geom
Dotplot represents individual observations in a batch of data with circular dots. The diameter of a dot corresponds to the maximum width or bin width, depending on the binning algorithm.
Notes
With "dotdensity" binning, the bin positions are determined by the data and binwidth, which is the maximum width of each bin. With "histodot" binning, the bins have fixed positions and fixed widths, much like a histogram.
Computed variables:
..count.. : number of points with x-axis coordinate in the same bin.
..binwidth.. : max width of each bin if method is "dotdensity"; width of each bin if method is "histodot".
To hide axis tooltips, set "blank" or the result of elementBlank() to the axisTooltip or axisTooltipX parameter of the theme().
Examples
Parameters
The data to be displayed in this layer. If null, the default, the data is inherited from the plot data as specified in the call to letsPlot.
default = true. false - do not show legend for this layer.
default = true. false - do not combine the layer aesthetic mappings with the plot shared mappings.
String or result of the call to the layerKey() function. The key to show in the manual legend. Specifies the text for the legend label or advanced settings using the layerKey() function.
Result of the call to the samplingXxx() function. To prevent any sampling for this layer pass value samplingNone. For more info see sampling.html.
Result of the call to the layerTooltips() function. Specifies appearance, style and content. Set tooltips = tooltipsNone to hide tooltips from the layer.
X-axis coordinates.
When method is "histodot", this specifies number of bins (default = 30). Overridden by binWidth.
When method is "histodot", this specifies x-value to align bin centers to.
When method is "histodot", this specifies x-value to align bin boundary (i.e. point between bins) to.
default = "dotdensity". Use "dotdensity" for dot-density binning, or "histodot" for fixed bin widths (like in geomHistogram).
When method is "dotdensity", this specifies maximum bin width. When method is "histodot", this specifies bin width.
Which direction to stack the dots. Values: "up", "down", "center", "centerwhole" (default = "up").
default = 1.0. How close to stack the dots. Use smaller values for closer, overlapping dots.
default = 1.0. The diameter of the dots relative to binWidth.
Stack dots across groups when method = "histodot".
Width of the dot border.
Transparency level of a layer. Understands numbers between 0 and 1.
Color of geometry lines. For more info see: aesthetics.html#color-and-fill.
Fill color. For more info see: aesthetics.html#color-and-fill.
default = "color" ("fill", "color", "paint_a", "paint_b", "paint_c"). Defines the color aesthetic for the geometry.
default = "fill" ("fill", "color", "paint_a", "paint_b", "paint_c"). Defines the fill aesthetic for the geometry.
Set of aesthetic mappings. Aesthetic mappings describe the way that variables in the data are mapped to plot "aesthetics".
