Help with custom Gantt from Madison Giammaria
Hi all! I just came across an incredible looking Gantt from Madison Giammaria, built with the Deneb custom visualiser. I have been trying to produce the core functionality using my own dataset but after countless attempts I am not able to produce the visual in Power BI. I have no idea what is causing this issue and I was hoping to leverage the expertise here. Steps so far: Downloaded the Deneb visual and latest json code from the github repo. Mimicked the data, renamed my visual field names to match the expected value. Tried changing my table names directly to see if that helped. I have confirmed the data types and format match whats expected, by leveraging the example pbix provided. I even replicated the "root" row to see if that helped. Expected view: My current view: The Log errors show: [Error] Cannot read properties of undefined (reading 'enabled') [Error] Cannot read properties of null (reading 'length') As you can see nothing is generating within the visual itself, and I am completely lost to what the problem is. I appreciate any and all help. I know this would be extemely powerful to use for my use cases and would like to get it working. Thank you, Tom
Deneb | Vega-Lite tooltip issue
With much help from giammariam , I have a Deneb custom visual that is exactly what I want--except for the tooltip. Deneb is displaying the tooltip for the highlighted null data point as 0.0%. I would expect to see a blank. Here is the relevant part of the tooltip block from my spec: { "field": "Growth (month over year-ago month)", "type": "quantitative", "format": ".1%" }, This works great except for the display of the last data point, which again should be blank, null, "n/a" or something of the sort. Appreciate any help.
Deneb - measure totals not showing correct value
Hi, I have an issue with a deneb visual which is not showing the measure values properly. It calculates the rows seperately split by descriptions and then adds them together which is a different out come. Example: This is how it should be: ID Count hours Total Units Out come 1 10 92 9.20 What happens is: ID Count hours Total Units Out come 1 5 47 9.4 1 8 45 5.625 this totals 15.025 It counts some hours double as it considers the description (there are 4 descriptions). So you can have as 2 descriptions in 1 hour, so it doesn't count it as 1 but as 2.... When I remove "Description" from the visual values, the measure shows correctly, but I need the "Description" so removing it is not an option. To fix this I wanted to use transform, but this allows me only to use in on one measure and not on two... The below doesn't work. "transform": [ { "aggregate": [ { "op": "sum", "field": "Count of Hours", "as": "totalHours" } ], "groupby": ["ID", "Other ID"] } ], "transform": [ { "aggregate": [ { "op": "sum", "field": "Total Units", "as": "totalUnits" } ], "groupby": ["ID", "Other ID"] } ] With the standard power bi visuals I don't have this problem... but those limit me with the visual I want to create If somebody knows what can be done to fix this or has another way to solve this issue that would realy be appriciated. Thanks in advance.
