Line Chart Formatting

Line charts have different options to control styling behavior. Options are arguments passed to a given series in the chart function.

• Use color to control the color of the series. The color names match options from Ernie and our YD style guide.

• By default the series mode is set to lines for a line chart

• The shape argument can control the line shape. The options are dash for long dashes, dot for short dashes, or spline for smooth curve lines.

• The mode argument can also be set to markers for plotting only data points and lines+markers to display both lines and markers at the data point.

• By default, line charts are solid lines with no markers or smoothing.
