mydata = {{44970, 2357.7}, {54324, 1859.34}, {49500, 1797.44}, {54161,
1432.26}, {49505, 1421.2}, {49605, 1292}, {54640, 1260}, {39503,

BarChart[#[[2]] & /@ mydata, ChartLabels -> (#[[1]] & /@ mydata)]
BarChart[Last /@ mydata, ChartLabels -> First /@ mydata]
BarChart[Last /@ #, ChartLabels -> First /@ #] &[mydata]
BarChart[mydata[[All, 2]], ChartLabels -> mydata[[All, 1]]]
BarChart[#[[All, 2]], ChartLabels -> #[[All, 1]]] &[mydata]
% === %% === %%% === %%%% === %%%%%
True
However, to find anything on this chart by label (particularly if "actual data is much larger"), then sorting might be useful.
sortedData = Sort[mydata];
BarChart[Last /@ #, ChartLabels -> First /@ #] &[sortedData]

Given
mydata={{44970, 2357.7}, {54324, 1859.34}, {49500, 1797.44}, {54161,
1432.26}, {49505, 1421.2}, {49605, 1292}, {54640, 1260}, {39503,
760}, {49525, 711.31}, {43324, 617.1}}
This should be simple, but I can't seem to find the answer. I want a
BarChart of the second values {2357.7, 1859.34,....}, labeled with the
corresponding first value. This comes close, but all "bars' are
labeled with 44970, not sequentially.
;
BarChart[{#[[2]]} & /@ mydata, ChartLabels -> {#1} & /@ mydata]
The actual data is much larger, precluding simply entering the ten
values given above. Can someone point me in the right direction?
Thanks in advance
