Chapter 8. Examples

In this chapter you will find explainations of the example projects of LabPlot. You can find all the examples under Help->Examples except specified

Table 8.1. Example Projects for LabPlot

ScreenshotNameDescription


axes labelthis example shows how to use different axes label. The shown function is filled to the baseline.


rydberg spectrathis example shows a Rydberg spectra measured by photoexcitation of metastable helium in a magneto optical trap.


log axis scalethis example uses logarithmic axis scales with custom tic label


audio datathis example shows data read from an audio file


analysisthis example shows the difference between the three analysis functions prune, average and smooth. Here you can see different styles and symbols for showing data.


simple fftthis example shows how a simple fourier transform might look like.


histogramthis example shows a sample histogram of a periodic function.


nonlinear fittingthis example shows a nonlinear lorentzian fit of a sample data set in a specified region.


exponential fitthis example shows how an exponential fit of sample data should look like.


surfacethis example shows a simple surface plot with density and contour plot of a used defined function. The color palette is choosen to nicely show the function values.


3dthis example shows a simple 3 dimensional plot created from a function.


drawing objectsthis example shows how to use drawing objects in LabPlot.


imagesthis example shows a surface plot created from an image file (utm.xpm).


pie plotthis example shows a simple pie plot created from two dimensional data


multiple plotsthis example shows the usage of multiple plots per worksheet. Here you can s see four different types of plot arranged 2x2 with gap=0.05.


qwt 3d plotthis example shows the usage of a qwt 3 dimensional plot. This example uses a customized colormap and the "flooriso" style to make the contour lines on the floor.


GRASS plotthis example shows how LabPlot uses the GRASSQt interfce to display different layers as GRASS plot. Although it might look nice, the capabilities for GRASS plots are very limited at the moment.


another surface plotthis is another example for a surface plot. This example shows how logarithmic axis scals can be used her too.


polar plotthis example shows a simple polar plot created from functions


ternary plotthis example shows a ternary plot created with some data


sfi (only on download site)this example introduces overlayed plots by showing a selective field ionization spectra overlayed with the field ramp.
