In the process of drawing, sometimes we may need to add some lines, so that the visualization of the graph becomes better, such as some trend lines and so on.Let's take a look at some of the ways the lines are added.Geom_abline (mapping = NULL, data = NULL, ..., slope, intercept, na.rm = FALSE, show.legend = NA) geom_hline (mapping = NULL, data = null, ..., yintercept, na.rm = FALSE, show.legend = NA) geom_vline (mapping = NULL, data = NULL, ..., xintercept, NA .

Facets can be compared by placing different subclasses in different graphs:Qplot (carat, data = diamonds, facets = Color ~., Geom = "Histogram", Binwidth = 0.1, Xlim = C (0, 3))Qplot (carat, data = diamonds, facets = Color ~., Geom = "Histogram", Binwidth = 0.1, Xlim = C (0, 3))The following graphic adds new elements based on the beginning: faceted, multiple layers, and statistics. Facets and layers extend the data structures mentioned above: each layer of each facet has its own datase

Related attribute scale settingIncludes Scale_size (), Scale_alpha (), Scale_shape ()As you can see from the name above, these three settings are primarily related to the Ggplot layer properties, including size, transparency, and shape.The main parameters for this setting are listed below:SCALE_XXX (name = Waiver (), breaks = waiver (),

Introduction A line chart is generally used to describe a variable of one-dimensional variables as a continuous variable, which is usually time. In other words, a line chart is best suited to describe changes in time series data. Of course, with the change of discrete variables is also possible, but this discrete variable must be ordered. Draw a line chart A basic line chart is relatively simple, as long as the AES in the Ggplot x,y data and Geom designated as line. If x is a continuous variable

In my opinion, the algorithm and the data structure are like the methodology and epistemology in philosophy, the former clarifies the idea of solving a problem, and the latter provides the object of solving the problem.The term "algorithm" d
