#LINE PLOT ON MINITAB EXPRESS CODE#
The following code (hopefully) shows some "good practise" and some of the capabilities of matplotlib to create the plot you mention in your question. Get deals on Minitab 19, Minitab Express, and Minitab. However, you are asking for "good practice". Buy Minitab for as low as 29.99 from OnTheHub, your source for student & faculty discounts. about the regression use: menu Stat Regression Fitted Line Plot. Plottakes either y values and uses x as index array 0.N-1 or x and y values as described in the documentation. The image you show is a probability plot of a single variable, not a regression. YText = t_ylabel('TPR / Sensitivity')īins = np.arange(-lim, lim + binwidth, binwidth)Įverything works, except the p5 which is a line. Lim = ( int(xymax/binwidth) + 1) * binwidth Plt.legend(,, names, names, names, "Random guess"], loc = 2) P4 = axScatter.scatter(x, y, c='yellow', s = 70) P3 = axScatter.scatter(x, y, c='red', s = 70) P2 = axScatter.scatter(x, y, c='green', s = 70) P1 = axScatter.scatter(x, y, c='blue', s = 70) Minitab offers several resources that are helpful for you. Learn to plot different types of charts in Minitab. Since Ppk is the lesser of these two values, the Ppk is 0.80.

You can get a license for 6 or 12 months. Learn more about Scatter Plots in Green Belt Training. The strength of correlation on a Scatter Plot can be measured using a Correlation Coefficient. My code is based upon a simple scatter plot from the gallery: # definitions for the axes The Calculator has many predefined functions. A Scatter Plot is also known as an XY Plot since the variables are plotted on the X and Y axis. And frankly, the documentation-examples-gallery combo and content of matplotlib is a bad source for information. So, I have a few (4) points and I want to add a line to it, like in this plot (source: ) I just want to analyse my scatter plot with a few graphical features.įor starters, I want to add simply a line. I can't believe that this is so complicated but I tried and googled for a while now.
