Vega-Lite layered chart: how to get tick marks and tick labels to span the entire axis?

like below fixes the issue When you use a bin transform within an encoding, Vega-Lite adjusts the default axis properties to match the binning. You can re-adjust these manually via the encoding's scale and axis properties, but I think a simpler way is to move the bin transform to the chart's transform specification. Here is an example (Vega Editor):
code :
  "$schema": "https://vega.github.io/schema/vega-lite/v4.json",
  "data": {"url": "data/movies.json"},
  "transform": [
    {"calculate": "2*datum.IMDB_Rating", "as": "UpperLimit"},
      "bin": true,
      "field": "IMDB_Rating",
      "as": ["IMDB_Rating_0", "IMDB_Rating_1"]
  "layer": [
      "mark": "bar",
      "encoding": {
        "x": {
          "field": "IMDB_Rating_0",
          "type": "quantitative",
          "bin": "binned"
        "x2": {"field": "IMDB_Rating_1"},
        "y": {"aggregate": "count", "type": "quantitative"}
      "mark": "rule",
      "encoding": {
        "x": {
          "aggregate": "max",
          "field": "UpperLimit",
          "type": "quantitative"
        "color": {"value": "red"},
        "size": {"value": 5}

Matplotlib so log axis only has minor tick mark labels at specified points. Also change size of tick labels in colorbar

I hope this helps you . 1) Use FixedLocator to statically define explicit tick locations.
2) Colorbar cbar will have an ax attribute that will provide access to the usual axis methods including tick formatting.
code :
import numpy as np
import matplotlib.pyplot as plt

fig = plt.figure()
ax = fig.add_subplot(111)
x = np.arange(10,3000,100)
y = np.arange(10,3000,100)
X,Y = np.meshgrid(x,y)
Z = np.random.random(X.shape)*8000000
surf = ax.contourf(X,Y,Z, 8, cmap=plt.cm.jet)
ax.set_ylabel('Log Frequency (Hz)')
ax.set_xlabel('Log Frequency (Hz)')
# defining custom minor tick locations:
cbar = fig.colorbar(surf, shrink=0.5, aspect=20, fraction=.12,pad=.02)
# access to cbar tick labels:
def show_only_some(x, pos):
    s = str(int(x))
    if s[0] in ('2','5'):
        return s
    return ''


R, Change distance between axis tick marks and tick mark labels

this will help Quick solution is to put las=2 in both your barplot() and axis() calls to make labels horizontal and they'll be clearer.
EDIT: Use mtext instead of axis:

Alternating length of axis tick marks in ggplot edit: major and minor tick marks

By : hasham.98

this will help Ok, got this figured out with help from jhoward above and this question.
The trick is to plot the minor tick marks in the original plot, then add the major tick marks using annotation_custom.
code :
# base plot
base <- ggplot(plots, aes(age,installation)) +
  geom_point() +
  scale_y_discrete(breaks=levels(plots$installation)[c(2,4,6,8,10)]) +
  scale_x_continuous(expand=c(0,1)) +

# add the tick marks at every other facet level
for (i in 1:length(plots$installation)) {
  if(as.numeric(plots$installation[i]) %% 2 != 0) {
    base = base + annotation_custom(grob = linesGrob(gp=gpar(col= "dark grey")),  
                              ymin = as.numeric(plots$installation[i]), 
                              ymax = as.numeric(plots$installation[i]), 
                              xmin = -1.5, 
                              xmax = 0)

# add the labels at every other facet level
for (i in 1:length(plots$installation)) {
  if(as.numeric(plots$installation[i]) %% 2 != 0) {
    base = base + annotation_custom(grob = textGrob(label = plots$installation[i], 
                                                    gp=gpar(col= "dark grey", fontsize=10)),  
                                    ymin = as.numeric(plots$installation[i]), 
                                    ymax = as.numeric(plots$installation[i]), 
                                    xmin = -2.5, 
                                    xmax = -2.5)

# create the plot
gt <- ggplot_gtable(ggplot_build(base))
gt$layout$clip[gt$layout$name=="panel"] <- "off"

ggplot2: shorter tick marks for tick marks without labels (for y axis)

By : Schneider
Date : March 29 2020, 07:55 AM
I hope this helps you . The main issue is that you should be using marks = ticks$grobs[[2]]. There were some other issues with your code (which give's a warning 'data length is not a multiple of split variable') so here is a working minimal example:
code :
labs = seq(0,100,10)
labs[!!((seq_along(labs)-1)%%5)] = ''
g = ggplot(data.frame(x = 1:10, y = (1:10)^2), aes(x,y)) +
  geom_point() +
  scale_y_continuous(breaks = seq(0,100,10), labels = labs) +
  theme(axis.ticks.length=unit(10, "pt"))

gg = ggplotGrob(g)
yaxis <- gg$grobs[[which(gg$layout$name == "axis-l")]]  
ticks <- yaxis$children[[2]]
marks = ticks$grobs[[2]]
marks$x[c(2:5,7:10)*2-1] = unit(1, "npc") - unit(3, "pt")

# Put the tick marks back into the plot
ticks$grobs[[2]] = marks
yaxis$children[[2]] = ticks
gg$grobs[[which(gg$layout$name == "axis-l")]]  = yaxis

Altair/Vega-Lite tick chart: filter top K strips from aggregated field

By : user1296728
Date : March 29 2020, 07:55 AM
help you fix your problem Reading (and understanding) the documentation more in depth, I think I can state that what I asked is currently (June 2018) unfeasible with altair/Vega-Lite. Here it is my explanation...
Performing an aggregate transform on the data, is equivalent of adding a GROUP BY clause on a SQL query so we are no more able to associate to an encoded channel any “original” data field in its “unaggregated” form: when I try to refer to competition in the x channel this is therefore undefined.
code :
    x=alt.X(field='competition',type='temporal', timeUnit='yearmonthdate'),
        sort=alt.SortField(field='count', order='ascending', op='sum')
    window=[{'op': 'rank', 'as': 'rank'}],
    sort=[{'field': 'countX', 'order': 'descending'}]
).transform_filter('datum.rank <= 3').transform_lookup(
    from_=alt.LookupData(data=df, key='Sport',
  {"foo": 1, "bar": 1},
  {"foo": 1, "bar": 2},
  {"foo": null, "bar": 3}
  "type": "joinaggregate",
  "fields": ["foo", "bar", "bar"],
  "ops": ["valid", "sum", "median"],
  "as": ["v", "s", "m"]
  {"foo": 1, "bar": 1, "v": 2, "s": 6, "m": 2},
  {"foo": 1, "bar": 2, "v": 2, "s": 6, "m": 2},
  {"foo": null, "bar": 3, "v": 2, "s": 6, "m": 2}
