# Panel Types

Wuji Studio provides the following visualization panels:

| Panel type | Description |
| - | - |
| 3D View | Renders hand skeleton, fingertip poses, and more in 3D space (see [3D Hand Visualization](https://docs.wuji.tech/docs/en/wuji-studio/latest/visualization/hand-3d.md)) |
| Plot | Displays numerical data as time-series line charts |
| Tactile Matrix | Visualizes tactile sensor data as a color-coded matrix heatmap |
| Raw Messages | Displays Topic raw message content in JSON format with two-frame diff comparison |
| Tab | Groups multiple panels into tabs to save screen space |

## Plot

Displays numerical data as time-series line charts.

## Tactile Matrix

Visualizes tactile sensor data as a color-coded matrix heatmap.

![Tactile Matrix](https://mintcdn.com/wuji-0bbde051/5Gi8SRDtLtPD19Vi/shared/assets/source/images/en/wuji-studio/matrix.png?fit=max\&auto=format\&n=5Gi8SRDtLtPD19Vi\&q=85\&s=e921091812488d45a8f4d8c918112a18)

Switch colormaps from the **Color Map** dropdown in the Sidebar's **Panel** section. The default is Viridis (perceptually uniform), and Safety (Okabe-Ito) is the accessibility-friendly option.

| Setting | Description |
| - | - |
| Min Value / Max Value | 0.0 \~ 1.0 (normalized) Invalid data points (value -1) are automatically skipped during rendering. |
| Zoom / Flip Horizontal / Flip Vertical | Supports horizontal/vertical flip and zoom |
| Show Value | Display numerical value in each cell |

The tactile sensor matrix is 24 × 31, divided into 6 zones:

| Zone ID | Region | Matrix Size |
| - | - | - |
| 6 | Palm | 14 × 22 |
| 1 | Thumb | 10 × 5 |
| 2 | Index | 9 × 5 |
| 3 | Middle | 10 × 6 |
| 4 | Ring | 9 × 6 |
| 5 | Pinky | 11 × 5 |

Starting with firmware v0.11.0, the tactile matrix changes from 24×32 (768 values) to 24×31 (744 values), removing invalid column 26 from the 24×32 layout. The remaining columns keep their relative order: columns 0–25 keep their indices, and columns 27–31 shift left to become columns 26–30.
