Generate a publication-ready bar chart based on the input projection.

Bar plot operator

Description

The bar plot operator demonstrates how to generate a barplot image and markdown components based on the input projection.

Usage

Input projection	.
y-axis	numeric, values to be used in the y axis
x-axis (optional)	numeric / factor, values to be used in the x axis
row (optional)	factor, factor to be used to separate panels by rows
column (optional)	factor, factor to be used to separate panels by columns
colors	factor, values to be used to color the bars

Input parameters	.
input_var	parameter description

Output relations	.
Image	PNG of the plot in the computed tables.

Details

The computation is based on the ggplot2 R package.

barplot_example's Issues

Support for stacked bar charts

More customization options: text size and legend

I'd like to have a few more options added in order to customise the ggplot2 barplots, including:

• For each one of the following: title, subtitle, xlab anmd ylab to be able to control font size
• For the y- and x-axis tick labels to also be able to control font size
• The option to remove the legend
• The option to rename the legend title

Support for absence of color case

Error bar to the top only?

Is there any way to control the error bar, so that it only appears on top of the bars? Like in this figure:

And is this good practice or should be avoided as misleading?

Issue with barplot output

Check also this step: https://tercen.com/test-team/w/3d0482ed7ae6c2f2d24e5678cd5af239/ds/bbca4146-337c-468f-be93-280d29849c1f/crosstab

What I get in the computed barplot isn't what I expected, as not every group contain two measurements in the resulting barplot and the y axis range is much smaller than it should.

In this example I have only one measurement per color group within each x-axis tick.

Barplot improvements

• add themes
• add color scales. default, same as Tercen + option for a different one
• position_dodge to be customised
• error when jitter but no color
• error when "+" sign in row or column names (R formula conflict)
• customise nrow or ncol when single row / column

GitHub version problem on GUI

The barplot has a weird string instead of a version number.
It causes problem with the GUI if this operator is selected.

New feature: get the bar directly from the projection without computing aggregates per cell

At iTeos most use cases I had so far with the barplot operator is displaying the data as they are on the crosstab view without the need to compute any aggregates.

Itàd be gret if the barplot operatos had this feature too.
