Plotting

Plots
Plots can be created inside a worksheet via "Add new" in the context menu or in the application menu via "Worksheet" by selecting "xy-plot" and the type of plot you like to have.
Within this xy-plot you can add a xy-curve containing data to show (again via the context menu or application menu).
The settings of a plot can be changed in the corresponding dock widget. There are general settings like geometry but also the range of the x- and y-axis (including scaling). The plot title can be set in the "Title" tab of the dock widget. Background and border styles can be changed in the "Plot Area" tab.

Curves
Curves contain data points that can be shown in a plot. There are three different method to create curves: the standard xy-curve, a xy-curve from a mathematical expression and a xy-curve from a data analysis function.
The standard xy-curve can be filled with values of a spreadsheet by selecting the x-data and y-data as column of the spreadsheet in the xy-curve dock widget. Another method to fill a curve is to use a mathematical expression. Here you can select any mathematical function and range to create the curve. The third method to create a curve is to use a data analysis function. The data and the analysis function can be selected in the dock widget of the analysis function.
For all types of curves the line and symbols styles can be changed in the dock widget. Also annotated values and error bar settings can be changed here.

Legends
A legend can be easily added to a plot by using the context of application menu. It contains information about all curves in a plot.
The settings of a legend (format and geometry) can be changed in the legend dock widget. Also the legend title settings, the legend background and the layout can be changed in the corresponding tab of the legend dock widget.
