Some attributes have their own dedicated modifier functions, while others can be accessed through plot!(attribute=value). Plot(x,, title='Trigonometric functions', label=, linewidth=3)Įvery attribute can also be applied by mutating the plot with a modifier function. Let's apply all of this to our previous plot: x = range(0, 10, length=100) Additionally, since the line width is being attributed to, both lines will be affected by the assigned value. Notice how has the same number of columns as the data. So something like plot(x, y, z) is three-dimensional data for 3D plots with no attributes, while plot(x, y, attribute=value) is two-dimensional data with one attribute assigned to some value.Īs an example, we can change the line width using linewidth (or its alias lw), change the legend's labels using label, and add a title with title.

Keyword arguments correspond to attributes.

Positional arguments correspond to input data.

Plots.jl follows two simple rules with data and attributes: In Plots.jl, the modifiers to plots are called attributes, which are documented at the attributes page. we're done, right? No! We need to style our plots. More information about outputting figures can be found in the Output section of the Manual. The following is equivalent to the above code: png('myplot') With these, the extension is omitted from the filename. There also exist convenience functions png, Plots.pdf and other unexported helpers. Savefig(p, 'myplot.pdf') # saves the plot from p as a. For example: savefig('myplot.png') # saves the CURRENT_PLOT as a. Saving plots is done by the savefig command. In cases where the plot variable is omitted, Plots.jl uses the global Plots.CURRENT_PLOT automatically. Note that we could have done the same as above using an explicit plot variable, which we call p: x = range(0, 10, length=100)

If we inputted the dots manually, we would need three of them for the sine, exponent, and subtraction, and the resulting code would be less readable. This is a convenience macro that inserts dots for every function call to the right of the macro, ensuring that the entire expression is to be evaluated in an element-wise manner. This is done by the plot! command, where the ! denotes that the command is modifying the current plot.

x = range(0, 10, length=100)Īdditionally, we can add more lines by mutating the plot object. Below, forms a 100x2 matrix (100 elements, 2 columns). We can plot multiple lines by plotting a matrix of values where each column is interpreted as a separate line. In Plots.jl, every column is a series, a set of related points which form lines, surfaces, or other plotting primitives. Because of the way Julia works under the hood, this is a difficult problem to solve, but much progress has been made in the past few years to reduce this compilation time. If this is your first plot of the session and it takes a while to show up, this is normal this latency is called the 'time to first plot' problem (or TTFP), and subsequent plots will be fast. The plot is displayed in a plot pane, a stand-alone window or the browser, depending on the environment and backend (see below). To do this in Julia, we insert a dot right after the function call. For the y coordinates, we can create a vector by evaluating sin(x) in an element-wise fashion. For the x coordinates, we can create a range from 0 to 10 of, say, 100 elements. To start, let's plot some trigonometric functions. Depending on your computer, this will take a few seconds: using Plots Basic Plotting: Line PlotsĪfter you have installed Plots.jl via Pkg.add('Plots'), the first step is to initialize the package. It is recommended that the code examples be followed inside the REPL or an interactive notebook.

Its main goal is to introduce you to the terminology used in the package, how to use Plots.jl in common use cases, and put you in a position to easily understand the rest of the manual.

This is a guide for getting you up and running with Plots.jl.
