A Gantt diagram in Excel represents projects or tasks in the form of cascading horizontal bar charts. The Gantt chart bears a name of Henry Gantt, American mechanical engineer and management consultant who invented this chart as early as in 1910s. This short tutorial will explain the key features of the Gantt diagram, show how to make a simple Gantt chart in Excel, where to download advanced Gantt chart templates and how to use the online Project Management Gantt Chart creator.
However, one graph type remains opaque to many - the Gantt chart. I believe, every Excel user knows what a chart is and how to create it. So the question is how can I display the x-axis units generated by scale_x_date in quarters instead of dates? For example, instead of 21 Jan, I'd prefer Q1 21.If you were asked to name three key components of Microsoft Excel, what would they be? Most likely, spreadsheets to input data, formulas to perform calculations and charts to create graphical representations of various data types. , space = "free_y", scales = "free_y", switch = "both") Geom_line(size = 14, show.legend = FALSE) +ĭate_breaks = '3 months', date_minor_breaks = "1 month",įacet_grid(Category ~.
Then this code creates the Gantt chart (simplified for sharing): ggplot(df, aes(value, task, color = Category)) + Pivot_longer(3:4, names_to = "variable", values_to = "value") Task = fct_rev(factor(task, levels = (task))), Mutate(Category = (factor(Category, levels = (unique(Category)))),
The following sample code creates a dataframe (set up like this because it's relatively easy to edit on the fly): df % I've found a mostly serviceable approach, but I'd like to further improve my output. I'm preparing Gantt charts using ggplot2.
