Create a dual bar chart comparing the calories and macronutrients in a list of foods

Contributed by: Gay Wilson

ResourceFunction["NutrientComparisonBarChart"][foods]

returns calories and macronutrient information in BarChart form for a list of foods.

ResourceFunction["NutrientComparisonBarChart"][foods,format]

returns calories and macronutrient information in the specified format.

Details and Options

NutrientComparisonBarChart returns a pair of bar charts. The first shows calories, and the second shows macronutrient content (protein, carbohydrates, fat, fiber).

Each bar represents the amount of the corresponding nutrient relative to 1 gram of that food (Cal/g and g/g). Hover over a bar to view the numeric value.

The following options are supported:

ChartLabels

Before

placement of food names

ChartStyle

Automatic

graphics style for charts

ChartLegends

Below

placement of nutrient properties

BarOrigin

Left

origin placement for bars

BarSpacing

Automatic

spacing between bars and bar groups

FontSize

font size of chart labels and legends

PlotLabel

optional overall label for both charts

ImageSize

600

overall image size expressed in points

ImageMargins

Automatic

absolute margins around image

Background

Automatic

background color for the charts

NutrientComparisonBarChart supports the following format values:

"Dataset"

returns a Dataset of the calories and macronutrient content in the foods

"Data"

returns associations of the foods and their calories and macronutrient content

Examples

Basic Examples (2)

Compare the relative calories and macronutrients of raw fruits:

In[1]:=

Out[1]=

Visualize the nutrients in high-protein foods with a customized chart design:

In[2]:=

ResourceFunction[
"NutrientComparisonBarChart"][{"braised beef", "cooked lentils", "boiled eggs", "peanut butter", "fried tofu", "grilled chicken"}, ChartStyle -> "Pastel", BarSpacing -> "None", PlotLabel -> "High-Protein Foods", FontSize -> 12]

Out[2]=

Scope (2)

Display the nutrients data as a Dataset:

In[3]:=

ResourceFunction[
"NutrientComparisonBarChart"][{"braised beef", "cooked lentils", "boiled eggs", "peanut butter", "fried tofu", "grilled chicken"}, "Dataset"]

Out[3]=

Display the data as associations:

In[4]:=

ResourceFunction[
"NutrientComparisonBarChart"][{"braised beef", "cooked lentils", "boiled eggs", "peanut butter", "fried tofu", "grilled chicken"}, "Data"]

Out[4]=

Use Wolfram Language food entities instead of text strings:

In[5]:=

foodEntities = {Entity[
"Food", {EntityProperty["Food", "FoodType"] -> ContainsExactly[{
Entity["FoodType", "Spinach"]}], EntityProperty["Food", "AddedFoodTypes"] -> ContainsExactly[{}], EntityProperty["Food", "Preparation"] -> Entity[
"FoodPreparation", "Raw"]}], Entity[
"Food", {EntityProperty["Food", "FoodType"] -> ContainsExactly[{
Entity["FoodType", "Quinoa"]}], EntityProperty["Food", "AddedFoodTypes"] -> ContainsExactly[{}], EntityProperty["Food", "Preparation"] -> Entity[
"FoodPreparation", "Cooked"]}], Entity[
"Food", {EntityProperty["Food", "FoodType"] -> ContainsExactly[{
Entity["FoodType", "Salmon"]}], EntityProperty["Food", "AddedFoodTypes"] -> ContainsExactly[{}], EntityProperty["Food", "Preparation"] -> Entity[
"FoodPreparation", "Grilled"]}], Entity[
"Food", {EntityProperty["Food", "FoodType"] -> ContainsExactly[{
Entity["FoodType", "Carrot"]}], EntityProperty["Food", "AddedFoodTypes"] -> ContainsExactly[{}], EntityProperty["Food", "Preparation"] -> Entity[
"FoodPreparation", "Boiled"]}]};
