Error bars

To visualize error bars on points, you can use the error property of data entries for point plots. The error can be a single number (a constant error for all data points). By specifying an array of numbers instead, you can assign individual error bars for each data point.

If the positive error and the negative error are not symmetrical, you can use upperError and/or lowerError. Similar to the error property, you can specify a constant or an array.
