Join two data sets by year in Tableau -


i have 2 datasets looks like:

# 2013_data.tsv year    state   age 2013    ca  22,5 2013    oh  19,3 2013    il  45,5 2013    tx  33  # 2012_data.tsv year    state   age 2012    ca  23 2012    oh  21,5 2012    ca  44,3 2012    tx  34,4

i want use year pager on tableau map.

how can join separate data sources?

you blend on year, if year different in each data source blend not match on , no results.

i guessing each data source (tsv file) has same format (same number of columns , column names). in case can extract each data source tableau desktop , add data each source master extract. (you appending data extracts):

enter image description here

and data in 1 extract:

enter image description here

from here simple combine years in 1 visualization.

also, since so, point out can programatically extract api (see https://www.tableau.com/learn/tutorials/on-demand/extract-api-introduction).

datatable - Matlab struct computations -

i download data yahoo! finance with: data = getyahoodailydata({'msft', 'axp'},'01/01/2000', '01/01/2015', 'dd/mm/yyyy'); and data stored 1x1 struct. want create tx2 matrix of daily adjusted closing prices msft , axp, column 7 in each table in struct. how can that? or better : there way make computations directly on information/prices in struct? you can access data in struct name. vecmsftadj = data.msft.adjclose; vecaxpadj = data.axp.adjclose; % if want n x 2 matrix madjclose = [vecmsftadj, vecaxpadj]; % personnaly prefer working table tadjclose = table; tadjclose.msftadj = vecmsftadj; tadjclose.axpadj = vecaxpadj;
