Getting started

This walk-through creates a composition from the Curve spread library template: two curves side by side, with the spread between them, tenor by tenor.

1. Open Composer​

Open Composer from the Extensions section of the menu. It opens on the Gallery (see The gallery). The Compositions tab lists the compositions in your organisation, with counts at the top: how many match the filters, how many are yours, how many came from a template, and how many templates there are.

2. Choose a template​

Open the Library tab. The templates are grouped by category (Curves, Power, Gas, Oil, Carbon, Timeseries and so on), with the featured ones first. Select Curve spread to see:

  • What it does
  • Its columns
  • The inputs it asks for

Select Preview to run it for today with its default inputs, then Use template.

3. Fill in the inputs​

The Use template dialog asks for:

FieldWhat to enter
NameA name for your composition, for example "Brent WTI"
Store inAn analytics area to keep it in, or A new analytics area (give it a name, such as "Oil Analytics"), or An existing master data record
The template's inputsFor Curve spread: the first curve, the second curve, and names for them. Start typing part of an id in a curve field to search.

Select Create composition. Composer saves the composition and opens it.

4. The workspace​

The composition opens in the workspace: a toolbar, the chart and the table.

Select a column heading in the table, or a series in the chart, to open that column in the side panel.

5. Add a column​

  1. Select Columns. The side panel slides out from the right, and the data moves left so you can still see it.
  2. Select Add expression column.
  3. Give it a Caption, such as "Spread %", and an Id, such as PCT.
  4. Type the Expression, for example SPREAD / B * 100. Suggestions appear as you type: the ids of the other columns, and the functions you can use.
  5. Under Display, choose how it is charted, for example a column on axis 2.

The panel shows Run to see your changes. Select Run, or close the panel, to see the new column.

6. Save it​

Select Save. The composition is saved where you chose in step 3, and appears in the Compositions tab.

tip

Composer keeps a record of the template a composition was created from, and the values it was given, under Properties.

The Gallery tab, the first tab in Composer, shows the compositions of one analytics area as cards. Each card shows the chart of the composition's latest build, with its indicators. A composition that has not been built yet shows a preview, calculated when you open the gallery.

  • Choose the analytics area to show.
  • Choose the Card width: 25%, 33%, 50% or 100% of the page. Each card also has its own width, so you can make one chart wide and keep the others small.
  • Drag a card by its grip, at the top left, to move it. Drop it on the left half of another card to put it before that card, or on the right half to put it after. Reset order puts the cards back in name order.
  • Select Refresh to show the latest builds.
  • Select a card to open the composition, on the ondate the card shows, as a chart, a table and chart, or a table, however it is set to show. Back returns to the gallery.

Composer remembers the area, the widths and the order of the cards for you, on any computer you sign in on.

Other ways to start​

New composition on the Compositions tab offers:

Describe it to Fusion AISay what you want in your own words, and Fusion finds the data and designs the columns. See Designing with Fusion AI.

Blank timeseries compositionAn empty timeseries worksheet
My template: ...One of your organisation's templates

On the Master Data screen, the Composer tab of a record does the same, and stores the composition on that record. When you use a template there, its curve and timeseries inputs are filled in with the record's own data, and the Columns panel offers the record's data items as columns in one click.
