Hi,

I am in python3 (jupyter on mac os) and I just got this weird issue, in my `go.scatter`

plot – a piece of the line is missing

any idea on what’s going on?

Thanks for your help

Paste your code and data, please. We can help you only seeing what’s wrong in your code, and data.

Sure,

here is how I am building the trace:

```
full_trace = []
full_trace.append(
go.Scatter(
x = my_df.temp_var,
y = my_df.cases,
mode = 'lines+markers',
# connectgaps=True, ## not working properly! -- connecting last w/ first
name = 'VENEZUELA'
)
)
```

and this is the subset of the dataset close to that gap

```
temp_var,cases
2017-01-08,6043
2017-01-15,8087
2016-12-18,4854
2016-12-25,3757
2017-01-01,3081
```

Did you sort the dataframe by date?

thanks – sorting the df fixed the issue

(however, I don’t see why the plot should depend on the sorting of the df)

@grgr If you remember a math function, `f:[a, b]-->R`

, is defined on an interval that is an ordered set, and to get its graph you are plotting the line passing through 2d points of coordinates (x, f(x)), with x in [a,b]. Python and other programming languages works with a discretized function, i.e. you evaluate that function at some arguments

`a=x_0<x_1<....< x_n=b`

.

Your line is defined on a time interval, that’s why you should sort the dataframe by date.
