I want to plot a 3d bar chart like in this example but I can not or dont know how to use the code for my data. This is how my data looks like:
z = np.array([[ -10., -40., 0., 20., 10., 0., 0., 0.],
[ 0., -50., -60., -20., 20., 0., 0., 0.],
[ -60., -140., -90., -20., 20., 0., 0., 0.],
[ 190., -70., -240., 20., 20., 0., 0., 0.],
[ 430., 70., -380., -20., 20., 0., 0., 0.],
[ 170., 0., -280., -110., 20., 0., 0., 0.],
[ 20., 10., -90., -80., 20., 0., 0., 0.],
[ 20., 20., 20., 20., 20., 0., 0., 0.]])
This is how it shoud look like but with my data and a grid of 8x8:
My z-values represent the height/depth of the bins. So in total I would have 8x8 bins on this 3D plot.
I want to use Plotly because the plot will be embedded in Plotly Dash and should be interactive. So how do I need to change my data fromat to use the code from this example or is there another possibility to get such a plot in plotly?
