In this tutorial, you will learn how to create a smooth line chart using DataPicta. A smooth line chart is useful for visualizing trends in data over time or categories, with a visually appealing curved line instead of sharp angles.

Open the DataPicta app

• Open the DataPicta app by going to app.datapicta.com (this will open separate browser tab).
• If you never used DataPicta before, you will only see a button for uploading data.
• If you have used DataPicta before, click on 'New blank chart' in the menu in the top right corner.

Upload your data

• Click on the plus icon (+) next to 'Data'.
• You have two options for uploading your data:
  • Upload a file from your computer in CSV or TSV format.
  • Paste or type your data directly into the text area.
• In this example, we will copy and paste the following data:

Day,Value
Mon,150
Tue,230
Wed,224
Thu,218
Fri,135
Sat,147
Sun,260

• After pasting the data, click on 'Add data'.
• Your data should now be visible in the data table.

Create the line chart

• Click on the plus icon (+) next to 'Picta'.
• Select 'Line picta' from the list of pictas.

As you can see, the line chart is created with straight lines connecting the data points. Lets make the line smooth.

Smooth the line

• With the line pannel open, find the smooth option.
• Set the smooth option to about 50%.

You should now see a smooth line chart like this:
