| Color the dataset by the vtkBlockColors field. | |
| Retrieve the color map, opacity transfer function, and 2D transfer function for vtkBlockColors. | |
| Set block coloring for the block at /IOSS/element_blocks/block_2 using the x component of the ACCL variable. | |
| Rescale the block's color and opacity maps to match the current data range of block_2. | |
| For the ACCL variable of block_2, retrieve the color transfer function, enable the color bar, and apply cool to warm | |
