If you're new to working with data, or unsure about the best way to represent your data on a BBC story, here is a quick guide to best practice.
If you're familiar with producing data visualisations or working with graphs and charts, make sure you've been added to the IDT user list - to get on the list go to iSite and submit an access request.
Step By Step Guide
- Step 1: Log into iSite, and click on 'Create New->Datasets and Charts' (top-right):
- Step 2: Add a name for your chart/dataset:
- Step 3: Click ‘Launch' within the ‘Upload your data’ section:
- Step 4: Click 'Import Data' and choose a .csv file, or add the labels and data yourself. Save & Close when ready.
- Pie Chart Example: For pie charts, labels will be created from Column A:
- Line/bar Chart Example: For line and bar charts, labels will be created from Row 1. Column A will be your x-axis.
- Step 5: Click ‘Launch' within the ‘Build your chart’ section:
- Step 6: Customise your chart as needed, click refresh to review the animation.
- Step 7: When ready, click 'Save & Close' (top-right) to return to the iSite form.
- Step 8: Now, in iSite, click 'Save' and 'Preview' to view your chart in a responsive format. If you are happy, click 'Publish'.
- Step 9: Click ‘Launch' within the ‘Generate an image’ section.
- Step 10: Select the size of image that you wish to download (if you are creating an image for the app – leave as default and go to step 12):
- Step 11: Download your image:
Step 12: If you've finished editing the chart, copy the include path from iSite, and add it to your CPS story as an 'include'.
Note: If you use the News or Sport include, it will automatically be converted to an image on the mobile app to ensure it can be viewed.
Now, add an 'Include File' to your page in CPS:
Then paste the include path from iSite into the 'Web' field, and a name in 'Title':
- Step 13: Have a look at the chart on mobile as well as desktop, to make sure it looks OK.
Using data in a story
More and more data is available to journalists: Health data, schools data, spending data, sports data, data on pretty much anything. Often a simple graph is all you need in a story to really give the numbers some context. If a billion pounds was spent on a project this year, is that more or less than in previous years? What percentage is it of the department's total budget? How does that compare a similar in Denmark or France?
The IDT Charts tool allows journalists to enter or upload a simple dataset and generate line-graphs, bar-charts and pie-charts.
WARNING: IT IS EASY TO CREATE CONFUSING OR EVEN MISLEADING CHARTS. IF YOU'RE UNSURE ABOUT THE WAY YOU'RE USING DATA, CONSULT AN EDITOR OR SOMEONE IN THE VISUAL JOURNALISM TEAM.
Some example charts are shown below, with some information on their ideal usage.
Vertical Bar Charts
These are good for showing trends over time, and for grouping mulitple data sets:
Horizontal Bar Charts
Use these if you need many or long labels, or don't need to track data over time:
Use these for very large data sets, with many data points:
These help to visualise/compare proportions or percentages. Use fewer than 5 groups:
