I am new to using ggplot2 and am having some trouble with my graphs. I have a bar chart that looks like this:

I have a reproducible code that generates three independent datasets and a combined dataset mydata. The dataset3 have less values, especially missing some values for certain n categories.

My dataset has a model variable which contains 3 categories. The first two have full results while the last one miss some proportions of the data. When using ggplot, the last category is not shown on the legend but does show curves for occasions where the data are available. I want the legend to show all the categories and curves for all the categories. My code is as below,

I’m working on a new geom for ggplot2 that allows the user to alter the tint and shade of the colors by mapping it to an aesthetic. (If someone knows of a place this has already been implemented, please save me the headache!) I’ve got the basics of the geom figured out but I’m not sure that I’m applying the scales correctly because I’m having to rescale the data within draw_panel to use the colour groups instead of it happening automatically.

I want a simple line graph showing the total expenses for each department for each fiscal year.

I have a problem with customizing a linetype legend in ggplot. I use the following code to generate a plot having mapped the linetype aesthetics to the sample.

I’m trying to draw the three bar plots in one image.
For the example data, I have a question about setting the width of each plot.

This question already has answers here: How do I access the data frame that has been passed to ggplot()? (2 answers) Closed 2 days ago. I’m trying to access the data passed to a ggplot command in a scale_y_continuous ‘layer’ diamonds %>% filter(cut %in% c(“Very Good”), carat > 2.8) %>% ggplot(aes(x=table, y=price, fill=color)) + geom_bar(stat=”identity”, […]

I am trying to plot two lines with ggplot. The second line has a different scale and I would like to have a secondary axis for it, which is completely independent from the first.
