I have a 3 column chart: Time of day (independent variable), systolic & diastolic pressures (dependent variables). Time of day is random, inserted using the "NOW" button. I plot this data daily on a simple 2D line graph. The X axis always plots in constant increments.

Is there a way to get the spacing on this axis to vary in accordance with the random times of day?

The only way I can think of is to pre-create a row for each time you need to record. Depending on how granular you need this to be it could be morning/noon/evening, or hourly (one row per hour).

That, of course, can make for some really long tables.

I once created a time chart using the table itself. I created a column for each 30 minute's of a day, along a row. I doubt this would server your needs, but it might give you some ideas.

There are values in the cells, for computation purposes, but I made them the same color as the cell background so they would not distract. I image you'd want to do the opposite. Though you could change the background colors of the cells to reflect high/good/low blood pressures results.

I hadn't thought of that. The latest version of Numbers does support scatter charts; both static and interactive.

I really need to explore the new chart types and find out what I can do with them.

Well, thanks again. I know that there are updates available for both NUMBERS and PAGES, but, I have no broadband available where I live to download them. Next time I get into a civilized area I will update all of my apps.

There are several apps on the app store which are used for keeping track of blood pressure results, some free, some paid. I use BPCompanion which is free and very good. There is also a paid version which can deal with multiple users. Graphing is a feature of all of them. Suggest you might like to investigate,

Now, why didn't I think to look for an app for this purpose!

Thank you very much.

I have downloaded this app and am experimenting with it.

Have you found a way to add comments to a data point, such as "after vigorous exercise"?

Negative. However it does include heart rate, vigorous exercise would presumably increase this.

Your reply about no comments is odd as I notice the second entry under features for that app is "add note to the readings"!

Ooppss ! Do you know I have been using this app for months and never noticed that the new data entry screen has 3 separate sections. One to enter timed and dated bp readings and heartrate, another to add weight, and finally to add a short note. I suppose it's a case of you only use an app as you want to. If a note is added it appears at the right of the screen, and ALL data can be exported in a variety of ways including xls and pdf files. Wow. That makes it even more of a useful tool. Sorry I misled people.

I find that often if you spend some time just exploring what an app can do, it often will do a lot more than you first thought.

When someone recommends a free app of interest to me, I generally just download it and dive into it. If I can't readily figure it out, delete it.

In the case of BP COMPANION, it was straightforward and intuitive. Don't like entering numbers with a dial, though. I can enter 3 digits faster & more accurately by typing them in.

I've just downloaded the free version for myself - thanks for mentioning it!

Does anyone know if it is possible to put previous readings in or does it only log numbers for the current date/time?
