Hello, I'm trying to visualize the price of gold through a month but I only have values for weekdays, so the value for weekends is null. Using min\_doc\_count I can take out the nulls but I want the weekend to have the same value as friday without creating new logs. How can I do this?  
Thank you!

I think you should be able to create this behavior using **timelion**.

Try something like this:

```
.es(index=logstash*,
    timefield='data',
    metric='min:cena').fit(carry)

```

The [carry option](https://www.elastic.co/blog/sparse-timeseries-and-timelion) interpolates missing data using the latest available data.

If you need to apply additional filtering, you may use the [timelion if function](https://www.elastic.co/blog/timeseries-if-then-else-with-timelion) as well.

Hope this helps,

We are working on enabling this in other visualization types, a change was recently merged to our charting library which will hopefully make its way into various editors soon: [https://github.com/elastic/kibana/issues/17717](https://github.com/elastic/kibana/issues/17717)

I tried to use Timelion but I can't define the timefield to be "data". With .es(\*) I can see that all the logs are being read correctly but timefield='data' does nothing

Hey,

The timefield is just a way to specify the name of the field according to which the timeseries is measured. Just put the column name of the timefield you have.

Thanks,
