2d interpolator

skyline plot similar to boxplot but with a continuous line

change even background between skyline and background?

Usage on e-Paper Displays (with GxEPD2)

I am trying to use your library with GxEPD2 as GFX driver.
Unfortunately, all I am getting is a white/gray screen, no graphs are drawn, nor anything else. Once your class is instantiated and the GFX object is passed to the constructor, all other text that had been on the display before, also disappears. In this case I am not sure if I understand the window parameter properly, eg. if I even should be able to supply my own text next to the graph or not, because I never got it working once.

Do you think you might be able to find out where the issue lies in this case?

add custom functions to parametric datasource

Create 'dotwork' plot object

More explanation on how to configure plots ?

Hi Marco,
the examples are pretty impressive ! I read and tried them all, also looked at the wiki and the source code.
The examples are a bit complex and some comments about which parameter does what would be great !
But still, I can't figure out simple things like

setting boundaries (i.e. if one only wants to use a part of the display for the diagram
how to adjust the rotation of the diagram to the screen rotation
how to make visible X/Y-axes with names and numbers
how to make bar graphs horizontally / vertically and how to set the colors
how to scale the axes
in dataset.begin(dataArray, 1 ,5), dataArry contains the data, 5 is for 5 elemets, but what is the "1" doing ?

Maybe you could add some explaining comments to the examples or the wiki ? That would be great !
Many thanks in davance !

scatter plot with rotation of marker (cross, line)

line marker could serve to produce field
rotation could come from opt
