Day 3 of the iPad Challenge: More coding – working on the graph of bodyCal

Start of day 3 of the iPad challenge… today it is a day of graphs…

What did I do with all the extra space? Answer, I added a journal… With bodyCal for the iPad you will be able to track the changes in your body mass index (BMI) and basal metabolic rate (BMR) – great if you are dieting or just trying to watch your weight.

The goals list currently looks like this for the App:

1. Develop the interface – DONE
2. Add the body mass index (BMI) calculator code – DONE
3. Add the basal metabolic rate (BMR) calculator code – DONE
4. Add help pages – DONE
5. Add add a data summary to the interface – DONE
6. Add a graph to track BMI and BMR changes – DONE
7. Remember user settings between restarts – DONE
8. Add code to plot stored daily/weekly BMI and BMR to the graph
9. Produce an icon for the App
10. Submit to the App Store

Today, point 8 will be tackled…

On the top right hand side of the screen (top of the note book), there is a graph that tracks body mass index (BMI) and basal metabolic rate (BMR) over time. The graph works, i.e. it draws correctly, is the right size, and can accept data, but the following problems remain (this is all point 8 from above, just broken down):

1. Sending data from the calculator to the graph
2. Storing the data
3. Editing the data (i.e. removing errors, deleting data)
4. Displaying data from extended periods

Today will be spent tackling these problems, however, there is the unfortunate inconvenience of a series of meetings this afternoon that I can’t get out of… so it looks like I may only get a half day of development work in. (Shame I won’t be able to get in a full day of development, like I did yesterday…)

Right, back to coding!
