Introduction
In today's data-driven era, scientific research and data analysis are inseparable from efficient data processing and visualization tools. Traditional data processing software is often complex and requires a certain programming foundation, while web applications have gradually become a new choice for data analysis due to their convenience
2. Data normalization:
After the data analysis is completed, the program first finds the maximum value in the Y-axis data. Then, divide all Y values
2. Find the left and right boundaries - traverse the Y data starting from the left, find the first point greater than or equal to 0.5, and determine the left boundary position.
3. Traverse the Y data starting from the right side, find the first point greater than or equal to 0.5, and determine the right boundary position.
4. Calculate FWHM--FWHM is the X value corresponding to the right boundary minus the X value corresponding to the left boundary. This calculation method is simple and effective, and can quickly reflect the width characteristics of data peaks.
3. Calculation of FWHM:
The steps to calculate FWHM are as follows:
1. Determine the half-maximum value--Since the Y-axis data has been normalized, the half-maximum value is 0.5.
2. Find the left and right boundaries - traverse the Y data starting from the left, find the first point greater than or equal to 0.5, and determine the left boundary position.
3. Traverse the Y data starting from the right side, find the first point greater than or equal to 0.5, and determine the right boundary position.
4. Calculate FWHM--FWHM is the X value corresponding to the right boundary minus the X value corresponding to the left boundary.
This calculation method is simple and effective, and can quickly reflect the width characteristics of data peaks.
Usage:
Upload data file: The user clicks the file upload input box and selects the TXT file containing two-dimensional data.
Data processing and drawing: After the file is uploaded, the program automatically reads and parses the data, performs normalization processing, calculates FWHM, and draws a line chart.
View results: Users can visually see data trends in the drawing area and view FWHM values in the result display area.
Download chart: If you need to save the chart, the user can click the "Download Image" button to download the chart as a PNG image.
