Good morning,  
I have a doubt, i have an index with a lot of values of a field with null values in search. When i plot this field in line chart of kibana this all values appears with the 0.00 value. Why catch the value 0.00 if really is null or -? How can i delete this value from the chart if in the same register there are 2 diferent fields that i plot too and they are'mt null?

Can you share more details on your data, and show how your chart is configured? I threw together a quick line chart using an index with null values, and it rendered properly without any dips to 0:

I think so; you're trying to avoid these dips:

If you were to omit the null values, what would you expect to see in its place?  
You could set the "missing" property on your sum metrics to provide a fixed value if it's missing:
