Excel Indicator

The Excel Indicator is an indicator that uses a Microsoft Excel File to do the calculations. Spatial information can be send to the Excel spread sheet and score and explanation information is retrieved from the file to be displayed in the Indicator Panel.

Please note that the full version of Microsoft Excel is required, as the file format used is the xlsx-format. Also, we can not guarantee that other (open source and online) packages offer the same functionality as the full version of Microsoft Excel, such as expandable entry fields for longer cell names.

How is the Excel Indicator implemented in the Tygron Engine?

The Tygron Engine uses spatial data sets from different sources. If this data contains information that can be retrieved with a query, a dedicated indicator can be created by the user to process this data, in the form of an (xlsx) Excel Spread Sheet. A change in the project state provides input to the indicator, the indicator spread sheet performs calculations based on this input and displays the result as output in the indicator and progress panel on the top bar.

Detail from sample Indicator Excel File

To understand how to implement the Excel Indicator, please read the Prerequisites and Quickstart.

Prerequisites

In order for the Excel indicator to work, it must contain the following named cell:

• EXPLANATION

And either one of these two:

• SCORE
• SCORE_MAQUETTE AND SCORE_CURRENT

The Explanation Text can contain %s parts, which will be replaced by cells named subsequently:

• VAR_0
• VAR_1
• VAR_2, and so on..

If the Explanation Text contains more n %s parts, VAR_0 to VAR_(n-1) should be present as named cells.

Upload an Excel file

To upload an Excel for the Excel Indicator, please click on the upload button and select the Excel file in the file chooser that pops up. A file with the same name can be uploaded over and over again, the file will simply replace the previous one.

Quick Start

This section contains a short quick start on how to create an excel that will be able to perform as an Excel Indicator in the Tygron Engine.

Example Setup

First create a new blank Excel, or use an existing one. In the image below you can see a created Excel with Function Categories. As an example, we are interested in calculating the percentage per construction type that are within a safe zone. In the Tygron Engine, a Terrain with the type Safe Zone has already been created.

Naming Cells

In order to get the amount of Floor Space of constructions within the SafeZone, a Cell can be given a particular Name:

The Name is shown in the upper left text field in the Excel. This Name is actually a query command that can be interpreted by the Tygron Engine, also known as TQL. In this case it says:

SELECT_FLOORSIZE_WHERE_CATEGORY_IS_SOCIAL_AND_MAP_IS_MAQUETTE_AND_TERRAINTYPE_IS_SAFE_ZONE

This query is not hard to read or understand. To retrieve the total amount of Affordable (Social) Housing, the query is as followed:

SELECT_FLOORSIZE_WHERE_CATEGORY_IS_SOCIAL_AND_MAP_IS_MAQUETTE

Also see the image below:

Name Manager

The naming of cells should be done carefully, because making a mistake here will result in an error during the calculation of the Excel Indicator. Also note that, once a cell has been named, the Microsoft Excel Name Manager must be used to edit the name of the cell. This Name Manager can be opened as followed:

Here you can find all defined names in your Excel and to what cells they refer. If you want to edit a cell name, click on the Edit Button. The following panel will appear:

Fixing Name Problems

In this panel you can edit both the name as the cell it refers to. This is the easiest way to correct a label. Note that you can also refer two labels to the same cell, something that happens quite often during renaming. The image below shows a Cell with two references. Both a MAQUETTE as a CURRENT query are referring to the same cell. One will override the other and the order is unpredictable. Make sure you resolve these issues. You can delete the name, or let it refer to another cell.

Generate Scores and Explanations

In order to generate scores and explanations, you need to have either one named cell: SCORE, or two named cells: SCORE_CURRENT and SCORE_MAQUETTE. In Planning games, the SCORE_MAQUETTE is most used, in TimeLine games both are important to indicate the difference between the planned situation and the current situation.

• Excel quick start 8.jpg

Last but not least is the explanation. This is the text shown in the lower left corner of the Indicator panel during a game session. The explanation text can be written in html format. The cell should be named EXPLANATION. Note that when using explanation texts, you also want to include numbers and or text calculated by your excel. You can include '%s' values, which will be replaced by VAR_# cells, starting from VAR_0. See also #Prerequisites.

Tips

• Divisions by zero can be solved as followed: =C2/IF(D2,D2,1). In this example cells C2 and D2 contain number values.
• Instead of using the VAR_# method for the explanation text, you can also use the concatenate function of excel:

CONCATENATE("<nowiki>

",A2, ": ", E2, " m2 and in Safe Zone: ", F2, " m2

")
