Diagonal Stripes and Bars

Diagonal stripes and bars

You could use a triangle on :after :pseudo-element for the first image and linear-gradient for the second image.

To get the cuts, the part of the linear-gradient have been set to transparent.

How do I create and distribute diagonal stripes on a rectangle?

Using a gradient fill to draw lines

On trashgod's tip I tried filling a shape with a gradient that had sharp edges to simulate line drawing. This would prevent a lot of calculations and could potentially be a lot simpler. It worked quite ok for thick lines, but not for thinner lines. Using the following code produces the fill in the first picture:

    rect.setSpace(spaceBetweenLines);
    Color bg = Color.YELLOW;
    Color fg = Color.BLUE;
    rect.setPaint(new LinearGradientPaint(
            (float) startX, (float) startY, (float) (startX + spaceBetweenLines), (float) (startY + spaceBetweenLines),
            new float[] {0,.1f,.1001f}, new Color[] {fg,fg,bg}, MultipleGradientPaint.CycleMethod.REPEAT)
    );

Drawing lines using graphic primitives

Although simpler it did not work in my case. The more elaborate, but to me, more natural way of doing it, is simply drawing lines on top of the shape (rectangle, cirle, ...). The following code was used in producing the second image. Observe the use of the clip(Shape s) to restrict the line drawing to the shape underneath. The reason for not simply drawing a rectangle and using clip() to limit the shape is that the clip() operation is not aliased, thus producing jaggies. Therefore I have to draw the shape first to get smooth edges, then set the clip to prevent overflow in the forthcoming line drawing, and finally draw the lines.

public void paint(Graphics g) {
    Graphics2D g2 = (Graphics2D) g;
    g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);

    g2.setPaint(getBackground());
    g2.fill(getShape());
    g2.setClip(getShape());

    // draw diagonal lines
    g2.setPaint(getLineColor());

    for (int x = (int) this.x, y = (int) (this.y); y - height < (this.y + height + getSpace()); ) {
        g2.drawLine(x, y ,  x + (int) width , y  - (int) width);

        y += getSpace();
    }

How can I add hatches, stripes or another pattern or texture to a barplot in ggplot?

One approach is to use the ggpattern package written by Mike FC (no affiliation):

library(ggplot2)
#remotes::install_github("coolbutuseless/ggpattern")
library(ggpattern)
ggplot(data = df, aes(x = Class, fill = StudyTime, pattern = Nerd)) +
  geom_bar_pattern(position = position_dodge(preserve = "single"),
                   color = "black", 
                   pattern_fill = "black",
                   pattern_angle = 45,
                   pattern_density = 0.1,
                   pattern_spacing = 0.025,
                   pattern_key_scale_factor = 0.6) + 
  scale_fill_manual(values = colorRampPalette(c("#0066CC","#FFFFFF","#FF8C00"))(4)) +
  scale_pattern_manual(values = c(Nerd = "stripe", NotNerd = "none")) +
  labs(x = "Class", y = "Number of Students", pattern = "Nerd?") + 
  guides(pattern = guide_legend(override.aes = list(fill = "white")),
         fill = guide_legend(override.aes = list(pattern = "none")))

The package appears to support a number of common geometries. Here is an example of using geom_tile to combine a continuous variable with a categorical variable:

set.seed(40)
df2 <- data.frame(Row = rep(1:9,times=9), Column = rep(1:9,each=9),
                   Evaporation = runif(81,50,100),
                   TreeCover = sample(c("Yes", "No"), 81, prob = c(0.3,0.7), replace = TRUE))

ggplot(data=df2, aes(x=as.factor(Row), y=as.factor(Column),
                     pattern = TreeCover, fill= Evaporation)) +
  geom_tile_pattern(pattern_color = NA,
                    pattern_fill = "black",
                    pattern_angle = 45,
                    pattern_density = 0.5,
                    pattern_spacing = 0.025,
                    pattern_key_scale_factor = 1) +
  scale_pattern_manual(values = c(Yes = "circle", No = "none")) +
  scale_fill_gradient(low="#0066CC", high="#FF8C00") +
  coord_equal() + 
  labs(x = "Row",y = "Column") + 
  guides(pattern = guide_legend(override.aes = list(fill = "white")))
