This node has been copied to display text without requiring the user to install the above custom nodes package. However, if you already have ComfyUI-Custom-Scripts, you can also use the Show Text node from the package.
## Displaying DataFrame contents
Use **Pandas Show DataFrame** node. When the number of rows is large, Pandas automatically hides middle rows during string conversion, so the display size should be always manageable.

## Summary statistics
You can compute summary statistics for each row in a DataFrame using below nodes:
* **Pandas Count** to get the number of rows.
* **Pandas Min** to get the minimum row value.
* **Pandas Max** to get the maximum value of row values.
* **Pandas Mean** to get the mean of row values.
* **Pandas Median** to get the median of row values.
* **Pandas Mode** to get the mode of row values.
* **Pandas Sum** to get the sum of row values.
* **Pandas Std** to get the standard deviation of row values.
* **Pandas Var** to get the variance of row values.
All nodes return a Series except for Pandas Mode, which returns a DataFrame. This is necessary because multiple values may occur with the highest frequency. For example:
```
apple
apple
apple
banana
donut
coconut
coconut
coconut
```
In this case, both apple and coconut are the mode.
## Convert DataFrame to a string
Use **Pandas To String**. This node is to convert the DataFrame to a displayable string, and this truncates the data when the data is large. This can be used to display the data content in a text display node (e.g. Show Text node). However, you can use Show DataFrame nodes to display the DataFrame content, so you do not normally need to use this.
