Online help: Diagram data

An item has inputs and outputs. In the data form of an item you can see additional rows for the summed up total values. Please note, that you can enter values followed by a unit and you can enter the unit in the separate column which is sightly different.

Item data follows different logic types:

• auto adjust: The values of the inputs and outputs are independent from each other and can be changed automatically.
• user input: The values of the inputs and outputs are independent from each other. They can NOT be changed automatically and they appear in the diagrams data from.
• fix ratio: The values of the inputs and outputs are dependent. If e.g. one value is doubled, then all other values are automatically doubled too.
• sum up (in->out): There is just one output. The values of the inputs and outputs are dependent. The single output value equals the sum of all input values.
• sum up (out->in): There is just one input. The values of the inputs and outputs are dependent. The single iput value equals the sum of all output values.

The dialog for connection data details pops up when you click at the "..."-button in the connection data form. The dialog has 2 purposes:

1. Value type: For connection ends, which are not connected to an item, there is a value type similar to the logic types "auto adjust" and "user input" of an item.
2. Trunk: This dropdown is required just in special cases, when a connection has multiple producers AND multiple consumers.

What happens, when I change a value?

• 1 producer, 1 consumer: The other value is set equal to the changed value.
• n producers, 1 consumer: When an producer value is changed, the consumer value is adjusted appropriately. When the consumer value is changed, ALL producer values are adjusted proportionally.
• 1 producer, n consumers: Similar to the case above.
• n producers, m consumers: When the value of the trunk (see above) is changed, ALL other values are adjusted proportionally. Otherwise the trunk value is adjusted appropriately.

If one or more items of the diagram are classified as "user input", then the diagrams data form provides a structured view on the input and output values of these items.

Depending on your license, you can customize the diagrams data form. (see below)

The parameter dialog can be opened with the "f(x)"-buttons in the item data form and the diagram data form.

You can add parameters to an item and you can add parameters to the diagram itself.

A parameter has a name starting with an alphabetic character or an underscore and contains no white space or special character (+-*/...)

The second parameter field can contain a numeric value or a mathematical formula (see below).

The "unit" field of a parameter is optional. In case you plan to show the parameter in a customized diagram data form, you should give it a reasonable value.

The "comment" is also an optional field. You can e.g. explain the mathematical formula or give a hint to the parameters purpose.

Following operators and functions can be utilized in mathematical formulas:

Operators: +, -, *, /, ^

Logical operators: <, <=, =, >=, >, #, and, or

Functions: if, sin, cos, tan, asin, acos, atan, rad, deg, ceil, floor, abs, exp, int, round, sqrt, sqr, max, min, log

ATTENTION: The functions "min", "max" and "if" accept multiple arguments. Make sure that you apply the list separator specific to your country settings. E.g. US: "," (comma), Germany: ";" (semicolon)

The "if" function has following pattern:

if (condition, valueIfTrue, valueIfFalse)

The "condition" is a logical expression (e.g. "a > b", "(c > 5) and (c <= 10)"), the other values are numeric or formulas. If the condition is true, the "if"-function results in its second argument, if the condition is false, it results in the third argument.

References to parameters

Parameters are associated to a "scope": an item or to the diagram itself. We can distinguish three different cases of parameter references:

• Same scope: Just use the parameter name.
• Diagram parameter from item scope: Write two dots ".." in front of the parameter name. ".." means "one level up".
• Parameter of another item: Use a parameter path with an item name, separated by a dot "." (see examples). The item name is the first line of it's caption. If it contains white spaces or special characters, it must be written in double quotes. (The automatic dropdown does help you to reference just existing parameters.)

• A * 5
• (alpha + beta) / (x + 1)
• ..globalX * (A + B)
• ..item2.alpha - 2
• ..globalX * sin(..item2.alpha) + A
• if(..globalY > 0, A + B, .."item 3".beta * 5)

To open the dialog to edit a data form, click at the (white) diagram surface to select it and below "Data" click at the second button "Edit form".

The "Edit form" dialog shows an extended view of the data form. You can drag lines and groups to another position. Click at a line to change the text or the referenced value.

Value input

Input field to change a data value. Just numeric values can be referenced. Each data value can be referenced just once in a data form.

Examples:

• in: A
• out: B
• parameterC

Value display

Output field to display a data value. All data values (numeric, formulas and "auto adjusted") can be referenced multiple times in a data form.

Examples:

• in: A
• out: B
• parameterC

Text

Text field for additional explanations or comments.

Example:

• "The diagram is designed to show XXX of a single day. It shows reasonable results, just if the sum of all durations do not exceed 1440 min (= 24h)."

Group

Structural element which can be collapsed to a single title line. Groups can be nested.

Examples:

• Personal information
• Activities
• Workout

Attribute

Textual input field for diagram attributes. Attribute values can be shown in diagram titles and item captions. (Please see the advanced tutorial)

Examples:

• Month
• Day
• Region

To open the "scenario" dialog, click at the (white) diagram surface to select it and below "Data" click at the third button "Scenarios".

Depending on the attributes of the diagrams data form, there are folders to structure the scenario list. (Please see the advanced tutorial for a detailed explanation.)

Hint: In our tutorial, we decided that our diagram should hold just scenarios of a single year. Therefore, we added the attributes "Month" and "Day" (and not "Year"). For the next year, we planned to create a copy of the total diagram including the scenarios.
