The jagged line that is inserted on the x-axis is used to represent this fact. The frequency polygon also shows the shape of the distribution of the data, and in this case, it resembles a bell curve. Probability Histogram. How to smooth my density line? However, in some cases, the anti-aliasing turns off during export. (TABLE CAN'T COPY). Covid-19 has led the world to go through a phenomenal transition . This histogram is used as part of a sequential (online) classifier that propagates samples down a classification tree using a test to decide whether the sample belongs in the left or right sub-tree. %matplotlib inline Introduction Of … Also, did you really mean to go from 0 to 2 and then increase by 1 for the variable names? For instance, important features like lines and curves can be extracted using edge detection, which are then normally used by higher-level computer vision or image processing algorithms. These two factors combined produce jagged looking histogram. Use it to help improve exposure. 1. Use the histogram shown. With too small a bin size, you get a jagged histogram. When you have a histogram plot, if you perform a nonlinear curve fit on the data, what you end up fitting is the raw data and not the binned data. – G5W Mar 27 '17 at 17:07. When something clips in a histogram, it means that data is lost in the photograph and what displays instead is either pure white or pure black.
