualize trends and movements over time, where the dimension values are evenly spaced, such as months, quarters, or fiscal years.

More than a few lines in a Line chart makes it cluttered and hard to interpret. For this reason, it is recommended to create a Line chart using not more than two or three measures.

Creating line charts

1.   On the toolbar, select + New Page from the Pages drop down, or on the Filters and Settings pane, select the Pages tabbed page and then click the + icon to create a new page.

2.   Click the icon in the chart area and then select the Basic tabbed page.

3.   Select the Line chart type or click theicon at the top right corner of the chart area and then select Line to create a Line chart.

4.   From the Dimensions pane, specify an X Axis Dimension for the Line chart.

5.   Specify a Measure for your chart.

Optionally, specify a Legend Dimension for your chart.

6.   In the Filters and Settings pane, select any of the following:

▪       Filters tabbed page to browse the chart dimensions using the Dimensions Browser.

▪       Pages to view all pages in the current report as thumbnails.

▪       Settings to define drill through, page, or report properties for the chart.

• Before creating a visualization, it is recommended to select the Dimension Browser view by selecting the Filters tabbed page from the Filters and Settings pane. The Dimensions Browser enables you to easily drag and drop Dimensions or Measures from the Dimensions pane (depending on the chart type) into Dimensions, Measures, Legend, or Browsing Dimensions of the Dimension Browser.
