Line charts

A line chart plots a series of data points on a graph and connects them with lines. A line chart is useful for showing trend lines with subtle differences, or with data lines that cross one another. You can use a line chart to summarize categorical variables, in which case it is similar to a bar chart (see Bar charts ). Line charts are also useful for time-series data.

Creating a simple time-series line chart

In the Chart Type section, click the Line icon.
The canvas updates to display a line chart template.
Select a date variable as the X-axis variable.
Select a scale variable as the Y-axis variable (the variable whose values were recorded over time).
Click the Save visualization in the project control. Select Create a new asset or Append to existing asset. Provide a Visualization asset name, an optional description, and a chart name.
Click Apply to save the visualization to the project. The new visualization asset is now available on the Assets tab.

Options

X-axis

Lists variables that are available for the chart's X-axis.

Y-axis

Lists variables that are available for the chart's Y-axis.

Split by

Select a categorical variable that creates a table of charts, with a cell for each category in the Split by variable. Like grouping, split by variables essentially add more dimensions to your chart by displaying information for each variable category.

Area

When enabled, the area beneath the line is shown in a different color.

Smooth

When enabled, the chart shows a smooth curve.

Show data points

When enabled, the data point is shown in the chart.

Reorder

The toggle control reorders data based on X and Y-axis values.

Fit line

In a fit line, the data points are fitted to a line that usually does not pass through all of the data points. The fit line represents the trend of the data. Some fits lines are regression-based. Others are based on iterative weighted least squares. Select a fit line option from the drop-down list.

Show reference line

When enabled, the option shows a reference line on the chart that is based on the specified xAxis and yAxis values.

Enter a reference line value on xAxis: When Show reference line is enabled, this setting provides the option of specifying a specific reference line value for the X-axis. Click Add another column to specify more reference line values.
Enter a reference line value on yAxis: When Show reference line is enabled, this setting provides the option of specifying a specific reference line value for the Y-axis. Click Add another column to specify more reference line values.
