A bar plot or bar chart is a graph that represents the category of data with rectangular bars with lengths and heights that is proportional to the values which they represent.
Mat plot lib bar chart 2 y axis.
The bar plots can be plotted horizontally or vertically.
Each of x height width and bottom may either be a scalar applying to all bars or it may be a sequence of length n providing a separate value for each bar.
The optional parameter fmt is a convenient way for defining basic formatting like color marker and linestyle.
For example suppose y represents depth of the ocean in m.
The existing plots and the left y axis do not change colors.
New plots added to the axes use the same color as the corresponding y axis.

The vertical baseline is bottom default 0.
And the values as the y axis.
The right y axis uses the next color in the axes color order.
You can create all kinds of variations that change in color position orientation and much more.
Their dimensions are given by height and width.
The bars are positioned at x with the given alignment.
Add a second y axis to an existing chart using yyaxis.
The bars are positioned at x with the given alignment.
The y axis limits might be set like the following so 5000 m depth is at the bottom of the plot and the surface 0 m is at the top.
It s a shortcut string notation described in the notes section below.
The bars will have a thickness of 0 25 units.
The data variable contains three series of four values.
Matplotlib is a python module that lets you plot all kinds of charts.
The following script will show three bar charts of four bars.
Limits may be passed in reverse order to flip the direction of the y axis.
Bar charts is one of the type of charts it can be plot.
We can plot multiple bar charts by playing with the thickness and the positions of the bars.
The coordinates of the points or line nodes are given by x y.
Bar chart on polar axis.
Each bar chart will be shifted 0 25 units from the previous one.
A bar chart describes the comparisons between the discrete categories.
If you ve worked through any introductory matplotlib tutorial you ve probably called something like plt plot 1 2 3 this one liner hides the fact that a plot is really a hierarchy of nested python objects.
