How to create a 2-axis chart with systolic, diastolic, and heart rate on Numbers for the same date-time?

"How to create a 2-axis chart with 3 variables (systolic, diastolic, and heart rate) on Apple Numbers for the same date-time?".

In December 5, 2025, I posted the above question here.

I got an answer of 'Yellowbox' that was what I want, except that at that time the screen of my MacBook Air 2020 was hibernating, and that answer could not be get using the iPhone.

Now, after my Mac's screen came to be awaken again, I needed more info, but that thread is terminated, and that is why I am posting it again.

"Hello,

I have started a Numbers SS with the numbers of blood pressures and heart rate, the difference between the systolic and the diastolic (below 30, turns to red), the percentual difference between them, and the 5 highest numbers (systolic, diastolic, HR, systolic - diastolic and percentual difference between the BP), that are updated at each new entry.

Actually, I am doing 2 or 3 readings a day, so there are a lot of data for each table.

I want to do a single 2-d chart for each month, showing: (i) on the x-axis, the day of the reading (2 or 3 for each day); (ii) on the y-axis I want to show the 3 readings of each measure — like each variable has an independent graph, one over the other, in the same 2-axis system: systolic, diastolic and heart rate.

The heart rate should be red, the other two should be blue and green.

The idea is that each month will be in a single sheet, and the visual of each month give the idea of how it is behaving.

The row that shows the highest reading I would like to stay as the 2nd row, always available like it is right now, but if this is not possible, I could transferred it to the bottom of the table.

The way 'Yellowbox' answered me, have less columns that mine SS, but I would like to maintain all my columns -- to have a better picture of other factors that can influence the BP while analysing the data (like date and time, temperature and the Dew Point --, although to construct the chart I will use only the data of those used on 'Yellowbox' solution: 'day' (2 or 3), 'systolic', 'diastolic', 'bpm'

How can I do that?

Any clue will be appreciated,
