Error bars in Plotly 2.0

A graphical representation of the variability of data used on graphs to indicate the error, or uncertainty in a reported measurement.

Step 1

Try an Example

Error bars give a general idea of how precise a measurement is, or how far from the reported value the true (error free) value might be.

After selecting 'Error Bars' under 'Chart Type', you can check out an example before adding your own data. Clicking the 'try an example' button will show what a sample chart looks like after adding data and playing with the style. You'll also see what values and style attributes were selected for this specific chart, as well as the end result. This is an example of error bars in a scatter chart.

You can also use the data featured in this tutorial by clicking on 'Open This Data in Plotly' on the left-hand side. It'll open in your workspace.

Step 2

Add Your Data to Plotly

Head to Plotly’s new online workspace and add your data. You have the option of typing directly in the grid, uploading your file, or entering a URL of an online dataset. Plotly accepts .xls, .xlsx, or .csv files. For more information on how to enter your data, see this tutorial.
