Hello, I have a probem with my bar plot. I group my data with the histc function (groups not evenly spread) and calculate the x and y average for every group with accumarray. In the next step I use the bar command to draw the groups. Now to my issue:

The bars are placed at the average x value and have the bar width 1 (figure) and between each bar is a gap and I dont want those gaps.

Every bar should have the width of his values range. So each bar must have a individual width. How can I do this? Or is there a way to create e.g. 10 groups with the same range?

The bar graph is pretty difficult to use as generic tool with extensive customizations unfortunately.

I'm guessing you may be better off to just draw patch objects with area or patch or perhaps a combination of stairs and fill or the like to draw the areas as you want where you want.

I don't think the multiple bar works as you would need to overlay as many single-bar plots as there are bar widths.
