# How to choose plot type

* **Trends** - A trend is defined as a pattern of change.
  * `sns.lineplot` - **Line charts** are best to show trends over a period of time, and multiple lines can be used to show trends in more than one group.
* **Relationship** - There are many different chart types that you can use to understand relationships between variables in your data.
  * `sns.barplot` - **Bar charts** are useful for comparing quantities corresponding to different groups.
  * `sns.heatmap` - **Heatmaps** can be used to find color-coded patterns in tables of numbers.
  * `sns.scatterplot` - **Scatter plots** show the relationship between two continuous variables; if color-coded, we can also show the relationship with a third [categorical variable](https://en.wikipedia.org/wiki/Categorical_variable).
  * `sns.regplot` - Including a **regression line** in the scatter plot makes it easier to see any linear relationship between two variables.
  * `sns.lmplot` - This command is useful for drawing multiple regression lines, if the scatter plot contains multiple, color-coded groups.
  * `sns.swarmplot` - **Categorical scatter plots** show the relationship between a continuous variable and a categorical variable.
* **Distribution** - We visualize distributions to show the possible values that we can expect to see in a variable, along with how likely they are.
  * `sns.histplot` - **Histograms** show the distribution of a single numerical variable.
  * `sns.kdeplot` - **KDE plots** (or **2D KDE plots**) show an estimated, smooth distribution of a single numerical variable (or two numerical variables).
  * `sns.jointplot` - This command is useful for simultaneously displaying a 2D KDE plot with the corresponding KDE plots for each individual variable.
