Hello all,
I'm hoping to construct a workflow which produces a simple tally table (using the "Count1" tool, "Count occurrences of each record", which is still shipped with the Galaxy core) and then draws this as a Pie Chart.
1. Using "Count1", generate tally table (a simple two column tabular file, counts and labels as c1 and c2) in the history.
2. Click on the tally table in the history to expand the green box
3. Click on the "Visualize" icon, pick "Charts", click on "Pie Chart"
4. Click "Draw" or the "Configuration" tab.
5. Change donut ratio to zero, show legend to true, and show labels output to true.
6. Click "Draw" or the "Add Data" tab.
7. Under "Select Columns", "Labels", pick c2
8. Under "Select Columns", "Values", keep default c1
9. Click "Draw"
10. Admire interactive Pie Chart
11. Click "Screenshot", offered PNG / SVG / PDF but these are only direct downloads (well, PDF is more complicated).
Question: How can I "save" a static snapshot of the Pie Chart as a new history item (other than downloading it locally and then uploading it)?
Question: If so, can I then turn this history into a workflow which would recreate the pie chart?
As a work around I could write a traditional Galaxy tool which takes as input data files(s) and pre-sets the columns and visualisation settings, and produces static image(s) as output (e.g. PDF and PNG).

I should add that I've tried this on both the latest Galaxy from GitHub running locally as my development server, and with the current stable release at http://usegalaxy.org Also the "Screenshot" button has a camera icon (makes sense). I'd like a "Save" button (using the disk icon) as well or instead. Meanwhile the "Draw" button (used in steps 4, 6, 9) has a disk icon which seems somewhat confusing to me (it doesn't save - it takes you to another interactive page within Galaxy). Peter
