To enter a data set, use the x and y columns in the data table. For example, to enter the point (6, 12), enter 6 into the x column and 12 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. Other types of data must be represented by numbers before they are entered.
For example, suppose a poll shows that 12 people own birds, 23 own cats, and 20 own dogs. Use the numbers 1, 2, and 3 could represent "Birds," "Cats," and "Dogs." The data set is (1, 12), (2, 23), and (3, 20).
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 a bar graph of the data.
The calculator displays the minimum and maximum values on each axis and distances between the tick marks.
To change the set, click the drop-down arrow and choose the other data set. Then click Draw.
To change the minimum and maximum values on the y-axis 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.
