Ggplot2 Theme with No Axes or Grid

ggplot2 theme with no axes or grid

Here is the way to plot only the panel region:

p <- ggplot() + geom_area (data=economics, aes(x = date, y = unemploy), linetype=0) +
  scale_x_date(expand = c(0,0)) + scale_y_continuous(expand = c(0,0)) +
  theme(line = element_blank(),
        text = element_blank(),
        title = element_blank())

gt <- ggplot_gtable(ggplot_build(p))
ge <- subset(gt$layout, name == "panel")

grid.draw(gt[ge$t:ge$b, ge$l:ge$r])

Ggplot2 change the position of y axis values after removing gridlines

Do you want something like that?

ggplot(tmp, aes(factor(X2 - 1), X1, fill = X3, label = round(X3, 2))) +
  geom_tile() +
  geom_text() +
  scale_fill_gradient(low = "springgreen", high = "darkgreen") +
  coord_fixed(.5) +
  theme(
    panel.grid.major.x = element_blank(),
    panel.grid.major.y = element_blank(),
    panel.grid.minor.x = element_blank(),
    panel.grid.minor.y = element_blank(),
    panel.background   = element_blank(),
    axis.title.x       = element_blank(),
    axis.title.y       = element_blank(),
    axis.ticks         = element_blank(),
    legend.position    = "none"
  )

The problem with y-lab spacing is due to the fact that your X2 var is continuous. So geom_tile() positions the center of your tiles at 1, 2, 3...23, with the width of a tile == 1. The left side of the first tile starts at 1 - .5 = 0.5, that is why there is an empty place between -.5 and .5 (no tiles with center at 0). Converting X2 into factor, will fix it without any additional readjustment.

You might want to fix margins of the plot, thought.

How do I remove legend/grid without using theme_void()?

EDIT: Updated as you have posted an image. You do not have a legend, so you do not need to remove it. You want to remove the axis lines, ticks, text, title and maybe(?) the panel grid lines:

pic <- ggplot(data = art_dat, mapping = aes(x = x, y = y, group = path_id,
                                                color = step_id)
              ) + 
  geom_path(
            size = .9,
            alpha = 1000, #transparency of the lines
            show.legend = FALSE
                        
            ) +
            coord_equal() + 
            theme_light() + 
            scale_color_scico(palette = "berlin") +
                theme(
        axis.line = element_blank(), 
        axis.text = element_blank(),
        axis.ticks = element_blank(),
        axis.title = element_blank(),
        panel.grid.major = element_blank(), # optional - remove gridlines
        panel.grid.minor = element_blank() # optional - remove gridlines
    )

How can I suppress the vertical gridlines in a ggplot2 plot?

Try using

scale_x_continuous(breaks = NULL)

This would remove all the vertical gridlines as well as x-axis tickmark labels.

scale y axis on a polar plot in ggplot

I think this is a bit of a bug, or at least a missing feature (equivalent behaviour in Cartesian co-ordinates could be prevented by setting hard limits via ylim in coord_cartesian, which is not available in coord_polar). There is no outer axis line in coord_polar, and a grid line seems to be used in its place, without respecting axis.line theme elements.

The only workaround I can find is somewhat "hacky", in that you can pass vectorized colours to the grid lines:

foo %>% 
  ggplot() +
  geom_point(aes(x = theta, y = r)) +
  coord_polar(clip = "off") +
  scale_y_continuous(limits = c(0, 90), expand = c(0, 0),  breaks = 90) +
  scale_x_continuous(limits = c(0, 360), expand = c(0, 0), 
                     breaks = c(0, 90, 180, 270)) +
  theme(panel.grid.minor   = element_blank(),
        panel.grid.major.y = element_line(colour = c("red", NA)))
