Câu hỏi thường gặp
Where can I get more chart types?
See the <a class="underline" href="/bar-chart-maker">Bar Chart Maker</a>, <a class="underline" href="/pie-chart-maker">Pie</a>, <a class="underline" href="/doughnut-chart-maker">Doughnut</a> and <a class="underline" href="/scatter-plot-maker">Scatter</a> tools — they all share the same CSV input shape.
What if my data is in JSON?
Convert it first with the <a class="underline" href="/csv-to-json">CSV ↔ JSON</a> converter, then paste the CSV here.
Why are some cells ignored?
Non-numeric cells in data columns become null. The first column is treated as a label string, all other columns must parse as numbers to plot.
Line Chart Maker là gì?
A Line Chart Maker is a tool that turns pasted CSV data into a line chart directly in the browser. It plots one or more data series as connected points along an axis, offers a slider to smooth the curve between points, and exports the rendered result as a PNG image, with all processing happening client-side and nothing uploaded to a server.
