#### Code Sample, a copy-pastable example if possible

```python code 

import ipywidgets as widgets
import fileplot
path=widgets.Text(
    value=raw_input("Enter the Path Csv File You Want to Plot here :  "),
    #placeholder="File Path",
    #descrition="String:",
    #disabled=False  
)

button=widgets.Button(
    description='Plot',
    disabled=False,
    button_style='', # 'success', 'info', 'warning', 'danger' or ''
    tooltip='Click me',
    icon='check'
)

def on_button_clicked(b):
    #fileplot.load_file(np)
    fileplot.load_file(path.value)
 
display(path,button)
button.on_click(on_button_clicked)

**Note**: We receive a lot of issues on our GitHub tracker, so it is very possible that your issue has been posted before. Please check first before submitting so that we do not have to handle and close duplicates!

**Note**: Many problems can be resolved by simply upgrading `pandas` to the latest version. Before submitting, please check if that solution works for you. If possible, you may want to check if `master` addresses this issue, but that is not necessary.

For documentation-related issues, you can check the latest versions of the docs on `master` here:

https://pandas-docs.github.io/pandas-docs-travis/

If the issue has not been resolved there, go ahead and file it in the issue tracker.
