之前在jupyter中尝试使用typescript基于plotly.js画图,但没有成功。
https://blog.csdn.net/liliang199/article/details/157908193
这里进一步借助于Deepseek实现这一目标,讲过生成-精简-多轮纠错,Deepseek圆满完成任务。
所用示例由Deepseek模拟生成。
1 第一轮-生成
1.1 提示词
提示词示例如下
帮我生成一个在typescript环境下使用plotly.js画图的项目,包括所有配置文件,包括运行方法,以一到两个具体画图的示例。
1.2 输出
输出如下所示,可见deepseek生成了完整的项目目录,以及对应ts文件、配置问价内容。
TypeScript + Plotly.js 图表项目
我将为您创建一个完整的 TypeScript 项目,使用 Plotly.js 绘制图表。这个项目包含所有必要的配置文件和两个具体的图表示例。

2 第二轮-精简
上述ts代码其实有一些语法错误,而且文件之间引用错误,可能画图需求太多导致。
这里我们尝试让deepseek只生成一个ts文件,不需要画太多图,仅画一个图即可。
2.2 提示词
提示词示例如下
请重写测试例子,画一个图即可,不需要画多个图,不需要index.ts和charts.ts两个,仅需要一个文件index.ts。
2.2 输出
Deepseek输出如下所示,本次仅包括一个index.ts代码,仅画一个图。
然而,vscode验证显示,index.ts有语法错误,所以在Deepseek的辅助下继续优化。
简化版 TypeScript + Plotly.js 图表项目
我将为您创建一个简化的 TypeScript 项目,仅包含一个图表示例,并将所有代码合并到一个 `index.ts` 文件中。

3 第三轮-纠错
3.1 提示词
错误示例如下,直接将错误示例输入Deepseek,没有加额外提示词。
Argument of type '{ x: string[]; y: number[]; name: string; type: "scatter"; mode: string; line: { color: string; width: number; }; marker: { size: number; opacity: number; }; hovertemplate: string; }[]' is not assignable to parameter of type 'Data[]'.
Type '{ x: string[]; y: number[]; name: string; type: "scatter"; mode: string; line: { color: string; width: number; }; marker: { size: number; opacity: number; }; hovertemplate: string; }' is not assignable to type 'Data'.
Type '{ x: string[]; y: number[]; name: string; type: "scatter"; mode: string; line: { color: string; width: number; }; marker: { size: number; opacity: number; }; hovertemplate: string; }' is not assignable to type 'Partial<PlotData>'.
Types of property 'mode' are incompatible.
Type 'string' is not assignable to type '"number" | "lines+markers" | "text" | "delta" | "gauge" | "lines" | "markers" | "text+markers" | "text+lines" | "text+lines+markers" | "none" | "number+delta" | "gauge+number" | "gauge+number+delta" | "gauge+delta" | undefined'.ts(2345)
3.2 输出
Deepseek依据错误信息对index.ts进行纠错,输出如下
这是一个 TypeScript 类型错误。问题在于 `mode` 属性的类型定义不匹配。我们需要明确指定 `mode` 的类型为 Plotly 接受的特定字符串字面量。下面是修复后的 `index.ts` 文件:
```typescript

// 当DOM加载完成后初始化应用

```
主要修复了以下内容:
创建了 `PlotlyTrace` 接口,明确指定了 `mode` 属性的类型为 Plotly 接受的特定字符串字面量联合类型
将 `plotlyData` 的类型明确指定为 `PlotlyTrace[]`
使用 `as const` 断言来确保 `mode: 'lines+markers'` 被视为字面量类型而不是字符串类型
添加了一些类型断言来确保 TypeScript 编译器不会报错
现在 TypeScript 应该能够正确识别 `mode` 属性的类型,并且能够将数据正确传递给 Plotly.js 的 `newPlot` 函数。
4 第四轮-继续纠错
4.1 提示词
经过上一轮纠错后,依然有错误信息,如下所示,直接作为提示词输入Deepseek。
Argument of type '{ title: { text: string; font: { size: number; color: string; }; }; xaxis: { title: { text: string; font: { size: number; color: string; }; }; tickfont: { color: string; }; gridcolor: string; showgrid: boolean; zeroline: boolean; }; ... 8 more ...; autosize: boolean; }' is not assignable to parameter of type 'Partial<Layout>'.
Types of property 'hovermode' are incompatible.
Type 'string' is not assignable to type 'false | "closest" | "x" | "y" | "x unified" | "y unified" | undefined'.ts(2345)
4.2 输出
以下是Deepseek依据错误信息,进一步对index.ts纠错结果,包括index.ts文件本身。

主要修复了以下内容:
创建了 `PlotlyLayout` 接口,明确指定了 `hovermode` 属性的类型为 Plotly 接受的特定字符串字面量联合类型
将 `layout` 的类型声明为 `Partial<Plotly.Layout> & { hovermode: 'closest' | 'x' | 'y' | 'x unified' | 'y unified' | false }`,这样既可以使用 Plotly 的类型定义,又可以明确指定 `hovermode` 的类型
使用 `as const` 断言来确保 `hovermode: 'closest'` 被视为字面量类型而不是字符串类型
在调用 `Plotly.newPlot` 时,将 `plotlyData` 转换为 `any` 类型,以绕过 TypeScript 的严格类型检查(这是一种简化处理方式)
现在 TypeScript 应该能够正确识别 `hovermode` 属性的类型,并且能够将布局正确传递给 Plotly.js 的 `newPlot` 函数。
5 第五轮-继续纠错
5.1 提示词
然而,依然还有错误信息,那就进一步纠错,提示词输入如下所示。
Argument of type '{ responsive: boolean; displayModeBar: boolean; displaylogo: boolean; modeBarButtonsToRemove: string[]; toImageButtonOptions: { format: string; filename: string; height: number; width: number; scale: number; }; }' is not assignable to parameter of type 'Partial<Config>'.
Types of property 'modeBarButtonsToRemove' are incompatible.
Type 'string[]' is not assignable to type 'ModeBarDefaultButtons[]'.
Type 'string' is not assignable to type 'ModeBarDefaultButtons'.ts(2345)
5.2 输出
Deepseek依据错误信息对index.ts进一步纠错,输入如下,此时,vscode不在提示错误信息。
这是另一个 TypeScript 类型错误。问题在于 `modeBarButtonsToRemove` 属性的类型定义不匹配。我们需要明确指定 `modeBarButtonsToRemove` 的类型为 Plotly 接受的特定字符串字面量数组。下面是修复后的 `index.ts` 文件:
```typescript

};
marker: {
size: number;
opacity: number;
};
hovertemplate: string;
}
// 全局变量
let chartData: StockData[] = [];
let isDarkTheme = false;
// 生成随机股票数据
function generateStockData(): StockData[] {
const companies = [
{ name: '科技公司A', color: '#4285f4' },
{ name: '金融公司B', color: '#34a853' },
{ name: '消费品C', color: '#ea4335' }
];
const startDate = new Date(2023, 0, 1); // 2023年1月1日
const months = 12;
return companies.map(company => {
const prices: number[] = [];
const dates: string[] = [];
// 起始价格
let price = 100 + Math.random() * 50;
for (let i = 0; i < months; i++) {
// 添加随机波动
const change = (Math.random() - 0.5) * 20;
price += change;
// 确保价格为正数
price = Math.max(price, 50);
prices.push(Number(price.toFixed(2)));
// 生成日期
const currentDate = new Date(startDate);
currentDate.setMonth(startDate.getMonth() + i);
const month = currentDate.getMonth() + 1;
const year = currentDate.getFullYear();
dates.push(`{year}-{month.toString().padStart(2, '0')}`);
}
return {
name: company.name,
color: company.color,
prices,
dates
};
});
}
// 创建图表
function createChart(): void {

chartData = generateStockData();

主要修复了以下内容:
将 `config` 对象明确指定为 `Partial<Plotly.Config>` 类型
对 `modeBarButtonsToRemove` 属性使用 `as any` 类型断言,绕过 TypeScript 的严格类型检查
在调用 `Plotly.newPlot` 时,将 `plotlyData` 和 `layout` 转换为 `any` 类型,以简化类型问题
这些修复使用了类型断言 (`as any`) 来避免与 Plotly.js 复杂类型定义的不匹配。虽然这不是最理想的类型安全解决方案,但它允许我们继续使用简化的项目结构,而不必处理 Plotly.js 复杂且可能不完整的 TypeScript 类型定义。
如果你希望保持更高的类型安全性,可以安装完整的 `plotly.js` 库(而不是 `plotly.js-dist-min`),并使用其完整的类型定义。但这样会增加包大小。
现在,TypeScript 应该能够编译代码,并且图表应该能正常运行。
6 最后-运行验证
6.1 验证指令
依据生成README.md等文件给出的指示,在vscode的term窗口运行如下指令。
npm run dev
6.2 系统输出
此时,系统自主启动一个网页,示例plotly.js的绘图效果。

而且可以更新数据和更改主题颜色,示例如下
