✍️Editing within an App
Our visualisations are always built through the Home or the Stories.
Whenever you create or edit one of these Layouts, you'll always have the same editing experience.
It's composed on 3 main parts:
Layout part
This is the main space in your edition. You can see the framework of your Layout, each element is composed of and configure them, in-situ like Narratives or that opens the configuration tab like for Charts.
For more information, dive in:
Configuration part
This is the left sidebar. It includes 2 tabs:
Datasets: In which you can select datasets that you will use for this layout.
Configuration: In which you can configure your charts, filters and KPI
Focus on Visualisations' configuration
Let's focus on the configuration of Charts, Tiles and HKPIs.
They are the heart of your data storytelling and are represented by:
Dimensions (observation axes of indicators): In Toucan, dimensions are often filled in "label", "x axis" but also "groups", "packs", etc...
Measures (numerical attributes): In Toucan, measures are often filled in "value", "y axis" but also "variation", "additional values", etc...
And, most of the time, you don't want to just describe your datasets (or then do a Tablechart) but you want to give a meaning to your data by aggregating or compute statistics over your data.
And that's what we introduce in our experience, the possibility to simply aggregate data when you configure your visualisation, in order to keep relatively high-level that can serves several questions, several stories.
Aggregations that you can apply to create a metric depends on the type of you data's column.
For integer and float
sum: returns the addition of the values in the column
average: returns the addition of the values in the column and divided by the number of rows
minimum: returns the smallest value in the column
maximum: returns the highest value in the column
first: returns the first value in the column (based on the order of rows)
last: returns the last value in the column (based on the order of rows)
count: returns the number of rows
count distinct: returns the number of times we have a unique value in a column
For the other types
count
count distinct
These measures are computed by aggregating the column chosen within the value field grouped by the column chosen within the label field
Info
If you're configuring other options that are considered as dimensions (groups, packs, etc...), those columns will be also used to aggregate your values.
Toolbar part
Finally, the toolbar will allow you to manage your edition. It's composed of, from left to right:
Clear changes: Resets your entire layout to last saved version. Useful when you perform changes on a Layout and don't want to save.
"Saved as draft": Layouts are saved at each changes, so even when you close your tab, you will retrieve all your work! On hover, you can see when was the last time we save your changes in the draft.
Finish Later: Allows you to leave edition without pushing your changes for other App Builders. When you'll be back on the edition of this Layout, your last changes will still be there.
Save changes: Saves you work and share this for all App Builders in the staging version.
Information
In order to share your app to all your end-users, you need to publish in production. More information here.
