Hi. I did a pie chart with a field that have a numeric value that represent the code of a operation. This field is called oper. So in this field I can count how many kinds of operations occurs in 1 day. So in the pie chart I can see, for example, that there was 5 operations with the code 2 and 10 operations with the code 7, etc. So, until this point everything is fine. But I need to put the name of the code operation in the legend of the chart. I mean the code 2 operations are yellow operations, and the code 7 are de blue operations. So in the legend of the pie chart I need to display this yellow instead of 2 and blue instead fo 7 and so on for all de codes operations. Something like tihs. ``` "legend" 2 - yellow ``` this is 5 - red my 4 - black pie chart 7 - blue I have the list of the codes in a Excel file. The names doesn't come in the info that are being inserted on Elasticsearch. ---

I would use a scripted field for that. To get started, see - [https://www.elastic.co/blog/using-painless-kibana-scripted-fields](https://www.elastic.co/blog/using-painless-kibana-scripted-fields) - [https://www.elastic.co/guide/en/kibana/current/scripted-fields.html](https://www.elastic.co/guide/en/kibana/current/scripted-fields.html) Write a script that maps each code to a readable name (2-\>yellow, 7-\>blue, ...) Then, make your pie-chart using the scripted field instead. ---
