Is it possible to create multiple legend in Matplotlib?

Multiple Legends¶ Sometimes when designing a plot you’d like to add multiple legends to the same axes. Unfortunately, Matplotlib does not make this easy: via the standard legend interface, it is only possible to create a single legend for the entire plot. If you try to create a second legend using plt.legend() or ax.legend(), it

How to customize the legend of a plot in Python?

For more information on available legend options, see the plt.legend docstring. As we have already seen, the legend includes all labeled elements by default. If this is not what is desired, we can fine-tune which elements and labels appear in the legend by using the objects returned by plot commands.

Can a 2D surface plot a 3D surface?

Can you use restrict y to domain in pgfplots?

While this might not be that surprising, you will have to notice that you can’t use domain, as well. The domain setting will be assumed to be described by the lowest and the highest sample point defined in your samples at directive. Using restrict y to domain helps you avoiding the pole issue.

What makes a coon patch A Coons patch?

One key characteristic of the patch is that its geometric shape can be controlled or adjusted by not only altering the corner points, but also the tangent vectors and twister vectors. By imposing required properties on these vectors, we can designate a Coons patch to represent specific surfaces.

Is there a way to color the bars of a barchart based on the bar’s value. For example: I have found some basic examples of bar coloring but nothing which can cater for value ranges, such as the above examples. Thank you kikocorreoso for your suggestion.

How to adjust the height of a plot?

If you want the plots to adjust their height depending on the number of bars, you can define the length of a unit in the y direction, by setting y=0.5cm, for instance. If you then define the bar width to be 0.4cm, there will be no overlap between the bars.

Can you use QtiPlot to make a box plot?

QtiPlot is a free program that can take your spreadsheet data and create a box plot with a consistent look. You can change the title, x-axis, etc., and then export the image into a .tex file thereby generating all the code from \\begin {tikzpicture} to \\end {tikzpicture}. Copy that code into your LaTeX document.

I need to change the size of a PGFPlots tikzpicture in my LaTeX document. There are two different things, scaling the graphic to the full or half width for example and changing the aspect ratio of a graphic.

Can you add a legend to a plot in pgfplots?

The plot contains grid lines since we used the grid = major key. A legend can be provided for one or more \\addplot statements using the legend entries key. pgfplots accepts more than one \\addplot ; command, so we can just add our remaining data files.

How to communicate axis limits to pgfplots?

Everything which might affect the survey phase (computing axis limits, for example), needs to be communicated to pgfplots – that is, by means of a style with the /pgfplots/key prefix. Adding /pgfplots/spam/.style=…will solve the problem as good as \\pgfplotsset{spam/.style…}. – Christian FeuersängerNov 26 ’11 at 13:08

Older versions used xlabel absolute, i.e. an absolute distance between the axis and axis labels (now matter how large or small tick labels are). The initial setting keeps backwards compatibility. You are encouraged to use

How to create a boxplot with variable width in ggplot2?

Boxplots hide the category sample sizes. One way to tackle this issue is to build boxplot with width proportionnal to sample size. Here is how to do it with R and ggplot2.

How to set the width of the box in Matplotlib?

From the documentation there is a widths option: widths : array-like, default = 0.5 Either a scalar or a vector and sets the width of each box. The default is 0.5, or 0.15* (distance between extreme positions) if that is smaller.

How to calculate box plot limits in R?

The base R function to calculate the box plot limits is boxplot.stats. The help file for this function is very informative, but it’s often non-R users asking what exactly the plot means. Therefore, this post breaks down the calculations into (hopefully!) easy-to-follow chunks of code for you to make your own box plot legend if necessary.
