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.
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.
Create a Chart
After adding your own data, go to GRAPH on the left-hand side, then 'Create'. Choose 'Error Bars' under 'Chart type'.
Click on GRAPH on the left-hand side to add your values to your error bar. After selecting ‘Error Bars', you should then fill out the X, Y, and error bar dropdown to create the plot.
This will create a raw scatter graph with error bars, as seen below.
Style a Chart
You can choose your colours, text position, or typeface. Click on STYLE on the left-hand side to play around with the style of your chart.
To change the color of the points, click on ‘Traces’ under the same STYLE tab. Note that certain colors and typeface are only available with a PRO subscription. Click here to upgrade!
Additionally, this section allows you to change the diameter of the points and also the symbol.
To add a title to your plot, you can type it directly on the title by double-clicking it.
The same can be done for the axis labels, and legend.
Another option is to visit the 'Layout' section under STYLE, click on 'Text' and enter your title in the box, as shown below.
Save and Share
Your chart is now done! Click SAVE on the left-hand side.
Give your file a name, then select your PLOT and DATA as 'Public' or 'Private'. For more information on how sharing works, including the difference between private, public and secret sharing, visit this page.
