	Once you have selected the month and have pushed the View Selected Month button, you will be presented with a page listing all the data entries for that month. The green weight values are the measurements that you have entered. The yellow weight values are trend weights, calculated with one of the formulae shown above. If you press on one of these entries, you will be sent to the Data Entry page, which will be preloaded with the selected day's values, where you may change the values. You may also press the Delete button to remove the entry entirely.

	The ~~remaining~~ buttons control the time range for the plot. If you select Plot Interval, you will be presented with a range of standard time intervals for the plot. If, for example, you choose Plot Last Month, then all the data enterred in the last 30 days will be plotted. If you select Plot Date Range, you can set a custom time interval by specifying the starting and ending dates for the plot. You can also specify just one date, and have the program plot all the data before or after that date.		The next set of buttons control the time range for the plot.

You can also specify just one date, and have the program plot all the data before or after that date.

			The final set of buttons at the bottom of the page allows you to specify the time range used for the weight loss summary printed at the bottom of the plot. By default the app calculates how much weight you've lost of gained during the last week, and uses that number for calculating the daily caloric deficit or excess. These buttons allow you to change that interval.

	~~[[Image~~:~~maeFatSettings.png\|thumb\|200px\|alt=maeFat Settings\|Settings]]~~		There are three pages which allow you to change how the program operates:

	The ~~Settings~~ page ~~allows you to change how the program operates. It~~ must be used ~~initially~~ to enter your height. ~~Before entering~~ your height, you should select centimeter units if that's what you wish to use (rather than inches). You may also select metric units for weight, and the ~~format for displaying~~ the ~~dates~~. If you ~~select nonjudgemental colors~~, ~~neutral colors~~ will be ~~used to display the data, otherwise~~ green will be used to ~~indicate~~ weight ~~loss~~, ~~red~~ will ~~be used for~~ weight ~~gain~~, ~~and~~ the BMI ~~data will be color coded~~. The BMI color code is:		=== About You ===

			[[Image:maeFatAboutYou.png\|thumb\|200px\|alt=maeFat About You\|About You]]

			The About You page must be used at least once, to enter your height.
			When you enter your height, you should select centimeter units if that's what you wish to use (rather than inches). You may also select metric units for weight.
			You may also set a target weight, which can be displayed as a green line on the weight vs time plot, and which will be used to calculate when you will reach your goal. You may set a target date, which will cause the Trend Analysis page to show how many more (or fewer) calories you must consume per day in order to meet your goal weight by the goal date.

			You may specify whether your goal is to gain or lose weight. That selection controls the colors shown in some plots and text boxes. For example if your goal is to lose weight, and you are in fact losing weight, the rate of
			weight change shown on the Trend Analysis page will be shown in green. Otherwise it will be shown in red.

			The Hacker Diet button controls the formula used to calculate the trend weight (see explanation below). The Start With Data Entry button controls what is shown when the program begins running. By default the weight vs time plot is shown, but if you check the Start With Data Entry the program will initialize on the page which allows you to enter a weight value, which can save a few menu navigation steps.

			=== Plot Settings ===

			[[Image:maeFatPlotSettings.png\|thumb\|200px\|alt=maeFat Plot Settings\|Plot Settings]]

			The Plot Settings page controls the main weight vs time plot. The Plot Target Weight checkbox controls whether or not your goal weight in shown on the plot. The Plot Comments checkbox controls whether any comments you have entered along with your weight values get shown on the plot.

			By default, things which are usually considered bad, such as having a BMI in the obese range, are shown in red. Good things, like losing weight when your goal is to lose weight, are shown in green. The BMI color code is:

	* '''Red''': Obese or Severely Underweight		* '''Red''': Obese or Severely Underweight
Line 36:		Line 55:
	* '''Green''': Normal weight range		* '''Green''': Normal weight range

	You ~~may also set a target~~ weight~~, which can be displayed as a green line~~ on the weight ~~vs time plot~~.		You can suppress all this color coding with the Nonjudgemental Colors checkbox.

			The Plot Trend Line checkbox controls whether or not the exponentially weighted average weight value is shown on the plot. The Plot Data Points checkbox controls whether or not your individual weight entries are plotted.

			There is a set of three buttons which controls the format used to print dates throughout the program.

	~~Selecting "~~Plot ~~Trend Line" (~~the ~~default)~~ will ~~show~~ a plot of the ~~exponentially weighted running average of~~ the ~~weight~~ data.		The remaining buttons control the time range for the plot. If you select Plot Interval, you will be presented with a range of standard time intervals for the plot. If, for example, you choose Plot Last Month, then all the data enterred in the last 30 days will be plotted. If you select Plot Date Range, you can set a custom time interval by specifying the starting and ending dates for the plot. You can also specify just one date, and have the program plot all the data before or after that date.

	There are four "radio box" sets of buttons. The first allows you to set whether your goal is to lose weight or to gain weight. The green/red color coding of weight changes will be set depending upon this setting. The second set of buttons allows you to define the format for printing dates. The		=== Fit Settings ===
	~~third set of radio buttons lets you set~~
	~~the time interval for the default weight vs time plot. The fourth radio box contains buttons which allow you to define whether or not a least squares fit~~
	~~is applied to the data, and the time interval over which the fitting should~~
	~~be done.~~

	~~For the least squares fit time interval, you may chose either "Fit Interval" or "Fit After Date"~~. ~~If you chose "~~Fit ~~Interval", you may then select a window which specifies the time range for the data that will be fit. For example, if you select "~~Fit Last Month" then the weight log entries for the last 31 days will be used for the least squares fit. If you select "Fit After Date", then you may select a specific date after which all the weight log entries will		[[Image:maeFatFitSettings.png\|thumb\|200px\|alt=maeFat Fit Settings\|Fit Settings]]
	~~be used for the least squares fit. To disable least squares fitting, select~~
	~~"Fit Interval" and "Don't Fit Data".~~

	~~There is also~~ a ~~button labeled Start with Data Entry~~. ~~Selecting that option~~		The Fit Settings page allows you to specify a time range overwhich the program will perform a linear least squares fit to your data points. This least squares fit will be used to estimate the time at which you will reach your goal weight. This is shown on the Trend Analysis page. Also, if you tell the program to plot your goal weight, the linear fit will also be shown on the plot, along with the slope which tells you how many pounds (or kg) per week you are losing or gaining.
	~~causes the app~~ to ~~show~~ the ~~data entry dialog page as the first page when maeFat~~ is ~~started, rather than~~ the ~~plot~~ page. ~~This can save a little time~~ if you ~~run~~ the ~~app once a day~~ to ~~enter a daily~~ weight ~~measurement~~.
