Legends | Legends 4.20 gameserver prototype | Runtime Evironment library

I have a problem with drawing the legends in a ggplot. I have already searched the net for hours for a solution but have not found anything yet.

I am trying to create a ggplot with different line and polygon shapefiles. I draw the shapefiles with the function geom_sf(). The drawing is not a problem. My problem is related to the legend creation.

The goal is to create a plot that has a single legend and has all the different shapefile types including their colors and or fill astetic. That means, a line-shape should be represented in the legend as a simple line and a polygon-shape as a simple polygon. I have managed to do all that.

The main difficulty is that one of the polygonshape (for better readability) not only uses the "fill" argument as astetic but also the "color" argument.

If I create a plot where all polygonshapes always use the fill argument as astetic and all lineshapes always use the color argument as astetic everything works fine. But as soon as I include a polygonshape in the plot which uses both arguments at the same time, it destroys the whole legend structure. In this case, for example, the symbols for the line shapefiles suddenly have a frame and/or background although they should not have one.

Is it not possible to build something like this with ggplot or am I just being clumsy?

Summary:

Analogous to the minimal example created below, I would like to create a single legend in this plot where:

• A = a polygon symbol is without border (as it can be seen in the
  plot)
• B = a polygon symbol is with border (as seen in the plot) and
• C = a simple line without border or background (as it can be seen in the plot).

How do I get this to work?

I'm working with ggplot and treemapify to generate a treemap.

The problem is that some blocks are too small so i can't put text inside of them. I've been trying to use scale_fill_manual in order to generate some legends outside the graph by breaks argument but it comes with two problems. If I only specify the labels that I want, the other ones turn green and I can't change their fill collor. On the other hand, when I use all the labels it shows them all.

How can I choose which legends I want to show in the graph?

This is the code I'm currently working on:

I've built this new ggplot2 geom layer I'm calling geom_triangles (see https://github.com/ctesta01/ggtriangles/) that plots isosceles triangles given aesthetics including x, y, z where z is the height of the triangle and the base of the isosceles triangle has midpoint (x,y) on the graph.

What I want is for the geom_triangles() layer to automatically provide legend components for the height and width of the triangles, but I am not sure how to do that.

I understand based on this reference that I may need to adjust the draw_key argument in the ggproto StatTriangles object, but I'm not sure how I would do that and can't seem to find examples online of how to do it. I've been looking at the source code in ggplot2 for the draw_key functions, but I'm not sure how I would introduce multiple legend components (one for each of height and width) in a single draw_key argument in the StatTriangles ggproto.

This is a bit harder to explain than my last question because the problem is not exactly reproducible.

I am producing legends for a couple of maps and am drawing a box around both legends since one has only 1 item (a line feature) and the others are discrete fills (a polygon feature). Using geom_sf to plot both.

I end up with a weird artefact that looks like part of the lines are drawn twice with just a slightly shifted position.

I managed to produce a similar error with the iris dataset where legend.box.background is only partially drawn.

seaborn 0.11.0 and matplotlib 3.3.3

write the following code and you get the legend x as blue, y as orange. uncomment the last line before plt.show() now the legends are reversed even though I specified the hue_order in sns.kdeplot().

Consider the plot produced by the following reprex. Note that the ggplot has sensible legends, while in plotly, the legend is heavily duplicated, with one entry for each time the same category ("manufacturer") appears in each facet. How do I make the plotly legend better match that of the ggplot2 one?

As a follow up to this famous thread. I decided to ask a new question because this is more specifically for vertical legends, and the given answers still don't provide a fully satisfactory solution. For polygon key glyphs, there was a suggestion to increase the size of the margin between the actual polygon glyph and the key border, with a modification of the underlying draw_key function. However, this doesn't really work if I want to keep a border, e.g., in black.

And when using other geoms (e.g., geom_line), I don't even see how to increase the margin between glyph and border - on a brief glance at the draw_key function used in ggplot2:::GeomLine (it doesn't use an exported draw_key function), it is not clear to me where to modify this.

So, my question is if there is a way to change the actual space between the key glyphs that would allow to keep a border (e.g., color = "black"), and without increasing the glyph size.

I am using a dataset with the following columns: date, counts, country, engine, and type.

I have created a view with three charts using the repeat operator. The charts show dates on the X axis, counts on Y, and then the bars are split by either country, engine, or type.

I am happy with how things look but I would like to have three separate color legends, one for each domain (so a legend for countries, a legend for type, and a legend for engine). How do I do that?

Here is the link to the editor.

I have a point chart encoding color, size, and shape. By itself all three encodings are collapsed as a single legend. However layering a line chart that shares the same color results in the duplicated legend below. There is no difference when marking size and shape as independent but color as shared. When I disable the legend in the line chart's color encoding, the [top] color legend and all color information disappears. What can I do?
