How to Rotate the X-Axis Labels 90 Degrees in Levelplot

How to rotate the x-axis labels 90 degrees in levelplot

As far as the rotation of the x-axis labels go, you have to use parameter scales (see ?xyplot for more information on lattice parameters). You want to modify only its x component: scales=list(x=list(rot=90)). In context:

levelplot(cor2,
          aspect="iso", scales=list(x=list(rot=90)),
          main="Correlation Matrix", col.regions=rgb.palette(120),
          cuts=100, at=seq(0,1,0.01))

Rotating axis labels in lattice() package - R

you can try this using rot instead of las

levelplot(matrix(runif(100),10,10), scales=list(y=list(rot=45), x=list(rot=45)))

Rotate label text in seaborn factorplot

You can rotate tick labels with the tick_params method on matplotlib Axes objects. To provide a specific example:

ax.tick_params(axis='x', rotation=90)

How to change the breaks in date axis + rotate them 90 degrees

Use axis.timeDate with las=2 like this:

library(timeSeries)

tt <- timeSeries(seq(10,70,10), as.Date("2000-01-10") + 0:6)

plot(tt, axes = FALSE)
box()
ok <- as.numeric(format(time(tt), "%w")) %in% 0:2
axis.timeDate(1, at = time(tt)[ok], format = "%a", las = 2)

Rotate Y-axis categorical label in Seaborn plot?

Most stackoverflow answers would recommend using ax.set_yticklabels(rotation = 90), while this does work, it also requires you to provide the positional parameter labels (failing to provide this will give you a TypeError). I'd recommend using plt.yticks(rotation = 90). This is how it'd look:

import seaborn as sns
import matplotlib.pyplot as plt

sns.set(style="whitegrid")
tips = sns.load_dataset("tips")
ax = sns.violinplot(y="day", x="total_bill", data=tips)
plt.yticks(rotation = 90)
plt.show(ax)

Adjusting font size of axis labels in levelplot function in R

And THE WINNER IS:

pdf('corr.pdf')
data <- read.table("test", header=T)
z <- cor(data)
heatmap.2(z, Rowv=FALSE, Colv=FALSE, dendrogram="none", 
          key=TRUE, density.info="none", trace="none", 
          col=colorpanel(100, lowColor, highColor), scale="none",cexRow=0.3, cexCol=0.3 )
dev.off()

Diagonal labels orientation on x-axis in heatmap(s)

To fix pheatmap, all you really want to do is to go into pheatmap:::draw_colnames and tweak a couple of settings in its call to grid.text(). Here's one way to do that, using assignInNamespace(). (It may need additional adjustments, but you get the picture ;):

library(grid)     ## Need to attach (and not just load) grid package
library(pheatmap)

## Your data
d <- matrix(rnorm(25), 5, 5)
colnames(d) = paste("bip", 1:5, sep = "")
rownames(d) = paste("blob", 1:5, sep = "")

## Edit body of pheatmap:::draw_colnames, customizing it to your liking
draw_colnames_45 <- function (coln, ...) {
    m = length(coln)
    x = (1:m)/m - 1/2/m
    grid.text(coln, x = x, y = unit(0.96, "npc"), vjust = .5, 
        hjust = 1, rot = 45, gp = gpar(...)) ## Was 'hjust=0' and 'rot=270'
}

## For pheatmap_1.0.8 and later:
draw_colnames_45 <- function (coln, gaps, ...) {
    coord = pheatmap:::find_coordinates(length(coln), gaps)
    x = coord$coord - 0.5 * coord$size
    res = textGrob(coln, x = x, y = unit(1, "npc") - unit(3,"bigpts"), vjust = 0.5, hjust = 1, rot = 45, gp = gpar(...))
    return(res)}

## 'Overwrite' default draw_colnames with your own version 
assignInNamespace(x="draw_colnames", value="draw_colnames_45",
ns=asNamespace("pheatmap"))

## Try it out
pheatmap(d)
