Can I graph multiple lists at the same time?

Yes, the TI-84 Plus allows multiple STAT PLOTS. Assign different Xlist and Ylist pairs to Plot1, Plot2, and Plot3, and use different markers or colors for distinction.

What should I do if my scatter plot looks empty?

Check that your Xlist and Ylist have matching data lengths. Also, ensure your WINDOW settings or use ZoomStat to auto-scale the graph to your data range.

How do I change the marker style for points?

Press 2ND → Y=, select your plot, and under Mark choose a shape (square, X, dot, triangle) for your points.

Can I graph a list without entering formulas?

Yes. You only need to input your data into lists (L1, L2, etc.) and use STAT PLOT. No equations are required for plotting lists.

How do I add a trendline to my graph?

Use STAT → CALC to choose a regression type (linear, quadratic, etc.) and overlay the equation on your scatter plot for trend analysis.

Is it possible to graph lists with negative values?

Yes. Ensure your WINDOW settings include negative ranges for Xmin and/or Ymin, so all points appear within the graph frame.

Why does my graph look squished or stretched?

This usually happens if your Xscale and Yscale are very different. Adjust the scales or use ZoomStat for proportional visualization.

Can I save my graphs for later reference?

The TI-84 Plus does not save plots as images, but you can leave the lists and plots stored in memory. Re-graphing will recreate the plot.

📊 How to Graph a List on TI-84 Plus (Beginner-Friendly Guide)

Graphing a list on the TI-84 Plus is a fast and effective way to visualize relationships between variables. Whether you’re analyzing homework, preparing for an exam, or exploring trends, your TI-84 makes it easy to transform raw data into clear graphs.

In this guide, we’ll walk through every step: entering data, setting up STAT PLOTS, adjusting the window, and analyzing the graph, so even beginners can follow along.

Step 1: Enter Your Data into Lists

Press STAT → 1:Edit. Input your x-values in L1 and y-values in L2. Use additional lists for extra datasets. Make sure each list has the same number of entries for proper graphing.

L1 (X)	L2 (Y)
1	2
2	4
3	6
4	8

Step 2: Choose a Graph Type

Your TI-84 Plus supports:

Scatter Plot – shows individual points for each x-y pair.
Line Plot – connects points to highlight trends.
Histogram / Box Plot – useful for single-list distribution analysis.

Scatter plots are most commonly used for graphing lists with x-y data.

Step 3: Turn On a Stat Plot

Press 2ND → Y= to access STAT PLOT. Select 1:Plot1 and press ENTER. Turn the plot ON, choose the type (scatter/line), set Xlist = L1 and Ylist = L2, and select a marker style.

Step 4: Adjust the Window

Use WINDOW settings to control the visible range:

Xmin / Xmax – range of x-values displayed
Ymin / Ymax – range of y-values displayed
Xscale / Yscale – tick mark intervals

If points don’t appear, use ZOOM → 9:ZoomStat to auto-scale the window.

Step 5: Graph Your List

Press GRAPH to see your points plotted. Adjust the window manually or use ZoomStat for proper scaling. Verify your lists have matching entries for accurate visualization.

Step 6: Analyze Your Graph

With your graph visible, you can:

Identify patterns: linear, quadratic, exponential
Detect outliers
Use STAT → CALC to fit regression models
Compare multiple datasets using additional plots (Plot2, Plot3)

Step 7: Bonus Tips

Clear old lists before entering new data.
Use distinct markers/colors for multiple plots.
Try ZoomStat to auto-fit your graph.
Experiment with regression trendlines for deeper analysis.
Practice graphing different datasets to gain confidence.
