Press the Browse button to select the directory that contains the graph history data.

After the directory has been selected the data is parsed. For each variable that is configured for the 2D Graph, a tab with a table will be shown in the tool. Each table consists of 3 columns:

•Human readable date and time

•Timestamp as a 64Bit unsigned value (milliseconds from 1970-01-01 00:00)

•The value at that timestamp

To clear imported data simply press the Clear button.

After data has been imported, press the Export button to show the export settings dialog.

The first step is to select what shall be exported:

•Export Selected Tab Only

If this option is selected, only the selected variable (active tab) will be exported into one csv file

•Export All Tabs in Single Files

If this option is selected, one csv file for each variable will be exported.

•Export All Tabs in One Combined file If this option is selected, one csv file will be exported that will contain all variable values with a column for each variable.

If a different separation character shall be used, this can be configured with Separator character. This can be handy because some language versions of spreadsheet applications treat the separation character differently (e.g. English Excel wants a , whereas German Excel wants a ;).

If either Date and Time or the 64Bit timestamp is not needed in the CSV file, the checkmarks of Export Date and Time or Export Timestamp can be removed.

The last step before the export can begin is to select an output file (if Export Selected Tab Only or Export All Tabs in One Combined file is selected) or an output directory (if Export All Tabs in Single Files) is selected

When all export settings are correct, hit the OK button to start the export.

The Graph History Tool is a Qt5 application and therefore has to be shipped with the matching Qt and runtime libraries. It should run on every 32Bit or 64Bit Windows version (starting with Windows 7).

The application and all the neccessary libraries can be found in the roaming files installation path of the designer application. The sub-directory is \dev\extracted_components\pclient\simulation\graph_history_tool. As long as the graphHistoryTool.exe is inside this directory, the start.bat batch file can be used to start it.

To deploy the application for the end user, copy the following libraries from the shared_libraries directory into the graph_history_tool directory:

•Qt5Core.dll

•Qt5Gui.dll

•Qt5Widgets.dll

•libgcc_s_dw2-1.dll

•libstdc++-6.dll

After that the graph_history_tool directory can be zipped and sent to customers. The start.bat is then not needed anymore and the graphHistoryTool.exe can be started directly.

The Graph History Tool comes with two language translations (English and German). If other languages are needed, there is a way to add them:

The language translation is done with the Qt Linguist application (see here). If you want to create a translation on your own, you have to install Qt on your PC (download here, make sure to install the Linguist application).

After installation open the Linguist application and open one of the existing translation files (the files with .ts suffix, e.g. graphhistorytool_English_en.ts). Now go to File -> Save As and choose a new name for the translation file (to show the language in the Settings menu of the Graph History Tool the language file needs to be called whatever_<NATIVE_LANGUGAGE_NAME>_<LANGUAGE_ACRONYM>.ts, e.g. for spanish: graphhistorytool_Spanish_es.ts). After that go to Edit -> Settings. In this dialog the target language can be chosen. Chose the language and Country/Region then press OK and save the file.

Now you can open all translation files and start the translation process for the new language.

When the translation is finished, a binary translation file has to be created from the ts file. Sadly Qt Linguist does not provide a GUI tool for this operation so you have to do this on the command line: Open a command line and navigate to the directory where the .ts files are stored. Now type lrelease *.ts. This will create the binary translation files (suffix .qm). Place all .qm files in the application directory. When you open the Graph History Tool now, the new application should be available under Settings -> Language.

If lrelease.exe is not in your search path, you have to call it with the complete path, e.g. C:\workspace\Qt5.4\5.4\mingw491_32\bin\lrelease.exe *.ts
