Line chart
Display quantitative values over a continuous interval or time period by creating a line chart.
Details
Create a line chart by selecting a continuous interval or time period variable (x) along with a continuous variable (y). Add a categorical grouping value which will split and colour the lines accordingly. Customise your plot further by selecting the line type, alpha (opacity) and whether the data points should be visible.
