Hello,

I am trying to use Weave.jl with PyPlot for plotting (on v0.7), but I am not getting any plot in the PDF or HTML document. Did someone was successful to use Weave with PyPlot? (For the moment, I am just trying to make the example julia\_sample.mdw work, from Weave)

Thank you.

Can you post an [MWE](https://discourse.julialang.org/t/psa-make-it-easier-to-help-you/14757) so that people can try out what you’re doing and see whether it might be due to e.g. some issue with your PyPlot installation?

So I finally fixed my problem, thank you. I tried to to follow the example in the Weave package but it was not working. My original code looked as the following ():

```julia
## Capturing figures
The figures and code can be included in the output.

<<term=false;echo=false>>=
using PyPlot
PyPlot.close()
x = [1:1:50;];
y = 10*rand(50);
fig = figure("pyplot_barplot",figsize=(5,5))
b = bar(x,y,color="#0f87bf",align="center",alpha=0.9)
axis("tight")
title("Vertical Bar Plot")
grid(true)
xlabel("X")
ylabel("Y")
@

```

And when I was using weave  
`weave(joinpath(dirname(pathof(Weave)), "../examples", "julia_example.mdw"),out_path=:pwd, doctype="md2html")`  
The plot was not included in the html (same thing with ‘md2pdf’).  
I finally add `display(fig);` and it finally worked.

```julia
## Capturing figures
The figures and code can be included in the output.

<<term=false;echo=false>>=
using PyPlot
PyPlot.close()
x = [1:1:50;];
y = 10*rand(50);
fig = figure("pyplot_barplot",figsize=(5,5))
b = bar(x,y,color="#0f87bf",align="center",alpha=0.9)
axis("tight")
title("Vertical Bar Plot")
grid(true)
xlabel("X")
ylabel("Y")
display(fig);
@

```

I’m a new comer here. I ran the julia\_example.mdw in julia-1.0.1 with the same problem with “ERROR: UndefVarError: linspace not defined”.

But I had just read the earlier posting " [UndefVarError: linspace not defined](https://discourse.julialang.org/t/undefvarerror-linspace-not-defined/13269).

We need to add Weave.jl to their list of deprecated ‘linspace’ usages in the julia space.

🙂

HI Gary,

My personal advice is to use julia-v0.7 for the moment. Some useful packages are not yet up to date with Julia-v1, the advantage of julia-v0.7 is it will output a warning message instead of error message and it will indicate what is deprecated and what is now recommended.  
I think that the examples in Weave.jl are outdated. Therefore, it is really time consuming to figure it out how it should work.
