Making a Simple Line Graph in SigmaPlot 13

TL;DR

Learn how to create a basic line graph with error bars in Sigma Plot 13.

Transcript

so here we are in Sigma plot 13 and we're going to make ourselves a very simple line graph where we have an x axis with numerical information maybe relating to time or or dose of a drug and then we're going to have Y data consisting of an average of a number of data points so for instance we might have data time zero one minute two minute three min...

Key Insights

• 🫥 Sigma Plot 13 allows for easy creation of line graphs with labeled axes and grouped data.
• 🤢 You can add error bars to represent standard deviation or standard error.
• 🍱 Graph customization options include changing the scale of the axes and hiding unnecessary legends and boxes.
• 💨 To perform statistical tests like a one-way ANOVA, ensure the data is in a suitable format with columns for comparisons.
• 🛀 While the provided data may not pass a normality test, this demonstration shows how to interpret the results of a statistical analysis in Sigma Plot.
• 🤩 Text annotations can be used to add stars or other symbols to indicate significant changes on the graph.

Questions & Answers

Q: How can you label each column in Sigma Plot 13?

Right-click on the column, choose column titles, and enter the desired label. This helps differentiate between x-axis data and different experimental groups.

Q: How do you create a line graph with error bars in Sigma Plot 13?

Select the option for a combination line scatter graph with error bars. This will display the mean values of the data points with error bars representing standard deviation or standard error.

Q: Can you change the scale of the x-axis in the graph?

Yes, you can double-click on the x-axis line, adjust the scale settings, and choose the desired minimum and maximum values for the x-axis.

Q: How can you perform statistical analysis on the data in Sigma Plot 13?

To perform statistical analysis, you may need to reformat the data into columns. For example, for a one-way ANOVA, transpose the data and compare the rows. Then, select the appropriate analysis tool from the dropdown menu.

Summary & Key Takeaways

• In Sigma Plot 13, you can create a line graph with an x-axis representing time or dose and a y-axis displaying the average of multiple data points.

• By labeling each column, you can differentiate between different time points or experimental groups.

• To create the graph, choose the option for a combination line scatter graph with error bars, and input the appropriate data sets.
