How to plot a ‘percentage plot’ with ggplot2 – Sebastian …

At times it is convenient to draw a frequency bar plot; at times we prefer not the bare frequencies but the proportions or the percentages per category. There are lots of ways doing so; let’s look at some ggplot2 ways. First, let’s load some data.

Histograms and frequency polygons — geom_freqpoly • …

geom_bar(). This method by default plots tick marks in between each bar. Orientation This geom treats each axis differently and, thus, can thus have two orientations. Often the orientation is easy to deduce from a combination of the given mappings and

Dodge overlapping objects side-to-side — …

Dodging preserves the vertical position of an geom while adjusting the horizontal position. position_dodge() requires the grouping variable to be be specified in the global or geom_* layer. Unlike position_dodge(), position_dodge2() works without a grouping variable in a layer. position_dodge2() works with bars and rectangles, but is particulary useful for arranging box plots, which can have

Stack overlapping objects on top of each another — …

Details position_fill() and position_stack() automatically stack values in reverse order of the group aesthetic, which for bar charts is usually defined by the fill aesthetic (the default group aesthetic is formed by the combination of all discrete aesthetics except for x and y).

“看看我吧,就把該參數設定為 NULL 即可,也就是做頻數圖。 但是,並配合 aes() 函數指定散佈圖的資料來源,高度表示的含義是由geom_bar()函數的參數stat決定的,可以同時映射x,其效果只會影響該圖層本身, https://goo.gl/W4p3VJ 讓我們開始吧,

The geom_bar and geom_col layers are used to create bar charts. With the first option, you need to specify stat = “identity” for it to work, so the ladder is used throughout the article. You can create a simple bar chart with this code:

R
geom_bar() makes the height of the bar proportional to the number of cases in each group (or if the weight aesthetic is supplied, the sum of the weights). If you want the heights of the bars to represent values in the data, use geom_col() instead.
