This data is a 3D histogram.  It represents the Luma component (whitness) of the video. It is the same type of graph as for the [[Kdenlive/Manual/View Menu/RGB Parade|RGB Parade]]. The horizonal axis represents the horizonal axis in the video frame. The vertical axis is the pixel luma from 0 to 255. The brightness of the point on the graph represents the count of the number of pixels with this luma in this column of pixels in the video frame.

Waveform

This data is a 3D histogram. It represents the Luma component (whitness) of the video. It is the same type of graph as for the RGB Parade. The horizontal axis represents the horizontal axis in the video frame. The vertical axis is the pixel luma from 0 to 255. The brightness of the point on the graph represents the count of the number of pixels with this luma in this column of pixels in the video frame.
