The word "innermost" in this case refers to the table structure. If these shelves containīoth dimensions and measures, Tableau places the measuresĪs the innermost fields, which means that measures are always to the right of any dimensions that you have also placed on these shelves. It looks like the regression line doesn't fit on this data and there is not a strong correlation and some outliers.Use scatter plots to visualize relationshipsīy placing at least one measure on the Columns shelf andĪt least one measure on the Rows shelf. customize the plot, label the title, x-axis, y-axis, total vaccinations, and legend.Plot the regression line, make the line read and label it regression line.This code uses NumPy to take the coefficients previously obtained, and evaluate the coefficients to define a mathematical expression, representing the line of best fit.use polynomial fitting from NumPy to fit a polynomial degree of 1 to the data points in New Deaths and Total vaccinations.create a scatterplot using matplot, with the x-axis as the merged on new deaths, and the y as the merged column of total vaccinations, with the marker size as 50.Merge datasets on the common date column - inner merge so rows with non-matching values will be excluded.Same thing but for the vaccination-data. ![]() converts the values in the 'Date_reported' column from string representations of dates to actual datetime objects
