Matlab: interactive exploration of plotted data - examples with source code
Matlab is a powerful mathematical calculation software and an efficient engineering software, which is widely used in various fields. This article will introduce how to use Matlab to interactively explore the plot data, allowing you to easily visualize the data and gain an in-depth understanding of the characteristics and laws of the data.
Before using Matlab for data visualization, you need to import the data first. Assuming we want to perform visual analysis on some car sales data, we first need to organize the data in the following format and save it to an Excel file named "car_sales.xlsx":
| car_model | sales_num | date |
|---|---|---|
| A | 500 | 2021/1/1 |
| B | 800 | 2021/2/1 |
| C | 1200 | 2021/3/1 |
| D | 600 | 2021/4/1 |
| E | 1500 | 2021/5/1 |
Then, open the editor in Matlab and enter the following code:
% 导入数据
car_sales = readtable('car_sales.xlsx'
