Web Digitizer Tool Functionality

The video tutorial explains how to extract data points from published plots using the open-source tool Web Digitizer. It covers both manual and automatic data extraction methods, including handling plots with logarithmic axes. The tutorial provides step-by-step instructions on using the software, adjusting data points, and saving the extracted data in various formats.

Why might someone need to extract data from published plots?

• To learn how to use plotting software

• To compare their data with others when original datasets are unavailable

• To create new plots from scratch

• To verify the accuracy of the published plots

What is the first step in using the Web Digitizer tool?

• Adjust the view of the main image

• Download the software

• Take a screenshot of the plot

• Load a previous project

How do you identify the plot axes in Web Digitizer?

• By selecting the axis from a dropdown menu

• By adding four points to define the axes

• By entering the axis labels

• By drawing the axes manually

What is the purpose of the 'Add Point' mode in manual extraction?

• To save the extracted data

• To automatically detect points

• To manually place points on the plot

• To adjust the view of the plot

How can you adjust the placement of points in Web Digitizer?

• By entering coordinates manually

• By using the arrow keys

• By selecting 'Auto Adjust' from the menu

• By using the mouse to drag them

What is the advantage of using automatic extraction for solid lines?

• It is the only method available for solid lines

• It provides a detailed view of each point

• It allows for manual adjustment of each point

• It is faster and more accurate for continuous lines

How can you limit the search space for automatic extraction?

• By using the 'Limit Search' button

• By adjusting the plot size

• By drawing a mask on the plot

• By selecting a specific color

What should you do if some points are incorrectly placed during automatic extraction?

• Use the 'Delete Point' function to remove them

• Adjust the plot settings

• Ignore them and proceed

• Restart the extraction process

How do you handle plots with logarithmic axes in Web Digitizer?

• By ignoring the log scale

• By manually adjusting each point

• By indicating the log scale in the settings

• By converting the plot to a linear scale

What is a crucial step to remember before reloading the Web Digitizer page?

• Delete all previous data points

• Adjust the plot size

• Save the project to avoid losing data

• Change the language settings
