I have a dataset in a 8261x4 matrix where the first 3 columns represent x,y,z coordinate and the fourth column vlaues are ones as in the figure below:
thses are sunrays hitting a rectangular surface. the ones represent the power per ray. I want to generate a surface like in the next figure (it is a 2d plot using x&z only):
in the previous figure, the surface devidied by 25x25 (resolution) and the ones in the fourth column in the matrix were summed based on the grid resolution.
I include the y-axis because I have another data for tilted surfaces (3D), the end goal is to plot the flux map on multiple panels (shown in the figure below) and each panel will have a data like the martix I showed previously.
