The page consists of eight examples for the creation of barplots. More precisely, the article will consist of this information:. First, we need to create a vector containing the values of our bars:. Figure 1 shows the output of the previous R code: A barchart with five bars.
However, you can also see that our basic barchart is very plain and simple. So keep on reading! Note that you could change the color of your bars to whatever color you want. Either you can use HEX-Codes or you could use predefined color names. You can find an overview of colors here. We can align the bars of our bargrah horizontally by specifying the horiz option to be equal to TRUE:.
Figure 3: Barchart with Horizontal Alignment. Figure 3 shows exactly the same bars and values as the previous examples, but this time with horizontal bars instead of vertical bars. It makes a lot of sense to add labels to our barchart in order to show the reader the meaning of each bar.
First, we need to specify a vector consisting of the labels of our bars:. Note that the vector containing our labels needs to have the same length and ordering as the vector containing our values. When we have data with several subgroups e. For this task, we need to create some new example data:.
Now, we can draw a stacked barchart by specifying our previously created matrix as input data for the barplot function:. Furthermore, we should add a legend to our stacked bargraph to illustrate the meaning of each color:. Figure 5: Stacked Barchart with Legend in R. Figure 5 shows our stacked bargraph. It contains five bars, whereby each of the bars consists of two subgroups. The legend on the topright illustrates the meaning of the two colors of each bar.
Depending on our specific data situation it may be better to print a grouped barplot instead of a stacked barplot as shown in Example 5. Figure 6: Grouped Barchart with Legend in R. Compare Figure 5 and Figure 6. Both graphics contain the same values, once in a stacked barchart and once in a grouped barchart.
So far, we have created all barplots with the base installation of the R programming language. However, there are multiple packages available that also provide functions for the drawing of barcharts. First, we need to install and load the package:. Then, we also need to store our group and value variables in a data frame — That is required by the functions of the ggplot2 package:. Figure 7: Barchart Created with ggplot2 Package.
Figure 7 shows bars with the same values as in Examples However, this time the bargraph is shown in the typical ggplot2 design. Another powerful R add-on package for the printing of barcharts is the plotly package.
We can use this function to make a barchart as follows:. Figure 8: Barchart Created with plotly Package. I have recently released a video on my YouTube channel, which illustrates the R programming syntax of this tutorial. You can find the video below:.
In this R tutorial you learned how to create a barplot with multiple bars.By Joseph Schmuller. The image below shows an example.
Plotly r show legend
The bar plot shows the frequency of eye color for four hair colors in female students. The data is from the HairEyeColor data set. This type of plot is called a grouped bar plot. How does the base R graphics package deal with that? You begin by isolating the female data in the HairEyeColor data set, which lives in the datasets package:.
To begin producing the image above, you have to specify the colors in the bars and in the legend:. Now you turn once again to the barplot function. Interestingly, if you use females as the first argument for barplotR draws a plot with Eye Color on the x-axis rather than Hair Color.
To reverse that, you use t to interchange transposein other words the rows and columns:. Try it without this argument and watch what happens. The first argument puts the legend at the top of the plot, and the second argument provides the names. The third argument specifies the size of the characters in the legend —.
In addition, he has written numerous articles and created online coursework for Lynda. Grouping the Bars on a Bar Plot with R.

It is possible to toggle single traces by clicking on them in the legend. If traces are grouped using legendgroup like in the example above not the single traces but the whole group is toggled. It should be possible to disable the toggling of the whole group and instead toggle the single traces like in no-grouped legends. This would make it possible in the example above to only disable the "points" and only show the "avarage line" of this group.
Related : 65, Can I ask why are you using legend groups if you don't want group toggling? I suspect you like the legend group aesthetics, but I'd like to confirm.
Each sub-chart has its own legend-group. It is amazing, what is possible with plotly. This seems like a good idea for what I am doing too, but it is possible there is another way to approach my use case that I haven't seen.
So I am using subplots in order to have common x or y axis, what I would then like is for the legend to be aligned with the subplot rather than the whole group.
I can split the legend up by using legend groups, but it is tricky to perfectly align them I can get close with judicious use of tracegroupgapbutthen I run into the problems mojoaxel had. Maybe there is a way of having common axis between plots rather than subplots, or some other option I haven't noticed.
I have the same issue. To me, the group legend should honor the individual toggling or make it a configurable thing. I have the same issue too, as I suspect anyone serious about plotting data is having.
Need subplots to have common zooming, panning, etc Therefore need legendgroup to separate legends on subplots. Need individual toggling to identify "stuff". The current state of play does not permit all three. Probably easiest fix is to permit separate legends per subplot. All should fall into place from there.
Maybe the solution will come from first having separate legends per sublot, OlderSchool suggests. Skip to content. Dismiss Join GitHub today GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

We had discussions a long time ago about an idea I was calling "legends 2. For example, assuming the plot you've made above used one trace with variable color and symbol, its legend could be an annotation like syntax off the top of my head For the record, I don't know if other platforms implement a system like this but I'll note that this concept is inspired by a very similar system in Igor Pro.
Seconding this, it would be useful. On some data I'm currently working on, plotly used in R through the corresponding package outputs something like this:. It could be much simpler, plus it's not shown in the above picture but the factor levels are also concatenated between the two legend types being used, which is a bit ugly it adds " " and the spacing syntax is not correct. I third this! It could be nice to be able to have legends specific to a give subplot rather than having to list all items in one legend.
This would be great for when there are multiple y axesso that traces are more obviously linked to the relevant y axis. The grouping still doesn't work as a substitute, mostly because you cannot highlight individual traces, only legend groups. Is there any update on this? I would really like to know how to attach a legend on the right hand side of each subplot. I was excited to see that this issue had been raised two years ago, hoping that it would be solved. Has there been any progress? Going to add another bump to this.
I'm particularly interested in the interaction with ggplotly, since currently the lack of support for multiple legends changes the plot in unexpected ways. So it basically would look like the mockup above where the legend groups have text above them. Indeed, it would be great to have multiple legends available! It would also solve this issue with ggplotly Agree with russellromney Having a separate legend option for each subplot is a high priority issue!
