to represent the overall distribution of the data. Let's take, for example, the impact energy absorbed by a metal at various temperatures. In this case, the temperature of the metal is https://www.mathworks.com/help/matlab/ref/errorbar.html the independent variable being manipulated by the researcher and the amount of energy absorbed is the dependent variable being recorded. Because there is not perfect precision in recording this absorbed energy, five different metal bars are tested at each temperature level. The resulting data (and graph) might look like this: For clarity, the data for each level of the independent variable (temperature) has https://www.ncsu.edu/labwrite/res/gt/gt-stat-home.html been plotted on the scatter plot in a different color and symbol. Notice the range of energy values recorded at each of the temperatures. At -195 degrees, the energy values (shown in blue diamonds) all hover around 0 joules. On the other hand, at both 0 and 20 degrees, the values range quite a bit. In fact, there are a number of measurements at 0 degrees (shown in purple squares) that are very close to measurements taken at 20 degrees (shown in light blue triangles). These ranges in values represent the uncertainty in our measurement. Can we say there is any difference in energy level at 0 and 20 degrees? One way to do this is to use the descriptive statistic, mean. The mean, or average, of a group of values describes a middle point, or central tendency, about which data points vary. Without going into detail, the mean is a way of summarizing a group of data and stating a best guess at what the true value of the dependent variable value is for that independent variable level. In this example, it would be a

Back to Tutorials 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. Step 3 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. Step 4 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.
