Linear Regression Graph Creator

Input Data

Start by entering your data into the table on the left under the Input Data section. Each row should include:

Dependent Variable (Y-axis values)
Independent Variable (X-axis values)
Group (label for data points)

New rows will be added automatically as you fill in the data. You can also paste data directly from Excel, ensuring each row has three columns.

Customize Your Graph

After entering your data, click Update Data to generate the plot. Customize your plot using the options in the right sidebar:

X/Y Axis Labels: Set custom labels for the axes.
Font: Choose the font style and size for labels and axis text.
Group Symbol: Select symbols (dot, plus, or x) to represent different data groups.
Axis Adjustments: Manually set the start and end points for the X and Y axes, or use the auto-adjust feature.
Graph Dimensions: Modify the width and height of the graph, along with the thickness of axes and regression lines.

Exporting Your Plot

Once satisfied with your plot, you can export it using the options available under the Export tab:

Export Format: Choose from JPEG, PNG, TIFF, or BMP.
Resolution: Select the desired resolution (300, 600, or 1200 ppi).
File Name: Specify a custom filename before exporting.

Click Export Plot to save the plot to your computer.
