An R Introduction to Statistics
Creating a 3D histogram with R Ask Question. How can I create a 3D histogram with R? Jin 5, 2 17 This question would fit better on CrossValidated. I have flagged it for moderator attention. I have to admit that I don't understand the closing. IMHO this question may easily be answered software-related which I understand to be the topic here: That being said, it may rather be worth closing as duplicate of stackoverflow.
I'd call two variables X and Y and their counts in Z rather a 2d histogram. A pop-up window will appear. Click the All Charts tab. It's at the top of the pop-up window. This tab is on the left side of the window. Select the Histogram model. Click the left-most bar chart icon to select the Histogram model rather than the Pareto model , then click OK.
Doing so will create a simple histogram with your selected data. Open the horizontal axis menu. Right-click the horizontal axis e. Check the "Bin width" box. It's in the middle of the menu. Enter your bin number interval. Excel will automatically format the histogram to display the appropriate number of columns based on your bin number.
For example, if you decided to use bins that increase by 10, you would type in 10 here. This is only necessary if you want to add titles to your graph's axes or the graph as a whole: Chart Title - Click the Chart Title text box at the top of the histogram, then type in the title that you want to use.
Select your data and the bins. This will highlight all of your data and the corresponding bin numbers. It's a tab in the green Excel ribbon at the top of the window. Click the bar chart icon. You'll find this in the "Charts" section of the Insert toolbar. Doing so will prompt a drop-down menu. Click the "Histogram" icon. It's the set of blue columns below the "Histogram" heading.
This will create a histogram with your data and bin numbers. Be sure not to click the "Pareto" icon, which resembles blue columns with an orange line. Before saving, make sure that your histogram looks accurate; if not, consider adjusting the bin numbers and redoing the histogram.
As such, the shape of a histogram is its most obvious and informative characteristic: In other words, you can see where the middle is in your data distribution, how close the data lie around this middle and where possible outliers are to be found.
Exactly because of all this, histograms are a great way to get to know your data! But what does that specific shape of a histogram exactly look like? In short, the histogram consists of an x-axis, an y-axis and various bars of different heights. The y-axis shows how frequently the values on the x-axis occur in the data, while the bars group ranges of values or continuous categories on the x-axis.
Since histograms require some data to be plotted in the first place, you do well importing a dataset or using one that is built into R.
This tutorial makes use of two datasets: You can simply make a histogram by using the hist function, which computes a histogram of the given data values. You put the name of your dataset in between the parentheses of this function, like this:. The default visualizations usually do not contribute much to the understanding of your histograms.
You therefore need to take one more step to reach a better and easier understanding of your histograms. Luckily, this is not too hard: R allows for several easy and fast ways to optimize the visualization of diagrams, while still using the hist function. In order to adapt your histogram, you simply need to add more arguments to the hist function, just like this:. Overwhelmed by this large string of code?
Change the title of the histogram by adding main as an argument to hist function:. To adjust the label of the x-axis, add xlab. Similarly, you can also use ylab to label the y-axis:. If you want to change the colors of the default histogram, you simply add the arguments border or col. You can adjust, as the names itself kind of give away, the borders or the colors of your histogram.
