Hi there,

I would like to understand how canvas is used, where it's limitations are and if it suits to my usecases.  
I tried to play with it a bit, but I did not get familiar with it yet.

1. On all demos I saw, it always showed the most recent data. Is it possible to select a time range like in the classical dashboards?
2. If I use the table element, can I do some value based formatting? e.g. color the line red if field status is error, color it green if it is ok?
3. Can I do some post calculation in the table element? If I have two timestamps per line in a table. Can I calculate the difference and show it?
4. Is it possible to use filters like in the normal dashboards? Filtering by clicking on fields, select a time span in histogram by mouse interaction?

My hope is, that I can create some dashboards (especially with tables and line diagrams) where I can color or change images based on the value of some fields.

Thanks, Andreas

Regarding the filtering, there's ongoing [work](https://github.com/elastic/kibana/issues/19813) for generalizing filters and bringing more capability for Canvas, for an upcoming release. In the meantime, filtering could be done with Canvas Functions which used to be [here](http://canvas.elastic.co/reference/functions.html), due to bringing Canvas into the Kibana repository this link seems not to go to the proper place but there are some [examples](https://discuss.elastic.co/t/canvas-blog-stream/126823/38?u=monfera). Using a SQL subset is another option, some examples are [here](https://www.elastic.co/blog/kibana-canvas-metric-and-markdown-elements).
