Showing a chart with grouping based on parameter

[Anonymous]

I have a weekly number of issues, and each issue has a category: device_type, source, priority, site name.

How can I create a graph which shows the number of problems per week, but the splits will be different based on which categoty split I select?

e.g.

For the following graph, I picked a legend: Prio (priority), but I also want the user to pick other and this to update accordingly:

For prio:

For device category:

For site name:

Please use Field Parameter for that. There are tons of videos in Youtube regarding Field Parameter. Learn that concept and use that.

Hope it will help.

Thanks @sanalytics , I am following a tutorial on youtube and creating the parameter:
(each of these parameters are categorical

Parameter = {
("Device Category",NAMEOF(source[Device_category]),0),
("Site Name", NAMEOF(source[SiteName]),1),
("Prio", NAMEOF(source[Prio]),2),
("Completed", NAMEOF(source[Finished]),3)
}

But this gives me an error "The expression refers to multiple columns. Multiple columns cannot be converted to a scalar value."
And I don't understand how to fix it in this context.

Chat GPT tell me to use the following but this does nto work either.

Parameter = {
    ("Device Category", source[Device_category], 0),
    ("Site Name", source[SiteName], 1),
    ("Prio", source[Prio], 2),
    ("Completed", source[Finished], 3)
}

Do you have a tip what is wrong with it?

I got it to work with picking fromt he ribbon "New parameter" rather than typing, and it looks the same to what I wrote, and this one works:

Parameter = {
    ("Device_category", NAMEOF('source'[Device_category]), 0),
    ("Finished", NAMEOF('source'[Finished]), 1),
    ("Prio", NAMEOF('source'[Prio]), 2),
    ("SiteName", NAMEOF('source'[SiteName]), 3),
    ("Source", NAMEOF('source'[Source]), 4),
    ("OTD", NAMEOF('source'[OTD]), 5)
}
