When plotting or publishing from AutoCAD, lineweights and/or linetypes do not output correctly. The following may apply: Lines are inconsistent, such that they show the wrong size, either too thick or too thin. Lines vary from one end of a line to another. Dashed lines in the drawing may plot out as a solid/continuous line. The correct plot style has not been selected. Lineweights applied are. I tried subclass the 'backtrader.plot.Plot' but still not working. If you really want to use spyder, here is the trick: import backtrader.plot import matplotlib matplotlib.use('QT5Agg') # Your running code cerebro.plot(iplot= False) Remember to select your Graphic backend to 'Qt5' in spyder. I also had the issue on running my old code ploting figures on loop using hold on, earlier it was working fine in MATLAB2008 and MATLAB2011 but it wasn't showing plot while running the same code in MATLAB2015. Now adding the command drawline its working fine. Don't know the exact reason why. Still thank you!

If we wish to compare the data present within categories, box plots come into play. It is a way in which the data distribution in the dataset can be understood with the help of quartiles. It consists of vertical lines that extend from the boxes. These extensions are known as whiskers. These whiskers tells about how the data varies outside the upper and lower quartiles. This is why box plots are also known as whisker plots. Outliers in the data are plotted as individual points.

Violin plot is a combination of box plot with kernel density estimates (KDE). It is easier to analyse and understand how the data has been distributed. The wide portion of the violin indicates the higher density of data. The narrow portion of the violin indicates the lower density of data.

The inter-quartile range within a boxplot and the higher density portion of data fall within the same region in every category.

  • The required packages are imported.
  • The input data is ‘iris_data’ which is loaded from the scikit learn library.
  • This data is stored in a dataframe.
  • The ‘load_dataset’ function is used to load the iris data.
  • This data is visualized using the ‘violinplot’ function.
  • Here, the dataframe is supplied as parameter.
  • Also, the x and y values are specified.
  • This data is displayed on the console.
