Hello Vernal,

You might find the thread below useful! Depending on your specific use case, Vega (still experimental) might be a good fit.

Hi Aaron,

I tried Vega before. But even for one histogram, it does not work at all. I have tried about one week, but it still cannot work, which made me really frustrated. Could you help take a look what is wrong with my code? Or maybe this is caused by bugs in Kibana, not in my code?Thanks a lot!
