How to Create Interactive Plots Using the MATLAB Plots Toolstrip
The MATLAB Plots Toolstrip provides a simple and interactive way to create graphs using data stored in the Workspace. Instead of writing commands manually, users can generate different types of plots by selecting options from a visual interface. This makes the plotting process faster and easier, especially for beginners, while still being useful for advanced users who want quick results.
To start using the Plots Toolstrip, the required data must first be defined as variables. These variables, usually vectors or arrays, should be visible in the Workspace Window. Once the data is available, the user selects one variable and then, by holding the CTRL key, selects additional variables needed for the graph. The order of selection matters because the first variable becomes the independent variable (x-axis), and the second becomes the dependent variable (y-axis).
After selecting the variables, the Plots Toolstrip displays multiple icons representing different types of graphs such as line plots, scatter plots, bar charts, and pie charts. Clicking on any of these icons immediately opens a Figure Window with the selected graph displayed. This allows users to quickly visualize their data without needing to remember specific MATLAB commands.
Example 1: Line Plot
Suppose we have data showing yearly production values:
year = [2014 2015 2016 2017 2018]; production = [10 18 24 32 40];
After selecting year and production in the Workspace, clicking the line plot icon will create a graph showing how production changes over time. This type of plot is useful for identifying trends and patterns.
Example 2: Bar Chart
Using the same data, a bar chart can also be created:
year = [2014 2015 2016 2017 2018]; production = [10 18 24 32 40];
Selecting the bar chart option will display each year as a separate bar, making it easier to compare values across different years. For comparison purposes, bar plots are used commonly.
Example 3: Scatter Plot
For analyzing relationships between variables, a scatter plot can be used. For example:
x = [2 4 6 8 10]; y = [5 9 12 15 20];
Selecting these variables and choosing the scatter plot option will show individual data points. This helps in understanding how one variable changes with respect to another.
One of the most useful features of the Plots Toolstrip is that MATLAB automatically generates the command used to create the plot. This command is displayed in the Command Window. For example:
plot(year, production)
Users can copy this command and paste it into a script file. This makes it easy to reproduce the same plot in the future and helps users learn MATLAB commands gradually.
The Toolstrip also provides options such as Reuse Figure and New Figure. The Reuse Figure option updates the same graph window with a new plot style, while the New Figure option opens a separate window. This allows users to compare multiple plots side by side.
If only one variable is selected, MATLAB automatically plots its values against their index positions. For example:
data = [3 6 9 12 15];
This will create a graph where the x-axis represents the position of each element, and the y-axis represents the values. This is useful when only one dataset is available.
In conclusion, the MATLAB Plots Toolstrip makes graph creation simple, interactive, and efficient. It allows users to experiment with different types of visualizations, understand their data more clearly, and easily transition from graphical interaction to coding.
