# using sage functions with data from octave

Hello, I´m trying to construct a histogram using octave within sage, but I don´t know how to use sage functions with data that comes from octave, here´s what I´m doing:

```
a = octave.normrnd(50,3,100,1) #this generates a column vector with normal random data
b = octave.hist(a) #this generates a histogram from the previous data
bar_chart(b) # this is where I get the following error:
NotImplementedError: Unable to parse output
```

Is this something that has not been implemented as the message suggests or am I doing something wrong?

Did you mean `b = octave_hist(a)`?

Good question, though. I tried `b.sage()`, but also raised a NotImplementedError
