A Plot is only displayed when returned (a semicolon will suppress the return), or if explicitly displayed with
gui(), or by adding
show = true to your plot command.
!!! tip You can have MATLAB-like interactive behavior by setting the default value: default(show = true)
gui(plt) will open a standalone window.
plot!(...), applies to the "current" Plot. Returning a Plot object to the REPL is like calling
Jupyter / IJulia
Plots are shown inline when returned to a cell. The default output format is
svg for backends that support it.
This can be changed by the
html_output_format attribute, with alias
plot(rand(10), fmt = :png)
Juno / Atom
Plots are shown in the Atom PlotPane when possible, either when returned to the console or to an inline code block. At any time, the plot can be opened in a standalone window using the
The PlotPane can be disabled in Juno's settings.
savefig / format
Plots support 2 different versions per save-command.
savefig chooses file type automatically based on the file extension.
savefig(fn) # save the most recent fig as fn savefig(plot_ref, fn) # save the fig referenced by plot_ref as fn
In addition, Plots offers shorthands like
In this case the string fn containing the filename does not need a file extension.
png(fn) # save the current fig as png with filename fn png(plot_ref, fn) # save the fig referenced by plot_ref as png with filename fn
File formats supported by most graphical backends
- png (default output format for
savefig, if no file extension is given)
When not using
savefig, the default output format depends on the environment (e.g., when using IJulia/Jupyter).
Supported output file formats
Note: not all backends support every output file format ! A simple table showing which format is supported by which backend
