    I know its going to generate data from the function I make but that was a solution given to me. What I want to do is make a graph by entering my own X and Y values. But the Y table is non existant unless I create a function for it.

  • motoko_23 Oct 07, 2009

    so how do I get the Y table to work without making a function for it?

  • motoko_23 Oct 07, 2009

    I did read it and I did try it but it isnt going to bring back my "Y" table. What you said didnt apply to my situation.

    I'm using coordinates (9,0) etc to plot a parabola, I have to enter my X data values in one column and my Y data vlaues in another, But I cannot do so without creating a function for the Y table and when I do that I can't submit my own values.

    I used to be able to submit my own values in the Y table but I can't now for some reason. Someone on here had the same problem but it wasnt answered...

  • motoko_23 Oct 07, 2009

    I meant to say a scatter plot instead of a prabola. Don't get upset, I think I was justified in rating the current solution as Not helpful.Calling it worthless is a little harsh.

    But that was probably due to the fact I wasnt very clear....TT_TT sorry

  • motoko_23 Oct 07, 2009

    I dunno if this will help but my problem looks like this if you click on the link and scroll down to the third page where it says : The Y values are missing from the table...

It is noranl that you cannot enter data in the table becuase it was generated from the function you entered. If you specify the function you cannot specify the data in the table. But if you want to enter you own values, that is doing statistics, not graphing functions.
To do stats
Press STAT button, then select 5: SetUPEditor ENTER ENTER. You do that to reset calculator to do stats.
After that press STAT again, and select 1:Edit. The lists open to you and you can enter your data in the lists

But not knowing what you really want to do, I cannot advise you better.
Hope it helps.

    Do you actually read what people take time to write. The way to enter YOUR values in a table is to create a statistical table. That is the name for it. Once you enter the data such as in a census, you analyse them to find meanings, make predictions. I gave you the instructions to create the data table. Check other threads. Look for standard deviation, best fit, statistical graphs, histograms.

    Before you rate a solution as worthless, you should try it first. If you don't understand what we say, just ask for further clarifications.

    Here I am going to enter the values for a curve. Actual values will be shown on the lists L1 and L2. You create the lists as I described before [STAT][1:Edit][ENTER]. Lists open and I start x= 1, 2, 3, 4, 5, 6,7,8,9,10. Y=1, 4, 9, 26, 25, 36,49,64, 81, 100. As you see these values are made up to make the curve look like a parabola. y=x^2. When you do it you enter your own values. Ok.

    Then You press [2nd][STATPLOT] you scroll down to [4:PlotsOff] [ENTER] to clear any configuration that may give you errors.

    Press 4 and [ENTER]. The screen shows PlotsOff. You press ENTER and the screen will look like this

    Then you press [2nd][STATPLOT] Select Plot1 and [ENTER] . The cursor will blink on ON. Press ENTER to validate. Move cursor to TYPE . The first icon is that of a scatter plot. Reproduce what is on the screen that follows. L1 contains your Xvalues, and L2 your Y values.

    Press [GRAPH] That is what you see. Not much.

    To see more of the graph I change the Window setting by pressing [ZOOM].

    I scroll down till I see [9:ZoomStat] . and press [Enter]
    Here is now what I see.

    Now you can press [STAT] then select CALC. Select 5:QuadReg quadratic regression (a parabola), because I know it is a parabola I created it on purpose.

    I select 5 and press ENTER. The calculator tries to fit the data to a parabola and gives the equation. Here it is. The fit is perfect, because I chose the values.

    I artificially created statistical data to show you how to do a scatter plot. I chose the form of a parabola, because you wanted one. In real life you enter the values you got or measured, an so on, draw a scatter plot, look at the curve and try to guess : This is a straight line, this one a parabola, this reminds me of an exponential. After that you try the different models, till you find th so-called best fit.

Have the equation in the Y= then if you cant put info into the X column, go to TblSet (2nd Window) then where it said Indpnt, set it to ASK.

My TI-84 will graph but it will not show me the table of values. It just shows up blank.

Enter the function using the Y= editor. Pressing [ 2nd ][Graph] (table) will display the table. You can then press [GRAPH] to see the grapg. If you want both graph and table side by side use the split screen feature.
To do so press [Mode]. Scroll down to the last line Full Horiz G-T. Highlight the option G-T. Press the Graph key.

I am trying to graph a least-squares line on my TI-84 Plus. I have the numbers correctly plugged into my Stat Edit tables, and I am able to access my linear equation, and the first time I entered my graph...

After you enter the data draw the SCATTER plot first.
When you perform the (linear) regression analysis LineReg, save the regression equation to a function, for example Y1
The syntax is
LineReg L1, L2, Y1 ENTER

From the Stat>CALC menu press LineReg
The command echoes on command line
Press [2nd][1] to enter the L1 list on command line
Press [,] to separate
Press [2nd] [2] to enter L2 on the command line
Press [,] the comma again
Press [VARS][>][Y-Vars][1~Function][1:Y1] [ENTER]
Press [GRAPH] to have the regression line equation drawn
on the same screen as the Scatter Plot you drew before.

I need to know how to get to Table Set on the TI-85 because I need to find the x intercepts on the graph, but I can't find it. How do I get to it?

try this one:

(first). Set up a function in the TI85. how?
Step 1. Press the [Y=] key to open the function editor.
Step 2. Type in the function you want in the Y1= line.
Step 3. Press [2nd] [QUIT].

(second). Create a table of numbers using the Y1 function.
Step 1. Press [2nd] [TBLSET] to open the table setup menu. On the line "Indpnt", highlight "Ask" and press enter. On the line "Depend", highlight "Auto" and press enter.
Step 2. Now press [2nd] [TABLE] , type in a value for "X", and press [ENTER].
Step 3. Continue typing more values for X to fill up the table.

(third). How can I see more decimal places for the numbers in a table?
Step 1. Use the arrow keys to move the highlight over the number you are interested in seeing to more decimal places.
Step 2. Read the number at the bottom of the screen. You should be able to see anywhere from 9 to 14 significant figures for your number.

(fourth). Delete the numbers in a table by:

(The following procedure will work when the table setup has been set to ask for the values of the independent variable.)
Step 1. In the table screen, check the bottom of the screen to make sure that the cursor is not blinking at the bottom of the screen. If the cursor is blinking, press the [ENTER] key to stop the cursor from blinking.
Step 2. Use the arrow keys to move the highlight to the first number in the first column of the table (the "X" column).
Step 3. Press and hold the [DEL] key to delete the numbers in the first column of the table. The entire table should become clear with this procedure.

Thanks! I wish it can help you..

When you graph a function,where can I find the table??

I find it easier to generate the table then look at the graph. Here how you go about it, illustrated with screen capture taken from the newer version of the calculator. k24674_7.jpg
Press the MENU button.
Use arrows to highlight the TABLE application (1st screen).
Enter a function expression in Y1=
And press the function key F6 under the TABL menu tab. (2nd screen)
A table is generated (3rd screen)
Press F5 (G-CON) for a connected graph, or F6 (G-PLT) for a dotted graph.
The graph is shown (4th screen).
Use the Zoom function (ZoomAuto) or any other Zoom or change the window dimensions to suit your needs.

Hi, I can edit my table information in my calculator but am not able to graph from it and when i go to table it shows nothing.. what do i do?

From what I understand you want to draw statistical graphs (scatter plot, box plot, etc.) If you do not see anything it may be due to the fact that the statistical plots are turned off.

Type in the data in lists L1 and L2, etc. Press [2nd][QUIT]

Press [2nd][Y=] (STAT PLOT] . Select [4:PlotsOff] [ENTER] .
Screen displays Done

Press [2nd][Y=] (STAT PLOT] . Select [1:Plot1 Off].
  1. The configuration screen for Plot1 opens with the cursor blinking ON.
  2. Press [ENTER] to turn Plot1 ON.
  3. Use Down Arrow to move cursor to second line Type:
  4. Select the type of statistical plot. Use the right arrow to move highlight on one of the 6 types.
  5. Select the type:scatter, Xline, histogram, box plot, and press [ENTER] to validate the choisce.
  6. Use down arrow to select the Xlist: use [2nd][1] to choose L1, etc. and press [ENTER]
  7. Select the Y-List (L2) and validate by pressing [ENTER]
  8. Select the data-point mark.
  9. Press [GRAPH].
If you do not see the graph or if it is not well centred, press [ZOOM][9:ZoomStat] to restrict the screen to the data entered.

Hope it helps.
Thank you for rating the solution.

Help me please

Sorry if you already know that, but I want to make sure we understand one another.

Say you want to graph the function Y1=2X+3.
You press [MODE] to make sure that the FUNC on 4th line is highlighted permanently. If it is you press [Y=]

On the first line where it says Y1= you enter 2*[X,T,Theta,n] +3.
The X is accessed with the key to the right of the [ALPHA] key.
As you key in your function, notice that the equal sign after Y1 is highlighted and remains so. When you finish entering the function press [ENTER] so that the cursor moves to the line Y2=. Make sure that the = sign after the Y1 in previous equation remains highlighted.

You can now draw the graph by pressing [GRAPH] or generate the table Y1=f(X) by pressing [2nd][TABLE]. Under no conditions should you enter YOUR own values. If the table does not appear there may be a problem, and you will not solve it by entering values.

Now let us try to get you calculator to work as it should.

Press [2nd][STATPLOT][4:PlotsOff] , the command PlotsOff echoes on main screen. Press [ENTER] to turn statistical plots OFF. Screen displays Done.
Press [2nd][CATALOG] [ENTER]. The list of all avilable command appears. Scroll down till you reach ClrAllLists. Move arrow to the correspondig line and press [ENTER] , command echoes on main screen as ClrAllLists. Press [ENTER] to erase all old statistical lists that may be stored in the calculator memory.

Now you are ready to graph or create the table of values. Press [2nd][Table] and the table should be displayed. All you can do with the values in the table is to look at them, examine them. You cannot modifie nor erase them.

If, for reasons of your own, you think you ought to be allowed to enter YOUR values, in the table, then this is not graphing functions. The name for that is DOING STATISTICS. And the procedure is tottaly different: You enter YOUR values in lists and use the calculator to draw the data points, and to find the best fit (the curve that models the pattern of data distribution best). When you decide which fit is the best, you can use the calculator to extract the equation for the curve and, if you want it, to draw the curve on the same graph where you raw data is represented.
Hope these clarifications helps.
