We can plot in Julia using various packages like pyplot
, plotly
, and so on. Plots.jl
is one such package using which we can plot in Julia.
Plots.jl
can be installed using the following commands:
import Pkg;
Pkg.add("Plots")
The first command imports the package manager. The second command downloads and installs the package.
To use the package, execute the following command:
using Plots
In Julia, a bar graph is created using the bar()
function of the Plots
package:
using Plots
bar(x, y)
x
: These are the data points along the x
dimension.y
: These are the data points along the y
dimension.using Plotsx = [1,2,3]y = [4,5,6]bar(x,y)savefig("output/plot.png")
Plots
package.bar()

.We can create a histogram in Julia using the histogram()
function of the Plots
package.
using Plots
histogram(x, nbins, weights, normalize)
x
: These are the data points to be plotted.nbins
: This is an integer or vector that defines the number of bins to place the input data points.weights
: This is a vector that defines the weights for the data points.normalize
: This is a boolean value indicating whether or not to normalize the data points. The default value is false
. This denotes that no normalization is performed.using Plotsdata = randn(1000)histogram(data, nbins=20)savefig("output/plot.png")
Plots
package.histogram()
function, where the number of bins is set to 20
