I have some lines on x-y plane in order to divide and distinguish a region. The scale difference between x and y axis is very large. And I have also some points including z data. Z data does NOT depend on lines. I want to represent z data with colored bar on x-y plane. The bar can have a different shape. I tried to this with 'scatterbar3' and 'bar3' function but failed.
The figure below shows the example what I want to make. How can I make it??
