+# Data points
+
+Plotting the raw data points is probably the most bare bone way to visualize a dataset. the corresponding function in tidyplots is called `add_data_points()`.
+
+```{r}
+animals %>% 
+  tidyplot(x = weight, y = size) %>% 
+  add_data_points()
+```
+
+In the above example some data points appear to overlap other points. To account for this so called _overplotting_, you might want to add a thin white border around the points. This is achieved by setting the parameter `confetti = TRUE`.
+
+```{r}
+animals %>% 
+  tidyplot(x = weight, y = size) %>% 
+  add_data_points(confetti = TRUE)
+```
+
+Another way is to make the points transparent using the `alpha` parameter.
+
+```{r}
+animals %>% 
+  tidyplot(x = weight, y = size) %>% 
+  add_data_points(alpha = 0.3)
+```
+
+Or by changing the plotting symbol to an open `shape`.
+
+```{r}
+animals %>% 
+  tidyplot(x = weight, y = size) %>% 
+  add_data_points(shape = 1)
+```
+
+However, data points can also be used when plotting a _discrete variable_ like `treatment` against a _continuous variable_ like `score`.
+
+```{r}
+study %>% 
+  tidyplot(x = treatment, y = score) %>% 
+  add_data_points()
+```
+
+To avoid overplotting in this scenario, there are two additional options. You can add some random noise or _jitter_ to the y position.
+
+```{r}
+study %>% 
+  tidyplot(x = treatment, y = score) %>% 
+  add_data_points_jitter()
+```
+
+Alternatively, you can use an algorithm that keeps the points centered and just moves potentially overlapping points to the sides.
+
+```{r}
+study %>% 
+  tidyplot(x = treatment, y = score) %>% 
+  add_data_points_beeswarm()
+```
+
 # Amounts
 
-# Distributions
+For some datasets, it makes sense to `count` or `sum` up, data points in order to arrive to a conclusion. As one example, let's have a look at the `spendings` dataset.
+
+```{r results='markup'}
+spendings
+```
+
+As you can see, this dataset contains family spendings over a time period of 15 days in October. Here, it might be informative to see which spending categories are reoccurring and which are just one time spendings.
+
+```{r}
+spendings %>% 
+  tidyplot(x = category) %>% 
+  add_count_bar()
+```
+
+One thing to note here is that the x axis labels are overlapping and are thus unreadable. There are at least two possible solutions for this. One is to swap the x and y axis.
 
 ```{r}
+spendings %>% 
+  tidyplot(y = category) %>% 
+  add_count_bar()
+```
+
+The other one is to rotate the x axis labels.
+
+```{r}
+spendings %>% 
+  tidyplot(x = category) %>% 
+  add_count_bar() %>% 
+  adjust_x_axis(rotate_labels = TRUE)
+```
+
+Now we can appreciate that this family had reoccurring spendings for _Food_ but just one spending for _Housing_.
+
+Next, we ask the question how much was spend on each of the categories by plotting the `sum` amount.
+
+```{r}
+spendings %>% 
+  tidyplot(x = category, y = amount, color = category) %>% 
+  add_sum_bar() %>% 
+  adjust_x_axis(rotate_labels = TRUE)
+```
+
+Note that we had to introduce the parameter `y = amount` in the `tidyplot()` function to make it clear which variable should be summed up.
+
+I also added `color = category` in the `tidyplot()` function to have the variable `category` encoded by different colors.
+
+Since the data labels for the variable `category` are now duplicated in the plot, one could argue that it would be justified to remove the duplicated information on the x axis.
+
+```{r}
+spendings %>% 
+  tidyplot(x = category, y = amount, color = category) %>% 
+  add_sum_bar() %>% 
+  adjust_x_axis(rotate_labels = TRUE) %>% 
+  remove_x_axis_labels() %>% 
+  remove_x_axis_title() %>% 
+  remove_x_axis_ticks()
+```
 
+Note that besides the x axis labels, I also removed the x axis ticks and x axis title to achieve a clean look.
+
+Of course you are free to play around with different graphical representations of the sum values. Here is an example of a lollipop plot constructed from a thin `bar` and a `dot`.
+
+```{r}
+spendings %>% 
+  tidyplot(x = category, y = amount, color = category) %>% 
+  add_sum_bar(width = 0.03) %>% 
+  add_sum_dot() %>% 
+  add_sum_value(accuracy = 1) %>% 
+  adjust_x_axis(rotate_labels = TRUE) %>% 
+  remove_x_axis_labels() %>% 
+  remove_x_axis_title() %>% 
+  remove_x_axis_ticks()
+```
+
+I also added the sum value as text label using the `add_sum_value()` function. 
+
+# Heatmaps
+
+Heatmaps are a great way to plot a _continuous variable_ across to two _discrete variables_. To exemplify this, we will have a look at the `gene_expression` dataset.
+
+```{r results='markup'}
+gene_expression %>% 
+  dplyr::glimpse()
+```
+
+I used the `dplyr::glimpse()` function from the dplyr package get a nice overview of all variables including in the dataset. We will start by plotting the `expression` values of each `external_gene_name` across the `sample` variable.
+
+```{r}
+gene_expression %>% 
+  tidyplot(x = sample, y = external_gene_name, color = expression) %>% 
+  add_heatmap()
+```
+
+One thing to note here is that the y axis labeks are overlapping. So let's increase the height of the plot area from 50 to 80 mm.
+
+```{r fig.height=5}
+gene_expression %>% 
+  tidyplot(x = sample, y = external_gene_name, color = expression) %>% 
+  add_heatmap() %>%
+  adjust_plot_area_size(height = 80)
+```
+
+The next thing to note is that some of the rows like _Map1a_ and _Kif1a_ show very high expression while others show much lower values. Let's apply a classical technique to reserve the variations in the color for differences within each  row. This is done by calculating _row z scores_ for each row individually. Luckily, tidyplots does this for us when setting the parameter `scale = "row"` withing the `add_heatmap()` function call.
+
+```{r}
+gene_expression %>% 
+  tidyplot(x = sample, y = external_gene_name, color = expression) %>% 
+  add_heatmap(scale = "row") %>%
+  adjust_plot_area_size(height = 80)
+```
+
+Now it much easier to appreciate the dynamics of individual genes across the samples on the x axis.
+
+However, the rows appear to be mixed. Some having rather high expression in the "Eip" samples while others have high value in the "Hip" samples. Conveniently, in the dataset there is a variable called `direction`, which is either "up" or "down". Let's use this variable to sort our y axis.
+
+```{r}
+gene_expression %>% 
+  tidyplot(x = sample, y = external_gene_name, color = expression) %>% 
+  add_heatmap(scale = "row") %>%
+  adjust_plot_area_size(height = 80) %>% 
+  sort_y_axis_labels(direction)
+```
+
+This starts looking like a classical gene expression heatmap
