A trend line is a line added to a scatter plot that shows the generalization of all the data. Let's look at the scatter plot used in this explanation to show a trend line. Example: Trend Line on Scatter Plot We ask our friends their height and shoe size. The data is recorded below....
Scatter plot is a useful way to explore two variables relationship, but it also has a shortcome: we have to guess it's trend by our eyes. If we can add a trend line to the scatter plot, it will makes our opinion more clear and powerful. This step will benefit not only readers but...

Currently it's possible to have a trend line on a scatter chart, but if you add fields to Size and convert it into a bubble chart, the trend lins is no longer available. Is there a way to keep this trend line based on the x/y axis value even when using it as a bubble chart?

A trend line is a line that minimizes the distance between each point in a scatter plot and the line itself. There are positive trend lines (the values of the variables rise and fall together) and negative trend lines (the values of the variables move in opposite directions). Not all scat...

This option is useful when you know that you want your trend line to begin at zero. This option is available only when both the Rows shelf and the Columns shelf contain a continuous field, as with a scatterplot. Decide whether to show recalculated lines when you select or highlight data...
mat.plot(x,slope*x + intercept,color='blue') mat.show() In the above code: The “plt.scatter()” function is used to plot a scatter plot of “x” and “y” with red dots and the size of each dot as “50”. The “polyfit()” function fits a line through the scatter plot da...
