My first time trying out Canvas and I'm feeling lost. Amazingly lost. No matter what I try, I can get data showing up on preview just fine, even a simple metric shows up nicely on preview... but when I save, I get nothing on canvas. ![image](https://us1.discourse-cdn.com/elastic/original/3X/f/4/f4b2d62a5ced6f6dd9ce4977efd353c92f9f6e83.png) ![image](https://us1.discourse-cdn.com/elastic/original/3X/8/d/8d6d8ef80f4a2439827bd6ebc0151447b523abdc.png) What could I be doing wrong? I dig the documentation and found nothing at all saying anything about anything even remotely related to this kind of behavior. ---

which version are you having problems on ? On 7.3.0 released, I tried preview of elements and post the save of canvas workpad- the elements show up just fine. Is there any console error displayed? Thanks Rashmi ---

Chances are that you have some sort of filter on one of your pages that is filtering your data. Do you have a time filter or a filter drop-down somewhere in your canvas? ---

I'm running 7.2.0 - can't find a "save" option, doesn't it automatically save after every change? No errors on console. Datasource preview shows 35600 and element still shows 0. @lukas I had put a time filter in place... and now when I removed it, data showed up as it should! what the hell is going on here...? Ok, so I'm using this over data collected via [Twinttweets](https://github.com/twintproject/twint/) - there's no @timestamp field, but instead a "date". Looks like Kibana understands it nicely, but when I add time filter, all data goes away... and if I configure it to use "date" as the timefield, everything blows up: (without time filter) ![image](https://us1.discourse-cdn.com/elastic/original/3X/5/1/5146ea5c26f5fefdd89d3a732b07a82fcdb68219.png) (with time filter with default parameters is the print I've already posted on op) (with time filter and configuring "date" as the time field) ![image](https://us1.discourse-cdn.com/elastic/original/3X/4/d/4d0e69cf95347e20e72680d89314527b45eafcbb.png) Error that's showing up is: ![image](https://us1.discourse-cdn.com/elastic/original/3X/4/3/43e8985749341f467b6db329a3d4975b38e2500b.png) But discovery doesn't show date like that: ![image](https://us1.discourse-cdn.com/elastic/original/3X/c/f/cf52c998786e576ac225dd98f15305b26b339295.png) ---

Clicking on the time filter element should allow you to specify which field it uses as the date. ---

When I specify, that error in the middle shows up, the "expression failed" one, where elasticsearch fails to parse date format. ---
