## Introduction

Matplotlib is a popular data visualization library for Python that allows users to create high-quality visualizations of their data. However, one issue that many users face when creating graphs using Matplotlib is the display of offset values instead of actual absolute values on the Y-axis. In this article, we will guide you through the steps on how to display Matplotlib Yaxis range using absolute values, removing the confusion caused by offset values.

## The Problem with Offset Values

Offset values can be confusing and can lead to difficulty in reading plotted data, especially when working with large numbers. Many users struggle with this problem, as it can result in an inaccurate representation of the data. When plotting graphs that represent time-series data, offset values can make it challenging to compare trends over time accurately.

## Why Use Absolute Values?

Absolute values offer the most accurate representation of the data, allowing you to make informed decisions based on the exact values rather than estimated or rounded numbers. In addition, absolute values are easier to read and understand, making it simpler to compare data across different time periods or variables.

## How to Display Matplotlib Yaxis Range Using Absolute Values?

The process of displaying Matplotlib Yaxis range using absolute values can seem daunting at first, but it is relatively simple. Firstly, determine the range of your dataset and set the Y-axis’s limits using the `set_ylim()` method. Next, use the `FuncFormatter()` method to convert the offsets into absolute values by defining a custom function that returns the absolute Y-axis value. Finally, apply this custom function to the Y-axis using the `set_major_formatter()` method.

## Implementation Steps

The following steps outline how to modify your graph to use absolute Y-axis values

1. Determine the range of your dataset
2. Set the Y-axis limits using the `set_ylim()` method
3. Create a custom function that returns the absolute Y-axis value
4. Apply this custom function to the Y-axis using the `set_major_formatter()` method.

## Code Example

Here’s a code example demonstrating how to use the described process:

### Inital Setup

``import matplotlib.pyplot as pltfrom matplotlib.ticker import FuncFormatterimport numpy as np# Create a data setdata = np.arange(10, 20)# Create the figure and axis objectsfig, ax = plt.subplots()# Plot the dataax.plot(data)# Set Y-axis limitsax.set_ylim(0, 20)``

### Custom Formatter

``def absolute_values(x, pos):        Convert the offset into an absolute Y-axis value        return '{:.0f}'.format(x)# Apply the custom formatter to Y-axisformatter = FuncFormatter(absolute_values)ax.yaxis.set_major_formatter(formatter)``

## Conclusion

The problem with offset values can be frustrating, especially when working with large datasets or time-series data. However, displaying Matplotlib Yaxis range using absolute values offers a simple solution to this issue. By following our guide, you can customize your graph to suit your needs and make sure that your data is accurately represented. We hope that this article has been helpful, and that you can now display absolute values on your Matplotlib Y-axis with ease!

9.9e3 9900

### Opinion

In my opinion, Matplotlib is an excellent tool for data visualization, but the default display of offset values on the Y-axis can be challenging to interpret. Displaying Matplotlib Yaxis range using absolute values offers a more accurate and easier to read representation of the data, making it simpler to compare data across different time periods or variables. The process can seem intimidating at first, but it only requires a few lines of code.

5. How can I display the y-axis range using absolute values in Matplotlib?
6. You can display the y-axis range using absolute values in Matplotlib by using the ticker.FuncFormatter() method and defining a function that converts the offset values to absolute values. Then you can set the y-axis formatter to use this function, like so:

• Define the conversion function:
• `def y_fmt(y, pos):`

` return '{:.2f}'.format(y)`

• Set the y-axis formatter to use this function:
• `ax.yaxis.set_major_formatter(ticker.FuncFormatter(y_fmt))`
