Paste CSV or JSON and get a bar, line, pie, doughnut, radar or scatter chart you can download as PNG.
粘贴 CSV 或 JSON 数据，生成柱状图、折线图、饼图、雷达图与散点图，可下载 PNG。
A chart generator for the cases where a spreadsheet would be overkill. Paste CSV or a JSON array, pick bar, line, pie, doughnut, radar or scatter, and Chart.js draws it instantly with sensible defaults and a readable legend. The chart can be exported as a PNG at the canvas resolution, which makes it a quick way to produce a figure for a report, a ticket or a chat message.
一个在"用不着表格软件"的场景里用的图表生成器。粘贴 CSV 或 JSON 数组，选柱状图、折线图、饼图、环形图、雷达图或散点图，Chart.js 立即用合理的默认样式画出来，图例清晰可读。图表可导出为 PNG，是给报告、工单或聊天消息快速配一张图的最快路径。
A header row followed by rows, where the first column is the label and the second is the value — for example "label,value" and then "Alpha,30". Extra columns are ignored.
第一行表头，随后每行一条记录：第一列是标签，第二列是数值，例如 "label,value" 下面接 "Alpha,30"。多余的列会被忽略。
Yes, with JSON input: an array of objects whose first key is the label and whose other numeric keys become one series each.
可以，用 JSON 输入：对象数组中第一个键作为标签，其余数值键各自成为一个系列。
They are read as NaN and the point is skipped, so a stray text cell does not break the whole chart.
会被读成 NaN 并跳过该点，所以一个误输入的文本单元格不会毁掉整张图。
It exports at the canvas resolution, which is already larger than the on-screen chart. For print work, generate the chart at a larger canvas size in your own page.
按画布分辨率导出，本身就大于屏幕显示尺寸。若要用于印刷，请在自己的页面里用更大的画布尺寸生成。
