How to Use Graphing Calculator TI-84 Plus to Graph

Graphing calculators are often the only way to solve an equation -- not only equations but graphs too. In this post, we will talk about the graphs on Orion TI-84 Plus graphing calculators. 

You might think that it would be easy to graph an equation/function on a graphing calculator. However, easy as it is to read, the way functions are found and used is not always obvious. 

This guide discusses what you need to know about graphing equations and how to use the Orion Ti-84 Plus to Graph, but this information applies to all other variants of the Orion TI-84 as well. Calculators like the Orion TI-84 Plus and the Orion TI-84 Plus Silver Edition are within this calculator range. 

How to Use Graphing Calculator TI-84 Plus to Graph

The TI-84 calculator is useful not only for solving equations but also for graphing. The numerous graphical functions allow the user to enter up to six equations at once and see them in a graph.

This calculator can also zoom in or out of parts of the graph and measure the coordinates of a certain point on the graph. Graphing and measuring an equation using the TI-84 calculator only requires a few basic steps.

Setting Up a Scatter Plot 

The scatter plot can be set up by following the given steps.

Step 1

Two graphs are normally opened on the calculator computer. You're going to need to toggle off plot two. If several plots are turned on, make sure you close all of them but one. The scatter graph can only be built on one plot at a time. It is also necessary to close all other plots.

Step 2

Next, you need to wipe out any saved functions that you might have worked on before. You will do this by going to “Y1” on the keyboard and clicking the “CLEAR” button. On the right side of the calculator, you will see a clear button.

Pressing the clear button will delete any Y1 functions, and you can now enter fresh info.

Step 3

Now enter your data in the columns L1 and L2 by going to the stat edit box. When you've reached your equation, your scatter plot will be ready for you.

Step 4

You will use the zoom stat to display the scatter diagram. Zoom the scatter plot in a situation where the plot is simple enough to research and examine.

Consequently, here are the following steps you need to take in order to get access to graphs later on.

1. Finding the Draw Feature

Once the stats are turned off, you will need to find and enter the screen for the drawing feature.

2. Finding an Exemplary Equation

On the screen/list of your Orion Plus, you can conveniently find the “y=” button. On the display window, you will need to find some equation collections. Once you've found equation collections, start with "y=" as the exemplary equation. 

Many graphical calculators on the TI-84 Plus have a labeled button to separate the menu list with ease. With a brand new button, anyone can easily navigate the menu list. This also helps to locate “y=” as well. That is usually at the top of the calculator functions. 

3. Entering Your Personal Feature

The feature you want in your graph must be entered now. Note that part of the equation is already chosen by the calculator Y=. So now, the “y=” equation doesn't have to be stated, so the rest of the equation is in TI-84 Plus only.

4. Taking Vector

The remaining equations typically only consist of the variables. A graphical device with an "x" number is needed. Ax x and ax y are nonlinear graphs. Take the vector x and enter the equations of this variable.

For example, if a chart "y = x-3," "variable x," "-" and "3" is represented.

Entering Equations Before Graphing Them -- Simplified Step-By-Step Help

You will need to enter your equations into your calculator before you can graph them.

Before diving into the entire process of graphing, we’ll need to note intricate details about how to enter these.

Step 1

Click the [y=] button on your screen or the “Y=” button on TI-84 Plus.

Step 2

You'll see the screen displayed below. This is where you can enter all the calculations you’d like to graph. 

Y= Screen 

Step 3. Making Sure All Expressions Are Separated

Bear in mind that all of the calculations must have the expression “Y” separated on one page. For example, if we had an equation like “Y+4=X,” we will have to deduct 4 from both sides to get Y=X-4, so that we could type it as "X-4" in our calculator. 

You can graph up to ten equations at a time by typing them into one of the slots on the Y= pad. You will use the arrow keys to maneuver around.

Graphing the Equation

Now that you've entered your equations and expressions into the calculator, you’ll need to see what they look like.

When you've finished entering the calculations, press the [graph] button on the graph screen. As soon as this button is pushed, the calculator will work by drawing the equations on the graphics pad!

Changing Equations You've Already Entered

To change the equations you've entered, click the [y=] button again. 

Clearing Equations You've Entered

To clear the equations you entered press “y=,” scroll to the equation you want to erase, and then press the clear button. If you are unable to see the function you typed in, you may need to change the display window as stated in the next line.

Switch the viewing window from the graph screen.

Setting the Viewing Window

The easiest way to set up the viewing window is to use the “window” button on your calculator (right next to the “y=” button). 

Once you've opened it up, you'll be subject to various graphing functions.

Upon opening it, you'll see a few scary-looking numbers. Thankfully, you've got this tutorial to direct you.

What the Numbers Mean on Orion TI-84 Plus Talking Graphing Calculator

The following few terms are meant to help you visualize precisely what these numbers mean: 

Xmin and Xmax

These are the smallest and largest values displayed on the x-axis of the calculator. 

Ymin and Ymax

These are the smallest and largest values on the y-axis that the calculator can display. 

Xscl and Yscl

This is the distance between the tick points on the x-axis and the y-axis. 


This specifies the resolution of the graph. It can be set from 1 to 8 or to any integer. Simply put, the larger the number, the faster the graphics but the worse the output will be.

I've never changed this value in all my years of using these calculators, and I doubt you'll ever have to do so either.

Summarizing the Procedure of Graphing

Step 1

Click the "On" button at the bottom of the calculator. The calculator will automatically turn off if no one uses it for a few minutes. (To turn it off manually, press the "2nd" button at the right, followed by the "On" button.)

Step 2

Click the "Y=" button at the top of your calculator. The five buttons in the top row are all related to graphics.

Step 3

Enter the equation that you want to see graphed on the first "Y=" line. Enter additional calculations on the "Y=" section below the first line. Limit the equation to each side.

Step 4

Enter the letter vector by clicking the "Alpha" button, followed by the button that has the letter you want to be written in the right corner above it. For example, the variable "x" can be entered by pressing "Alpha" followed by "Sto>." 

Click the "Window" key and enter the values of the graph. This helps you to adjust the length of the X and Y axis as well as the number of values between the lines. 

Steps to See the Swing Equation Graphed

To see the equation(s) graphed, click the "Graph" tab. 

Click the "Zoom" button and select a number from the options column. They allow you to zoom in or out, and you will need to zoom into a particular point on the graph. 

Click the "Trace" button to shift a blinking cursor down the line(s) of the graph. The bottom of the panel displays the (X, Y) coordinates of the highlighted spot on the screen.

TraceStep and 𐤃X

This is another value that you may never modify or change. 

𐤃X is often considered to be the half of TraceStep, which specifies and signifies the movement of the cursor on the graphic screen when it's in trace mode. You can enter this mode by clicking the trance button of your calculator to watch the graph and see the dots that make it up.

TraceStroo monitors the C-Value Jump when you monitor the feature in the trace method. Contingent on if you want the easier alternative, you can always click the zoom button on your calculator.


How do you graph absolute value equations using a graphing calculator?

Your Graphing Calculator is an efficient graphing method for absolute value calculations.

Use the following steps to graph the Absolute Value Equations on your calculator:

If you enter “Y=,” you will be able to enter an absolute-value equation or an absolute-value function. Then just click the graph to see the graph of the equation on the screen.
