Hello, i know this is an outdated problem, but after i research all the topic about dropdown canvas and implement it, the result always zero data i don't know why.

So, right now i want to developed a simple visualization using bar chart and drop down filter

this is the code for bar chart :

filters group="app" ungrouped=true  
| essql  
query="SELECT sum(count\_total) as count\_total,app\_name,payment\_step FROM "funnel\_canvas\_index\_dummy" GROUP BY app\_name,payment\_step"  
| pointseries x="payment\_step" y="count\_total"  
| plot defaultStyle={seriesStyle bars=0.75} legend="sw"  
| render

this is the code for filter :

essql query="SELECT app\_name FROM "funnel\_canvas\_index\_dummy"  
group by app\_name"  
| dropdownControl valueColumn="app\_name" filterColumn="app\_name" filterGroup="app"  
| render

is the way that i do it wrong or something ?

thanks before

Hi @Timothy_Julius, if the bar chart is empty when you select a value from the dropdown, sometimes this can be due to how the data is indexed into elasticsearch. See if you have a "app\_name.keyword" field, you can read about keyword here: [https://www.elastic.co/guide/en/elasticsearch/reference/master/keyword.html](https://www.elastic.co/guide/en/elasticsearch/reference/master/keyword.html)

Keywords enable filtering by an exact match which may help in this case.

If that doesn't work, are there any other filters in the "app" group?
