If you really got stuck with plotting using native Julia, as a last resort, you can also use MATLAB to plot directly from Julia using `MATLAB.jl`

.

```
using MATLAB
mxcall(:subplot,0, "111")
mxcall(:pcolor, 0, con)
mxcall(:shading,0,"interp")
mxcall(:axis,0,"off")
mxcall(:axis,0,"equal")
mxcall(:title,0,"simulation")
mxcall(:colorbar,0)
temp="fig$(jj).png"
@mput temp
mat"saveas(gca,temp)"
```

So basically, `con`

is a julia `Array{Float64,2}`

it can be used as julia type directly, and `temp`

is String, but it need to put into MATLAB session, because Julia canāt hold the gca type, so `saveas(gca,temp)`

has to be eval inside MATLAB as an expression.

or just put the data you want to plot into MATLAB session and eval the whole script:

```
using MATLAB
temp="fig$(jj).png"
@mput con
@mput temp
mat"""
subplot(1,1,1)
pcolor(con), shading interp, ...
axis('off'), axis('equal'), title('simulation');
colorbar
saveas(gca,temp);
"""
```
