# Plot
|
|
|
|
[](https://travis-ci.org/tbreloff/Plot.jl)
|
|
|
|
Plotting interface and wrapper for several plotting packages.
|
|
|
|
First, clone the package, and get any plotting packages you need:
|
|
|
|
```
|
|
Pkg.clone("https://github.com/JuliaPlot/Plot.jl.git")
|
|
Pkg.clone("https://github.com/tbreloff/Qwt.jl.git") # requires pyqt and pyqwt
|
|
Pkg.add("Gadfly") # might also need to Pkg.checkout("Gadfly") and maybe Colors/Compose... I had trouble with it
|
|
```
|
|
|
|
Now load it in:
|
|
|
|
```
|
|
using Plot
|
|
```
|
|
|
|
Do a plot in Qwt, then save a png:
|
|
|
|
```
|
|
plotter(:Qwt)
|
|
plot(1:10)
|
|
savepng(ans, Plot.IMG_DIR * "qwt1.png")
|
|
```
|
|
|
|
which saves:
|
|
|
|
|
|
|
|
|
|
Do a plot in Gadfly, then save a png:
|
|
|
|
```
|
|
plotter(:Gadfly)
|
|
plot(1:10)
|
|
savepng(ans, Plot.IMG_DIR * "gadfly1.png", 6Gadfly.inch, 4Gadfly.inch)
|
|
```
|
|
|
|
which saves:
|
|
|
|
|
|
|
|
|
|
Note that you do not need all underlying packages to use this. I use Requires.jl to
|
|
perform lazy loading of the modules, so there's no initialization until you call `plotter()`.
|
|
This has an added benefit that you can call `using Plot` and it should return quickly...
|
|
no more waiting for a plotting package to load when you don't even use it. :)

julia> tic(); using Plot; toc();

|
|
|
|
julia> tic(); using Gadfly; toc();
|
|
WARNING: using Gadfly.Plot in module Main conflicts with an existing identifier.
