The following doesn’t produce any output using Juno and v0.6 of Julia:

```
histogram(randn(10))
for i = 1:10
histogram!(randn(10))
end
```

why is that?

Don’t you need to add TO an existing plot?

```
p = histogram(randn(10))
for i in 1:10
histogram!(p, randn(10))
end
p
```

yields

GR:

```
using GR
inline("atom")
for i in 1:100
histogram(randn(10000))
end
```

Plots + gr():

```
using Plots
gr()
for i in 1:100
display(histogram(randn(10000)))
end
```

If you plot from within a loop using Plots, I believe you have to call the function `gui()`

in the end of the loop for the results to be displayed.

If you add to a plot within a loop, no plot object is returned and thus nothing is shown. Another alternative to the above advices is returning the current plot object with `current()`

after the loop:

```
histogram(randn(10))
for i in 1:10
histogram!(randn(10))
end
current()
```

maybe this discussion helps:

This do help! I applied it to plot from within two nested for loop in a function.

```
function bala()
for i
for j
if
plot ()
else
plot!()
end
end
end
return current() #return the plot!!!!
end
```

so I can do

p1=func() #this allow it to be used as subplot

Thank you!

You can also try calling `display()`

on the output of the plot within the loop. That’s what I’ve been doing.
