Combine Multiple Datasets Seamlessly


US Per Capita Gasoline Consumption Trends, Rebased to 100 in 2000
This particular analysis is notable for its seamless use of multiple data sources. This chart pulls data from two separate datasets and effortlessly combines them.

Tuhunga uses the consumption data from the USEnergy dataset, and the population data from the USLabor dataset, both of which are available to members at no charge.

Add Interactivity to Increase Richness


US Per Capita Gasoline Spending
Hover over individual points to see the dollar amounts shown interactively, thereby providing greater information content to the viewer.

This example expands upon the prior chart, and uses gasoline pricing data from the USCommerce dataset, also available at no charge.

These three datasets remain consistently linked together, thereby minimizing the potential for accidental error during analysis.

Build Histograms


Magnitude of Monthly Exchange Rate Changes Between US Dollar and Japanese Yen
This example uses the foreign exchange rates dataset that is available to all users.

The analysis computes the monthly change in the USD/JPY exchange rate, places the change into 1% wide buckets, and calculates the frequency of each bucket's occurence since 1980.

For those wishing to replicate this analysis, step-by-step instructions are detailed in Tutorial 3, Part I.
