Function for making a correlation matrix plot, using ggplot2. The function is directly inspired by Tian Zheng and Yu-Sung Su's corrplot function in the 'arm' package.

If any of the columns contain non-numeric data, they will be dropped with a warning. The first value gives the method for computing covariances in the presence of missing values, and must be an abbreviation of one of "everything""all. The second value gives the type of correlation coefficient to compute, and must be one of "pearson""kendall" or "spearman".

See cor for details. Defaults to c "pairwise", "pearson". Defaults to the correlation matrix of data when data is supplied. See 'Note'. Defaults to NULL no breaks, continuous scaling. Defaults to 2. Defaults to "" no legend name. Defaults to " 3B9AB2" blue. Defaults to " F21A00" red. Defaults to 0. Defaults to NULL. Accepts either "tile""circle""text" or "blank".

Defaults to 6. Also accepts any numeric value between 0 and 1in which case the level of transparency is set to that fixed value. Defaults to 0 no expansion. Defaults to "bottom". Defaults to 9. Recommended values for the nbreaks argument are 3 to 11as values above 11 are visually difficult to separate and are not supported by diverging ColorBrewer palettes. Created by DataCamp.

Put your R skills to the test Start Now.The ggcorr function is a visualization function to plot correlation matrixes as ggplot2 objects. It was inspired by a Stack Overflow question.

Correlation matrixes show the correlation coefficients between a relatively large number of continuous variables. However, while R offers a simple way to create such matrixes through the cor function, it does not offer a plotting method for the matrixes created by that function.

In practice, its results are graphically close to those of the corrplot function, which is part of the excellent arm package. The main package dependency of ggcorr is the ggplot2 package for plot construction. The ggplot2 package can be installed from CRAN through install. Doing so will also install the reshape2 package, which is used internally by ggcorr for data manipulation. This example shows the default output of ggcorr.

It also produced a warning to indicate that one column of the dataset did not contain numeric data and was therefore dropped from the correlation matrix.

ggcorr: correlation matrixes with ggplot2

The warning can be avoided by dropping the column from the dataset passed to ggcorr :. Note: when used with a continuous color scale, ggcorr also currently produces a warning related to color interpolation. This is an innocuous warning that should disappear in future updates of the ggplot2 and scales packages.

This warning is hidden in the rest of this vignette. The first argument of ggcorr is called data. It accepts either a data frame, as shown above, or a matrix of observations, which will be converted to a data frame before plotting:.

The method is controlled by the method argument, which takes two character strings:. If no second argument is provided, ggcorr will default to "pearson". The rest of this vignettes focuses on how to tweak the aspect of the correlation matrix plotted by ggcorr.

To switch to categorical colors, all the user has to do is to add the nbreaks argument, which specifies how many breaks should be contained in the color scale:. When the nbreaks argument is used, the number of digits shown in the color scale is controlled through the digits argument. The digits argument defaults to two digits, but as shown in the example above, it will default to a single digit if the breaks do not require more precision.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

The graph is fine and I can adjust the cl labels all I want. I've tried adjusting the labels on x and y axis with no impact. I looked at changing mar - yet I haven't found a way to.

Customize x-axis and y-axis properties

I was unsuccessful with trying to use cex. The question - how can I make the text appearing for corrplot not the cl, and not in the grid larger? The corrplot maintainer wrote back with an alternate corrplot. Using the this corrplot and the example code below, the text size is acceptable.

However, attempts to increase it also produce the same effects. Using an earlier version of the correlation circles available hereit is possible to adjust the text to one's heart desire. Though the graph lacks some of the functionality of the later, more refined corrplot package.

I may try to tweak the two to come up with a happy medium as time permits. Using the older correlation circles script, the following code produces sufficiently large X and Y axis labels:.

The dev. The tl. I include the two figures below:. As you can see, I can't reproduce the problem you are seeing; tl. Note this is without using tl. Compare it with the one on your system and try the example above so we are running exactly the same code for comparison. Ok, I see the problem now. With tl.

Learning R in RStudio: corrplot

This seems either a bug on infelicity in corrplot as if you don't set tl. The only solution I can see is to not set tl. You can improve things, by altering the relative dimensions of the plot device - if on screen, increase the width or height or both of the plot device window until all the labels are visible.

If this is another device pdf or png saythen you'll need to alter the dimensions of the device when you create it.

You aren't clear what the problem with the x and y axis labels, but corrplot alters the plot margins to accommodate the labels. You have already stated the relative size of these x and y axis labels by setting argument tl.

If you want the labels bigger, increase this value:. Given these are the only x and y labels on the plot, does this help? If not, which labels need altering? Given the examples you added, you might have to increase the dimensions of the plot and set the outer margins to accommodate the length of your labels.

You could try changing the point size of text with par. I think the default size is How are we doing? Please help us improve Stack Overflow. Take our short survey.The steps and illustrations in this article are from Power BI Desktop. In this tutorial, you'll learn many different ways to customize the X-axis and Y-axis of your visuals. Not all visuals have axes.

Pie charts, for example, don't have axes. And customization options vary from visual to visual. There are too many options to cover in a single article, so we'll take a look at some of the most-used customizations and get comfortable using the visual Format pane in the Power BI report canvas. Watch Amanda customize her X- and Y-axes. She'll also demonstrate the different ways to control concatenation when using drill down and drill up.

Retail Analysis Sample. From the Visualizations pane, select the stacked column chart icon. This adds an empty template to your report canvas.

ggcorrplot axis labels

Now you can customize your X-axis. Power BI gives you almost limitless options for formatting your visualization. There are many features that are customizable for the X-axis. You can add and modify the data labels and X-axis title. For categories, you can modify the width, size, and padding of bars, columns, lines, and areas. And for values, you can modify the display units, decimal places, and grid lines.

The following example shows customization for a column chart. Let's add a few customizations to get you familiar with the options and then you can explore the rest on your own. The X-axis labels display below the columns in the chart. Right now, they're light grey, small, and difficult to read.

Let's change that. In the Visualizations pane, select Format the paint roller icon to reveal the customization options. Some reasons you may want to set the X axis to Offis if the visualization is self-explanatory without labels or if you have a crowded report page and need to make space to display more data.

Maybe you don't like the way the X-axis text is displayed on a diagonal. You have several options. Here, we've selected the second option and grabbed one of the resize bars to make the visualization wider.

It now accommodates the point text without needing to display the text on an angle or with a scrollbar. The first thing you'll notice is that your visualization now has a default X-axis title. In this case, it's FiscalMonth. Save the changes you've made and move to the next section.Documentation Help Center. This example shows how to add a title and axis labels to a chart by using the titlexlabeland ylabel functions. It also shows how to customize the appearance of the axes text by changing the font size.

Create y1 and y2 as sine and cosine values of x. Plot both sets of data. Add a title to the chart by using the title function. Add axis labels to the chart by using the xlabel and ylabel functions. Add a legend to the graph that identifies each data set using the legend function. Specify the legend descriptions in the order that you plot the lines. Optionally, specify the legend location using one of the eight cardinal or intercardinal directions, in this case, 'southwest'.

ggcorrplot axis labels

Axes objects have properties that you can use to customize the appearance of the axes. For example, the FontSize property controls the font size of the title, labels, and legend.

Access the current Axes object using the gca function. Then use dot notation to set the FontSize property. Include a variable value in the title text by using the num2str function to convert the value to text. You can use a similar approach to add variable values to axis labels or legend entries.
