Many thanks for this! This is an elegant solution!
After looking at my script, I still do not understand is how the rounding
occurs. After reading the plotly documentation, unless I am missing something,
this wasn't covered.

------ Query: ----------------------------------
Thank you. The `value` in the code example is 2874. The plot shows a large
number at the center and a smaller value computed as a delta relative to the
`reference` of 4800. But the large value is given as 2870, and the smaller
value is given as -1930 i.e. both values are rounded. Can I control the
precision of these two numbers?
------ Response: -------------------------------
In Plotly, you can control the precision of the numbers by specifying the
`valueformat` and `delta.valueformat` parameters. These parameters accept a
string in the format that is used by the C `printf` function. For example,
`%.2f` specifies a number with two digits after the decimal point. Here is an
example:
```R
plotly::plot_ly(
domain = list(x = c(0, 1), y = c(0, 1)),
value = 2874,
title = list(text = "Generic"),
type = "indicator",
mode = "gauge+number+delta",
number = list(valueformat = "%.2f"),
delta = list(reference = 4800, valueformat = "%.2f"),
gauge = list(
axis = list(range = list(NULL, 5000),
tickfont = list(size = 20, family = "Arial")),
bar = list(color = "blue"),
steps = list(
list(range = c(0, 4800), color = "white"),
list(range = c(4800, 6000), color = "red")),
threshold = list(
line = list(color = "black", width = 6),
thickness = 0.75,
value = 4800)))
```
In this example, both the main number and the delta value will be displayed
with two decimal places. You can adjust these strings to display the numbers
with the precision you prefer.
-------------------------------------------------
Here you go. I have no idea how it does this, and have a discussion on elements
of "Sein und Zeit" and book 19 of the Odyssey, and tutor me in Italian
conversation, and draft Mermaid mind-maps - but here we are.
