### Date Axis
|
||||
This project (see `./test/simpletest_dateaxes/`) simply creates a JKQtPlotter widget (as a new window) with the X-axis showing time or date(-time) values, formated as such.
|
||||
|
||||
The source code of the main application can be found in [`jkqtplotter_simpletest_dateaxes.cpp´]((https://github.com/jkriege2/JKQtPlotter/blob/master/test/simpletest_dateaxes/jkqtplotter_simpletest_dateaxes.cpp).

|
||||
|
||||
First some data is parsed from a CSV-file (added as ressource to the example). Note that the Time/date or Date+Time data is internally stored as milliseconds since epoc (Jan 1st 1970, 00:00:00), therefore data has to be converted accordingly before beeing added to the graph.

## Different Types of Errorindicators
|
||||
This project (see `./test/simpletest_errorbarstyles/`) simply creates a JKQtPlotter widget (as a new window) and adds several curves show-casing different styles of error indicators. Data is initialized from two QVector<double> objects.

First some data is added to the internal datastore (mostly, like explained in several other examples, like e.g. [Line Graph with Different Symbols and Line Styles](https://github.com/jkriege2/JKQtPlotter/tree/master/test/simpletest_symbols_and_styles)). The (in a loop) several graphs are added, each with a distinct style for its error indicators:
