Tikz legend position

The goal of this R tutorial is to describe how to change the legend of a graph generated using ggplot2 package. Make sure that the variable dose is converted as a factor variable using the above R script. The allowed values for the arguments legend. Note that, the argument legend. In this case it is possible to position the legend inside the plotting area.

Their values should be between 0 and 1. The R code below creates a scatter plot. The color and the shape of the points are determined by the factor variables cyl and gear, respectively. The size of the points are controlled by the variable qsec. In this case the argument guide is used as follow :.

This analysis has been performed using R software ver. Data Example of plot Change the legend position Change the legend title and text font styles Change the background color of the legend box Change the order of legend items Remove the plot legend Remove slashes in the legend of a bar plot guides : set or remove the legend for a specific aesthetic Default plot without guide specification Change the legend position for multiple guides Change the order for multiple guides Remove a legend for a particular aesthetic Infos.

Pgfplots package

Montrez-moi un peu d'amour avec les like ci-dessous Recommended for You! Practical Guide to Cluster Analysis in R. Network Analysis and Visualization in R. More books on R and data science.The pgfplots package is a powerful tool, based on tikzdedicated to create scientific graphs. Pgfplots is a visualization tool to make simpler the inclusion of plots in your documents. Since pgfplot is based on tikz the plot must be inside a tikzpicture environment.

Inside the squared brackets some options can be passed, in this case we set the colour of the plot to red ; the squared brackets are mandatory, if no options are passed leave a blank space between them.

Inside the curly brackets you put the function to plot. Is important to remember that this command must end with a semicolon. To put a second plot next to the first one declare a new tikzpicture environment. Do not insert a new line, but a small blank gap, in this case hskip 10pt will insert a 10pt-wide blank space. This will add a 3dplot, and the option surf inside squared brackets declares that it's a surface plot.

The function to plot must be placed inside curly brackets. Again, don't forget to put a semicolon ; at the end of the command. This way the code is more readable and is easier to add further options if needed.

Open an example of the pgfplots package in Overleaf. To include pgfplots in your document is very easy, add the next line to your preamble and that's it:.

Some additional tweaking for this package can be made in the preamble. To change the size of each plot and also guarantee backwards compatibility recommended add the next line:. This changes the size of each pgfplot figure to 10 centimeters, which is huge; you may use different units pt, mm, in.

The compat parameter is for the code to work on the package version 1. Since L a T e X was not initially conceived with plotting capabilities in mind, when there are several pgfplot figures in your document or they are very complex, it takes a considerable amount of time to render them. To improve the compiling time you can configure the package to export the figures to separate PDF files and then import them into the document, add the code shown below to the preamble:.

See this help article for further details on how to set up tikz-externalization in your Overleaf project. Pgfplots 2D plotting functionalities are vast, you can personalize your plots to look exactly what you want.

Nevertheless, the default options usually give very good result, so all you have to do is feed the data and L a T e X will do the rest:. Scientific research often yields data that has to be analysed.

The next example shows how to plot data with pgfplots :. Scatter plots are used to represent information by using some kind of marks, these are common, for example, when computing statistical regression. Lets start with some data, the sample below is to show the structure of the data file we are going to plot see the end of this section for a link to the L a T e X source and the data file :.Operators and Keywords. Legend entries may be specified as individual character string arguments, a character array, or a cell array of character strings.

If the first argument hax is an axes handle, then plot into this axis, rather than the current axes returned by gca. A plot must exist before legend is called. The optional parameter orient determines if the key elements are placed vertically or horizontally.

The allowed values are "vertical" default or "horizontal". The legend label text is either provided in the call to legend or is taken from the DisplayName property of graphics objects. If no labels or DisplayNames are available, then the label text is simply "data1""data2"…, "dataN". Implementation Note: A legend is implemented as an additional axes object of the current figure with the "tag" set to "legend".

Properties of the legend object may be manipulated directly by using set. Figure 1. The optional parameter pos specifies the location of the legend as follows: pos location of the legend north center top south center bottom east right center west left center northeast right top default northwest left top southeast right bottom southwest left bottom outside can be appended to any location string The optional parameter orient determines if the key elements are placed vertically or horizontally.

The following customizations are available using option : "show" Show legend on the plot "hide" Hide legend on the plot "toggle" Toggles between "hide" and "show" "boxon" Show a box around legend default "boxoff" Hide the box around legend "right" Place label text to the right of the keys default "left" Place label text to the left of the keys "off" Delete the legend object The optional output values are hleg The graphics handle of the legend object.

The following code clf; colormap cool 64 ; surf peaks ; legend "peaks " ; title "legend works for surface objects too" ; Produces the following figure Figure 1.

The following code clf; plot rand 2 ; title "legend will warn if extra labels are specified" ; legend "Hello", "World", "interpreter", "foobar" ; Produces the following output warning: legend: ignoring extra labels and the following figure Figure 1. The following code clf; plot; title "a very long label can sometimes cause problems" ; legend "hello very big world", "location", "northeastoutside" ; Produces the following figure warning: legend: ignoring extra labels and the following figure Figure 1.Sign in to comment.

Aleksander Marek on 26 Sep Vote 1. Commented: dpb on 27 Sep I have an output function which I use with fmincon to plot some of variables during optimization process.

I use. However, as the optimization goes, I update my graph with:. And sometimes the legend overlaps with the new plot it doesn't reposition to adjust for new data. Is there any way I could reposition automatically my legend I guess apart from deleting it and constructing again every iteration?

I've created a block diagram and want to add a legend to it which should be positioned in the very top left corner.

I've setup a custom environment for the legend according to the answer to this question. Without the legend, this is my result:. However, when adding the legend at current bounding box. Why is adding the custom legend changing the bounding box and how can I position the legend at the top left corner of the first image?

The problem seems to be that you're setting the anchor of the legend outside the legend stylemeaning that it doesn't actually apply to the legend. Move it inside the legend styleand it works as expected. Unrelated: you can avoid some code repetition for example by the use of a scope environment as demonstrated below. Off-topic: With using TikZ library quotesdefining nodes, edge and edge quotes styles your MWE code become quite shorter:.

Dominic Dominic 2 2 bronze badges. Active Oldest Votes.Documentation Help Center. Legend properties control the appearance and behavior of a Legend object. By changing property values, you can modify certain aspects of the legend. Use dot notation to refer to a particular object and property:. Example: legend 'Location','northeastoutside'. If the legend has multiple columns, layout the items from top to bottom along each column.

If the legend has multiple columns, layout the items from left to right along each row. Example: legend 'Orientation','horizontal'. Number of columns, specified as a positive integer.

If there are not enough legend items to fill the specified number of columns, then the number of columns that appear might be fewer. Use the Orientation property to control whether the legend items appear in order along each column or along each row. Example: lgd. Selection mode for the NumColumns value, specified as one of these values:.

How to update the position of legend with 'Best' Location?

To specify the value, set the NumColumns property. Custom location and size, specified as a four-element vector of the form [left bottom width height]. The first two values, left and bottomspecify the distance from the lower left corner of the figure to the lower left corner of the legend.

The last two values, width and heightspecify the legend dimensions. The Units property determines the position units. Setting this property has no effect when the parent container is a TiledChartLayout.

This property affects the Position property. If you change the units, then it is good practice to return it to its default value after completing your computation to prevent affecting other functions that assume Units is the default value.

If you specify the Position and Units properties as Name,Value pairs when creating the object, then the order of specification matters. If you want to define the position with particular units, then you must set the Units property before the Position property.Pgfplots provides a friendly and well documented interface for creating plots with normal or logarithmic scaling. Axes, legends and labels are added easily.

Download pgfplots from CTAN. Just ask in the LaTeX Forum. Oder frag auf Deutsch auf TeXwelt. Take a look at the change log. There are several entries there related to 3D plotting. Is is also possible to draw the legend outside of the diagram? For exemple above in the center, below the title? I have a question regarding logarithmic plots. I'm trying to export a 3D plot from matlab into tex through the use of pgfplots and the function "matlab2tikz".

In this 3D plot, all the axis are logarithmic axis but I cannot manage to import it properly into pgfplots. I know, that I could make a 2D plot with both axis being logarithmic axes by using the "loglogaxis" option. Is there any possibility of making a 3D plot with three logarithmic axis? Anas plotting big data by means of pgfplots typically requires a lots of time to wait while the TeX interpreter ponders on your.

Concerning bthe best choice might be to call "lualatex " which appears to have dynamic memory limits. If you have any other executable, you may want to enlarge the limits see the pgfplots manual for a brief howto. However, there is some complexity perhaps around x points?
