That depends on the aplet. For the Statistics aplet, see section 10 of the manual. If you need a manual, you may download a copy at http://www.hp.com/ctg/Manual/c00751802.pdf
First - Are you graphing within the proper window? Hit the zoom button and change it to zoom Standard within the graphing window.
Second - Are you inputting the equation correctly? Make sure you are inputting your equations in a y= format. If possible, please reply with a screenshot of your graph screen.
Adjust the contrast. Turn the calculator on. Press and release the 2ND key, then press and hold the up-arrow key until the screen darkens. If you go too far, repeat the process with the 2ND and down-arrow keys.
Graph the function. You will see that it oscillates about the line y=1.5x-2.225, but it intersects the x-axis at only one point. You can use the HP solve application to approximate the solution. The solution is approximately x=1.31403145676
This error show up when you are graphing out of the plot menu. If you are not graphing data points from list menu, you need to turn the plots off. In the y= screen, you will see the words plot 1, plot 2, etc across the top of the screen. If one of the plots is highlighted (black box over the words), you need to turn it off. This can be done by arrowing up and highlighting the box and pressing enter. When you arrow back down, the plot should be off and you will be able to enter an equation in the y= lines and graph.
If you are graphing from the plot menu, this error lets you know that one of the lists you are graphing is longer than the other.
Another way to fix the problem is to reset the calculator by pressing 2nd button then plus sign then 7 then 1 then 2. This will reset the calculator however if you are graphing from lists, your data will be erased. Hope this helps.
