To enter a data set, use the x and y columns in the data table. For example, to enter the point (1, 67), enter 1 into the x column and 67 into the same row in the y1 column.
The arrow and tab keys can make data entry more convenient.
If a data set has more than 10 values, use the scroll bar to see all the values.
Clicking the Clear button erases all values in the table.
Note: The table only accepts numbers. For example, the value "January" can be represented by the number 1, "February" by 2, and so on.
Note: If an x-value has a value for y1 but not for y2, leave the y2 list empty for that x-value (and vice-versa).
Click Draw to draw the line graph(s) of the data.
The calculator displays the minimum and maximum values on each axis and distances between the tick marks.
To change the minimum and maximum values or the distance between tick marks, enter new values.
Note: Changes to data sets or axis settings do not take effect until
Draw is clicked.
