@@ -181,11 +181,38 @@ The size of the area to which the chart is plotted (the rest is taken up by
 ticks, labels and in future probably captions). The behaviour is undefined if
 C<< $.plot-width < $.width >> or C<< $.plot-height >>.
 
+Note that if you chose C<$.plot-width> or C<$.plot-height> too big in
+comparison to C<$.width> and C<$.height>, label texts and ticks might
+exceed the total size, and be either clipped to or drawn outside the canvas,
+depending on your SVG renderer.
+
+=head2 $.fill-width
+(Might be renamed to a more meaning name in future) For each bar in the bar
+chart a certain width is allocated, but only a ratio of C<$.fill-width>  is
+actually filled with a bar. Set to value between 0 and 1 to get spaces between
+your bars, or to 1 if you don't  want spaces.
+
+=head2 $.label-font-size
+Font size for the axis labels
+
+=head2 &.y-tick-step
+Closure which computes the step size in which ticks and labels on the y axis
+are drawn. It receives the maximal C<y> value as a single positional argument.
+
+=head2 $.max-x-labels
+Maximal number of plotted labels in C<x> direction. If you experience
+overlapping labels you might set this to a smaller value. The default is
+dependent on C<$.plot-width> and C<$.label-font-size>.
+
+=head2 $.label-spacing
+
+Distance between I<x> axis and labels. Also affects width of I<y> ticks and
+distance of labels and I<y> ticks.
