Wordcloud may have bugs


First, it seems the selection method of wordcloud chart is not based on frequency. If the size of word set is less than 10, it gives me a blank chart. It may be a bug.
Second, the input of wordcloud is not friendly. Why does it only accept repeated words, rather than (word, count)?
In real case, I often filter very low freq words:
SELECT key_word, count(1)
FROM events
GROUP BY key_word
ORDER BY count(1) DESC limit 100
Now how to convert [(word, count), …] to [word1, word1,… word2, word2…]?


I’ve found the same issue and it’s an open issue on github https://github.com/getredash/redash/issues/1414
