  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • Self-contained

    Everything the model needs lives in the instructions — no extra files to sync.

  • Open source

    Published by OpenSenseNova on GitHub. Read the source before you install it.

Installation

Install the Excel Statistical Viz Large File AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.
2

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/OpenSenseNova/SenseNova-Skills.git /tmp/SenseNova-Skills
mkdir -p .claude/skills
cp -r /tmp/SenseNova-Skills/skills/sn-da-excel-workflow/capability/excel-data-visualization/scatter-plot-visualization .claude/skills/excel-statistical-viz-large-file
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Excel Statistical Viz Large File in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Excel Statistical Viz Large File on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Excel Statistical Viz Large File is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

This sub-skill covers one capability of the Excel workflow. For reading/counting/Parquet optimization, see the parent workflow SKILL.md.

Step1 数据清洗与标准化。提取目标分析列,处理合并单元格(ffill),并利用正则表达式或类型转换清理数值字段,确保分析数据集的准确性。

python
import re

# 假设 target_col_x 和 target_col_y 是分析目标
# 处理合并单元格导致的缺失值
df['group_col'] = df['group_col'].fillna(method='ffill')

def clean_numeric_string(value):
    if pd.isna(value): return None
    # 保留数字、小数点和负号,移除空格及非法字符
    cleaned = re.sub(r'[^\d\.\-]', '', str(value))
    try:
        return float(cleaned)
    except ValueError:
        return None

df['x_val'] = df['target_col_x'].apply(clean_numeric_string)
df['y_val'] = df['target_col_y'].apply(clean_numeric_string)

# 过滤无效数据
df_clean = df.dropna(subset=['x_val', 'y_val']).copy()

Step2 执行多维度统计分析。计算分类占比、均值、标准差,并构建交叉分析表(crosstab/pivot),为可视化提供数据支撑。

python
# 分类统计与占比
stats_summary = df_clean.groupby('group_col')['y_val'].agg(['count', 'mean', 'std', 'min', 'max'])
stats_summary['percentage'] = (stats_summary['count'] / stats_summary['count'].sum()) * 100

# 添加总计行
total_row = pd.DataFrame(df_clean[['y_val']].agg(['count', 'mean']).T)
total_row.index = ['Total']

# 交叉分析示例
pivot_table = pd.pivot_table(df_clean, values='y_val', index='group_col', columns='category_col', aggfunc='count', fill_value=0)

Step3 生成高分辨率可视化图表。包含散点图、线性趋势线(R²、p值)、箱线图或柱状图组合,并配置中文字体与美化参数。

python
import matplotlib.pyplot as plt
import matplotlib
from scipy import stats
import numpy as np

# 字体配置:优先使用 SimHei 或 DejaVu Sans 确保中文显示
matplotlib.rcParams['font.sans-serif'] = ['SimHei', 'WenQuanYi Zen Hei', 'DejaVu Sans']
matplotlib.rcParams['axes.unicode_minus'] = False

x = df_clean['x_val'].values
y = df_clean['y_val'].values

# 线性回归计算
slope, intercept, r_value, p_value, std_err = stats.linregress(x, y)
line = slope * x + intercept

plt.figure(figsize=(12, 8), dpi=300)

# 散点图:添加随机抖动 (jitter) 避免点重叠
jitter_x = x + np.random.normal(0, 0.01, size=len(x))
plt.scatter(jitter_x, y, alpha=0.6, edgecolors='w', label='Data Points')

# 趋势线
plt.plot(x, line, color='red', linestyle='--', linewidth=2, 
         label=f'Trend: y={slope:.4f}x+{intercept:.4f}\n$R^2$={r_value**2:.4f}, p={p_value:.4e}')

# 数据点标注 (实战技巧:仅标注极值或特定点)
for i, (xi, yi) in enumerate(zip(x, y)):
    if i % (len(x)//5 or 1) == 0: # 抽样标注避免拥挤
        plt.annotate(f'({xi:.2f}, {yi:.2f})', (xi, yi), textcoords="offset points", xytext=(5,5), fontsize=8)

plt.xlabel('Dimension X')
plt.ylabel('Dimension Y')
plt.title('Statistical Distribution & Trend Analysis')
plt.grid(True, linestyle=':', alpha=0.6)
plt.legend()

output_img = 'analysis_plot.png'
plt.savefig(output_img, bbox_inches='tight')
plt.show()

Step4 导出分析结果并生成下载链接。将清洗后的数据及统计摘要保存为 CSV 或 Excel 文件。

python
output_csv = 'cleaned_analysis_data.csv'
# 使用 utf-8-sig 确保 Excel 打开中文不乱码
df_clean.to_csv(output_csv, index=False, encoding='utf-8-sig')

print(f"Visualization saved to: {output_img}")
print(f"Data exported to: {output_csv}")
# 打印回归关键指标供快速参考
print(f"R-squared: {r_value**2:.6f}, P-value: {p_value:.6f}")

Frequently asked questions

What does the Excel Statistical Viz Large File AI skill do?

对 Excel 数据进行多维度统计分析与可视化。

Why use Excel Statistical Viz Large File on TypingMind?

Because you install it once and use it with any model. Excel Statistical Viz Large File is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Excel Statistical Viz Large File in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/OpenSenseNova/SenseNova-Skills/tree/main/skills/sn-da-excel-workflow/capability/excel-data-visualization/scatter-plot-visualization. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Excel Statistical Viz Large File?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Excel Statistical Viz Large File?

As many as you like. As long as a model supports skills, you can use Excel Statistical Viz Large File with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Excel Statistical Viz Large File AI skill free?

Yes. It is published on GitHub by OpenSenseNova under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
