How to visualize two rectangles in Power BI - powerbi

How to display two rectangles, on inside the other in a Power BI visual? Of course, given rectangle coordinates and sizes. Preferably using native visuals.
Example:
Bigger rectangle (frame) size is width:10 hight:8
Inside Rectangle size is width:3, hight:2, x:4, y:5
I do not care about the display of the numbers or axes. Just the blue and red rectangles.

In case you change your mind, here is a Vega-Lite version. You can literally just drop the code into Deneb and don't need to do anything else.
{
"$schema": "https://vega.github.io/schema/vega-lite/v5.json",
"width": 300,
"height": 240,
"background": "#9bc2e6",
"data": {"values": [{"x": 3, "x2": 6, "y": 4, "y2": 6}]},
"mark": {"type": "rect", "color": "#c00000"},
"encoding": {
"x": {
"field": "x",
"type": "quantitative",
"scale": {"domain": [0, 10]},
"axis": {
"gridColor": "white",
"gridWidth": 1,
"domain": false,
"title": "x",
"orient": "top"
}
},
"x2": {"field": "x2"},
"y": {
"field": "y",
"type": "quantitative",
"scale": {"domain": [8, 0]},
"axis": {
"gridColor": "white",
"gridWidth": 1,
"domain": false,
"title": "y"
}
},
"y2": {"field": "y2"}
}
}
Edit:
You mean like this?

Setting a dynamic domain in Vega-Lite (Deneb)

Another week, another Vega-lite question I´m turning to you guys.
It´s actually pretty easy to create KPI cards in Deneb however what´s causing me headache is the positioning of marks.
As you can see on the picture below when the delta is positive it´s pushing the line to the top and when negative then to the bottom of the visual. I´ve tried to set fixed axis which solved my problem however it was not right because you have KPIs where the delta range differs most of the time. So I can´t put a range [-15%,15%] because at KPIs where range is between [-2%,2%] it´s creating a flat line basically. And I don´t want to set axis KPI by KPI separately.
Not even talking about when adding a text label to the visual it can be pushed out from the picture.
Do you have any idea of a workaround that could solve this issue?
Thanks a lot!
The domain can be calculated dynamically as +/- 10% from your data. e.g. this example with no fixing.

{"x": 1, "y": 10},

{"x": 5, "y": 10},
{"x": 6, "y": 10},
{"x": 7, "y": 10}

},
"mark": {"type": "line", "point": true},
"encoding": {
"x": {"field": "x", "type": "quantitative"},
"y": {"field": "y", "type": "quantitative"}

How do I use aggregates in grouped marks?

I'm trying to use the min and max aggregates of a quantitative column (Total bombers) grouped by another column (Country) in a rule mark of my visual. I want the rule y property to start at the minimum value of Total bombers and the rule y2 property to end at the maximum value of total bombers, but I can't seem to find the right syntax for the min and max aggregates of the rule mark. I can get the result I'm looking for by not grouping the marks but I would like to implement it for grouped marks so I can re-use it more easily.
Spec for grouped version I'm trying to use min and max aggregates in:

Any help much appreciated!
What you're trying to do isn't logically possible. You have faceted on country. That means each country gets a line (working), a symbol (working) but how would it get a rule where the start point is one country and the end point is the other. One group does not know anything about the other group so you couldn't have a rule spanning the two countries.
If you want to keep your facet, you can do the following:

how to create a shape with min and max values power bi

I have a data below:
xmin xmax ymin ymax
2 4 1 2
4 6 2 3
I wanted to generate a shape which I can use to fill in values. Please assist.
Thank you
Create your data like this.
Make sure every column says do not aggregate.
Import the Deneb visual from marketplace.
Add the fields to the Deneb visual well as follows:
Paste the following code into Deneb.
{
"$schema": "https://vega.github.io/schema/vega-lite/v5.json",
"width": 300,
"height": 240,
"background": "white",
"data": {"name": "dataset"},
"layer": [
{
"mark": {"type": "rect", "color": "#9bc2e6"}
}
],
"encoding": {
"x": {
"field": "xmin",
"type": "quantitative",
"scale": {"domain": [0, 10]}
},
"x2": {"field": "xmax"},
"y": {
"field": "ymin",
"type": "quantitative",
"scale": {"domain": [8, 0]}
},
"y2": {"field": "ymax"},
"color":{"field": "id"}
}
}
That's it.

Can I partially color a bar based on percentage complete on a temporal axis?

I am trying to create a Gantt chart and I want to color a single task with two colors, based on a percentage complete. Say, make the complete part green and the remaining part orange.
How can I achieve this?
Below is a sample code, also available in the editor here.
{
"data": {
"values": [
{"Description": "Task 1", "Start": "2023-01-05", "End": "2023-01-10", "Percentage complete": 0},
{"Description": "Task 2", "Start": "2023-01-01", "End": "2023-01-15", "Percentage complete": 75},
{"Description": "Task 3", "Start": "2023-01-01", "End": "2023-01-03", "Percentage complete": 100}
]
},
"layer": [
{
"mark": "bar",
"encoding": {
"y": {
"field": "Description",
"type": "ordinal",
"stack": null
},
"x": {
"field": "Start",
"type": "temporal"
},
"x2": {
"field": "End",
"type": "temporal"
}
}
}
]
}
The expected result should look like this.
I tried looking at folding, transforming, and scale. But as I am new to Vega-lite, to no avail.
You have two options.
Reshape your data upstream. Your partially coloured bars should be rendered as two bars stacked - one for incomplete and one for complete.
Use Reactive Geometry as described here. This may need Vega rather than VL.
Here it is using reactive geometry.

How do you change the font formatting of a single axis label value

I have a text field ['Region'] with four values {Global, AMER, APAC, EMEA}. I have a simple bar chart and want the label to be bold only for 'Global' but have been unable to do so.
I tried:
{
"$schema": "https://vega.github.io/schema/vega-lite/v5.json",
"data": { "values": [
{"Region": "Global", "Months": 1, "RegionRank":1},
{"Region": "AMER", "Months": -1, "RegionRank":2},
{"Region": "APAC", "Months": 3, "RegionRank":3}, {"Region": "EMEA", "Months": 2, "RegionRank":4}
]},
"layer": [
{
"mark": {
"type": "bar",
"filled": false,
"stroke": "gray",
"strokeDash": [3.6],
"strokeWidth": 3
}
},
{
"mark": {
"type": "text",
"fontSize": 14,
"xOffset": {
"expr": "datum['Months']<0 ? -15:15"
}
},
"encoding": {
"text": {
"field": "Months",
"format": "+.0f"
}
}
}
],
"encoding": {
"y": {
"field": "Region",
"type": "nominal",
"axis": {
"offset": 10,
"title": null,
// problem section
"labelFontWeight": {
"condition": {"test": "datum['Region'] == 'Global'","value":"bold"},
"value":"normal"
}
},
"sort": {
"op": "min",
"field": "RegionRank",
"order": "ascending"
}
},
"x": {
"field": "Months",
"type": "quantitative",
"axis": {"title": null}
}
}
}
but there is no change to the label font weight.
What is interesting is that I switched the result conditions, making the '==Global' result "normal" and the else "bold" and it changed font weight on all the labels to bold. That leads me to believe that my condition is never being evaluated as true. Any ideas why? Is what I want to do - changing a signal value in an axis label - possible?
You mean like this?
