Follow these easy steps to get started ~

Copy your data from the source (preferably a spreadsheet) and paste it in the data grid below.
Make adjustments as required. Try not to have any empty rows/columns. (If you have missing data, make sure the cells are either empty or have "null" in them.)
Hit Update Headers on the left panel under "Data Options" section and select Span Gaps if you want two points connected which have a null value between them.
Make required adjustments under the "Plotting Options" section as well. You can select the chart type, colors, set the title/subtitle and the chart's dimensions as well.
Once you're done, hit Plot and bam! You should have your chart.
Next up you can try the Analyze feature and/or download the result.
