Graphs: Improved Grid and labels

Lots of new stuff in OresmeKit, the graphing toolkit for GNUstep and Mac! As an Example, an advanced dashboard based on DataBasin that displays the system load of It is not generally available yet, but I hope it will be!

Grid-sizing is now selectable so it gets spaced in 1K or 1M intervals (depending on the data-range available), like it is used in both screenshots in this example.

 - (void)setYAxisGridSizing:(OKGridSizing)sizing;

Can take now: OKGridConstantSize, OKGridKiloMega

Also, one can decide to draw Just the label of the minimum and maximum value or a label for every grid:

- (void)setYAxisLabelStyle:(OKLabelStyle)style;

Can take:  OKNoLabels, OKMinMaxLabels, OKAllLabels

1000-unit Grid

To complement this kind of visualization, a new kind of Label formatting can be used. In the example above, the numbers are plain, 10.000 is written as such, in the example below, it is formatted as 10K, if we were using 10.000.000, it would me 10M

1000 - grid with K formatting
