If you count the frequency of letters in a message, then have one axis with letters and another with numbers, is that a histogram or a bar graph or something different still?
When we scroll almost to the end of the ppt link in your "Here" hyperlink, the author discusses "Graphs that are not graphs", shows a chart with category versus numerical values, and calls this type a "bar diagram". So that's how you might call yours in general if you want.lewando said:I vote for histogram. Here is a definition that does not contain the phrase "numerical data".
If you are looking for "publishable quality" then there are more significant things to address with your graphs (assuming the images are your final effort). Labels for all axes, graph title, color scheme, elimination of chartjunk to start.
Here is a nice presentation that seems generally relevant.
The type of graph can be determined by looking at the data being represented and the way it is being visualized. Common types of graphs include bar graphs, line graphs, pie charts, scatter plots, and histograms.
The purpose of using a specific type of graph is to effectively communicate the data being presented. Different types of graphs are suitable for different types of data and can highlight different patterns or trends.
To choose the right type of graph for your data, consider the type of data you have, the relationship between variables, and the story you want to tell with your data. Consulting with a statistician or data visualization expert can also be helpful.
Yes, a graph can have more than one type. For example, a bar graph can also include a line graph to show trends over time, or a pie chart can include labels and percentages to display more detailed information.
Some common mistakes to avoid when creating a graph include using a misleading scale, not labeling the axes and units clearly, and using 3D effects or excessive colors that can distract from the data being presented. It is important to keep the graph simple and easy to understand.
