while searching for solutions making textures in bar charts possible, I found this code posted by the user halmir here: Hatched bars and bar-specific background in BarChart
Unfortunately this doesn't work for low chart heights, which are smaller than the width of the chart. The term (yt - width) becomes negative and errors appear.
For example:
BarChart[{2, -1, .05, -3, 3, 2.5}, BarSpacing -> 2,
ChartElementFunction -> barFilled[.65, 3, 35], ChartStyle -> 61,
GridLines -> {None, Automatic}]
Is there another solution to change the appearance of barcharts? Already tried the approach How to change texture of chart bar? which uses the texture command and images. For big numbers and stacked bar charts it is noch efficient anymore.
If you know an easy approach for changing barcharts, my computer and I would be very thankful:)
Sorry for the huge text & all the best, Kilian
