Step 1: Inspect and Copy Chart Data
- Right-click on the first chart (e.g., the line chart) and select Inspect.
- Expand the HTML/SVG element for the chart to locate the SVG path element containing the X and Y coordinates.
- Copy the SVG data representing the coordinates.
- Repeat the above steps for the second chart (e.g., brush chart).
Step 2: Extract Raw Coordinates
- Open a Text Editor (e.g., Notepad).
- Paste the copied SVG data for both charts into the text editor.
- Use the Search (Ctrl+F) function to locate and replace any non-coordinate data.
- Replace all unnecessary characters, so only the X and Y coordinates remain (separated by commas).
- Example:
M 10 20 L 30 40
should be transformed into just10,20
and30,40
.

Step 3: Import Coordinates into Google Sheets/Excel
- Open Google Sheets or Excel.
- Copy the raw X and Y coordinates for each chart from the text editor.
- Paste the coordinates for the first chart into one sheet and the coordinates for the second chart into another sheet.
- Label the columns appropriately (X and Y).

Step 4: Create Scatter Charts
- In Google Sheets or Excel, highlight the X and Y data for the first chart and insert a Scatter Chart.
- Repeat this process for the second chart’s data to create another Scatter Chart.
- Ensure that both charts have the same axis ranges and formatting (if necessary, adjust the scales).
Step 5: Export Charts to PowerPoint
- Copy the first Scatter Chart from Google Sheets or Excel.
- Open PowerPoint and paste the chart onto a slide.
- Repeat the process for the second Scatter Chart.
Step 6: Overlay the Charts
- Select the second chart in PowerPoint and make it transparent (reduce the opacity) using the formatting options.
- Position the transparent chart directly over the first chart.
- Use the arrow keys to adjust the positioning so that both charts are aligned perfectly.\
