How do I get 2 y axis in ggplot2?

How do I get 2 y axis in ggplot2?

ggplot2 dual axes support scale_x_continuous() and scale_y_continuous() can now display a secondary axis that is a one-to-one transformation of the primary axis (e.g. degrees Celcius to degrees Fahrenheit). The secondary axis will be positioned opposite to the primary axis and can be controlled with the sec.

How do I remove a legend in R?

Remove a ggplot legend

1. Remove the legend title: p + theme(legend. title = element_blank()) .
2. Hide the entire legend to create a ggplot with no legend. Example of R code: p + theme(legend. position = “none”) .
3. Hide legend for a specific geometry, say geom_text() . Just specify the argument show.

How do I change the axis scale in R?

To change the axis scales on a plot in base R, we can use the xlim() and ylim() functions.

What is XLIM and YLIM in R?

You can use the xlim() and ylim() functions to set the x-axis limits and y-axis limits of plots in R.

How do you add a legend in R?

R legend position, lines and fill When adding a legend to a plot, there are two main ways to modify the legend position with the R legend function. On the one hand, you can set the argument x to “top” , “topleft” , “topright” , “bottom” , “bottomleft” , “bottomright” , “left” , “right” or “center” .

How do I change axis titles in R?

Key ggplot2 R functions

1. p + xlab(“New X axis label”): Change the X axis label.
2. p + ylab(“New Y axis label”): Change the Y axis label.
3. p + labs(x = “New X axis label”, y = “New Y axis label”): Change both x and y axis labels.

How do I change the legend position in R?

How do you change the Y axis labels in R?

Do you need a second y axis for a graph?

One could easily build 2 line charts to study the evolution of those 2 series using the code below. But even if strongly unadvised, one sometimes wants to display both series on the same chart, thus needing a second Y axis. sec.axis () does not allow to build an entirely new Y axis.

Why is bar data plotted on the original axis?

Your bar_data is still being plotted on the original axis, which only goes up to 0.5 because of your limits. This prevents the bars from appearing. In order to make the data show up in the same range, you have to normalize the bar data so that it falls in the same range as the point data.

Is the second axis the same as the primary axis?

A couple of notes though: Remember that the second axis is created by a 1-1 transformation of the primary axis, so make sure they cover the same limits under the transformation. If you have bars that should go to zero, the primary axis should include the untransformed analogue of zero.
