Without more information, like the fdf file you have used to calculate it,
it becomes a guessing exercise. However, if you are using one of the latest
versions of siesta, check if the PDOS.kgrid_Monkhorst_Pack is present. If
yes, then include a block PDOS.kgrid_Monkhorst_Pack with a grid at least
three times as dense as the one you have used for the SCF/relaxation, and go
increasing the density of the grid until you are satisfied with the final
graph.
