Scatter Plots

Add a table to your expression list to start plotting points.

 

Next, fill in the table cells:

 

Note that you can have multiple scatter-plot columns in the same table:

 

If a table heading is a function, we'll fill in all of the values for you. One special case: a column heading can reference any of the previous column headings in your table. For example, if you have an "x" column, a "y" column, and an "x+y" column, we'll fill in the x+y column based on the first two columns:

 

You can long-hold the icon next to a scatterplot to see various options, including the ability to connect the points, to hide the points, to drag the points, and change the color:

 

Now that you have a scatterplot, how about finding a line of best fit? Learn more about regressions in Desmos.

    Regressions are now supported! Try the regressions tour in the help menu ( ? ).

    Can someone help me figure out how to make a similar table of values like this for polar coordinates of the form (r, theta)? I've changed the graph settings to "polar" but I get a message that says I cannot have the first column be "y, r, or theta".

    I think I can do it using x = rcos(theta) and y = rsin(theta) and it plots them just fine on the polar grid using the x and y columns of the data table. I don't see any way to make a table with r and theta as the columns though.

    Is there a way to do histograms and box-and-whisker plots? Am currently teaching Data Management and it would be helpful if students could complete all graphing requirements using one program.

    How do you find out the line of best fit and it's equation?
