Setup

• MW version: 1.35.5

• PHP version: 7.4.14 (cgi-fcgi)
• SMW version: 3.2.3
• SRF version: 3.2.0

Issue

Hi, I am a new SMW and SRF user and need some help! I tried to repeat an example of a chart from here but it does not work for my wiki and I don't know why.

Steps to reproduce

I have a [[Category:City]] and 4 cities inside: Berlin, Munchen, London, Moskow. Each city page have similar text:

[[Located in::Germany]]
[[Population::1234979]]  
[[Average rainy days::130]]
[[Area::87600]]
[[Category:City]]

On page of Category:City I write: {{#ask:[[Category:City]] | ?Population | ?Average rainy days | ?Area}} and have a result: It's working, but when I try to use a chart:

{{#ask:[[Category:City]]
|?Population
|format=jqplotchart
|link=all
|headers=show
|searchlabel=… further results
|distributionsort=none
|direction=vertical
|numbersaxislabel=Population
|height=400
|width=50%
|valueformat=%d
|ticklabels=1
|theme=simple
|filling=1
|chartlegend=none
|datalabels=percent
|charttype=bar
}}

I have a warning about data: "Warning The requested data cannot be displayed due to insufficient selection criteria."(c) Translator But when a add |distribution=yes to parameters, I have: The same problem with other charts formats excluding googlepie and googlebar - they are working well. I think the problem is in data format, but I can't be sure and don't know how to fix it. Please help me to solve this problem. Link to my test wiki on temporary hosting (becoz sandbox is not avaible). I'm newbee on Git and if I was wrong in the place for my simple question - please tell me where to go.

Looks like your properties are not of type number. Hence the red numbers (with links to non-existing pages) in the table. Properties are of type page by default and they should be of type number for your.

Thank you! I didn't even know properties have types.
