How to use the Chart Maker from CSV
- 1. Add your dataPaste CSV or upload a file. The first row holds the column names.
- 2. Choose the chartPick the chart type, the label column and one or more value columns.
- 3. Make and savePress Make chart, adjust the title, then download it as PNG.
Choosing the right chart
- Bar: compare amounts across categories such as products or cities. Use horizontal bars when the labels are long.
- Line: show change over time, such as monthly sales. Put the dates or months in the label column.
- Pie or doughnut: show shares of one total. Keep it to about six slices; beyond that a bar chart is easier to read.
- Scatter: see whether two number columns move together, such as study hours and marks.
Several value columns become several series in bar and line charts, each in its own colour. Pie charts show only one column.
Worked example
The sample data has six months of Sales and Expenses. Make a bar chart and the summary under it shows Sales with a total of 2,95,000 and an average of 49,166.67, and Expenses with a total of 1,94,000 and an average of 32,333.33. Switch to Line to see that sales rose faster than expenses from April to June.
Tips for charts people actually read:
- Write a title that says the point, such as "Sales grew 45% from January to June", not just "Sales".
- Remove columns that do not help the message.
- Clean numbers before charting: values like "42,000" or "₹42000" are not read as numbers.
The chart is drawn with Chart.js, an open-source library loaded from cdnjs, and your data never leaves the browser.
Frequently asked questions
Why does my column not appear under Value columns?
Only columns with numbers are listed. Remove currency signs and thousands separators from the values first.
Can I change colours?
Colours are set automatically from a fixed palette so series stay easy to tell apart. Edit the PNG in an image editor if you need brand colours.
How big can the data be?
Up to 2,000 rows. For more, summarise the data first, for example with the pivot table maker.
Is the chart maker free?
Yes, free to use. Your first chart asks for a name and WhatsApp number once, then charts and all other Uncodemy tools work without it.
